Why Your Business Needs Chip and PIN in your EPoS System

Posted on

In the modern-day business landscape, efficiency and adaptability are paramount. One of the most effective ways to achieve this is through the integration of Chip and PIN technology into your Electronic Point of Sale (EPoS) system. This article delves into the intricate details of Chip and PIN technology, its benefits, and the transformation it brings to the retail and service industries.

Understanding Chip and PIN Technology

Introduced to the UK in the early 2000s, Chip and PIN technology revolutionised the way businesses handle transactions. This system allows customers to make payments using their debit or credit card by entering a unique four-digit Personal Identification Number (PIN) into a card reader. The machine then communicates with the card issuer, validating the transaction and transferring funds from the customer’s bank account to the business’s bank account.

The Chip and PIN technology alleviated the need for customers to sign receipts, reducing the risk of fraud and providing a more efficient, secure means of transaction. According to Statista, counterfeit losses on UK-issued cards fell from £110.6 million in 2003 to just £8.7 million in 2020, demonstrating the significant impact of Chip and PIN technology on reducing fraud.

What is EPoS?

Electronic Point of Sale (EPoS) is a computerised system used in retail stores, restaurants, and other businesses that need to track transactions, inventory, and customer information. EPoS systems offer a multitude of features, including sales tracking, inventory management, and customer relationship management. Integrating Chip and PIN technology into an EPoS system combines the efficiency of electronic transactions with the security and convenience of Chip and PIN payments.

The Symbiosis of Chip and PIN and EPoS Systems

The integration of Chip and PIN technology into an EPoS system offers numerous benefits for businesses. By combining these two technologies, businesses can streamline their operations, improve customer experience, and enhance their security measures. Let’s delve into the advantages of a Chip and PIN-integrated EPoS system.

What is a chip and pin?

“Chip and PIN” is a system for authenticating credit and debit card transactions, specifically designed to improve the security of electronic payments. Here’s how it works:

  1. Chip: Instead of relying solely on the magnetic stripe found on the back of traditional payment cards, the chip and PIN system uses an embedded microchip on the card. This chip is much more secure because it generates a unique transaction code for each purchase, making the card harder to clone or counterfeit.
  2. PIN: Instead of signing a paper receipt or just using the card without further authentication (as in many magnetic stripe systems), users are required to enter a Personal Identification Number (PIN) to validate their identity and approve the transaction. The PIN ensures that even if someone steals the card, they would need the associated PIN to use it.

Taken together, these measures significantly reduce the chances of fraud in card-present transactions. The system was first introduced in the UK in 2004 and has since been adopted in many countries around the world. 

Does the UK use chip and pin?

Yes, the UK was one of the pioneers in adopting the “chip and PIN” system. The UK introduced the system in 2004 as a means to combat increasing card fraud. Prior to the introduction of chip and PIN, cardholders in the UK typically validated card transactions with their signature.

Since the rollout of the system, the chip and PIN method has become the standard for card-present transactions in the UK. Cardholders are required to enter their PIN for most transactions when they use their credit or debit cards at terminals in shops, restaurants, and other point-of-sale locations.

The adoption of chip and PIN in the UK led to a significant reduction in card fraud resulting from lost, stolen, or counterfeit cards. Other countries observed the success of the system in the UK and have since adopted similar systems.

How do you chip and pin?

Using “chip and PIN” for a transaction is a straightforward process. Here’s a step-by-step guide on how to use it:

  1. Insert the Card: Insert your chip-equipped card into the card terminal (often called a Point of Sale or POS terminal). The chip should face up, and the end with the chip should go in first.
  2. Wait: The terminal will read the chip on your card. During this time, it’s essential to leave the card in the machine. The terminal will prompt you to proceed to the next step.
  3. Enter Your PIN: The terminal will ask you to input your Personal Identification Number (PIN). This is typically a 4-digit number (though it can be more in some cases) that you’ve either selected or been given by your bank. Use the keypad on the terminal to enter this number.
  4. Confirm: After entering your PIN, the terminal might ask you to press a button (like “OK” or “Enter”) to confirm the transaction.
  5. Wait for Authorisation: The terminal will then process the transaction. This involves communicating with the bank or card issuer to ensure the transaction can be approved. This usually takes a few seconds.
  6. Remove the Card: Once the transaction is authorised, the terminal will prompt you to remove your card.
  7. Receipt: Depending on the merchant or the settings you’ve established with your bank, you may be given a receipt or asked if you’d like a printed receipt or one sent to an email.
  8. Secure Your Card and Receipt: Once the transaction is complete, ensure you securely store your card and take your receipt (if you have one). It’s a good practice to regularly check your receipts against your bank or card statements to ensure there are no unauthorised transactions.


  • Never share your PIN with anyone.
  • If you forget your PIN or believe it’s been compromised, contact your bank or card provider to reset it.
  • Some transactions might not require a PIN, especially if they’re under a certain amount or if the merchant does not support chip and PIN (though this is rare in places like the UK). In such cases, you might just use the chip or the contactless feature of your card if it has one.

What is the difference between EMV and chip and pin?

EMV and “chip and PIN” are terms that are closely related but refer to different aspects of modern card payment security. Here’s a breakdown of the differences:

  1. EMV:
  • Definition: EMV stands for Europay, MasterCard, and Visa, the three companies that originally created the standard.
  • What It Is: EMV refers to a global standard for credit and debit payment cards based on chip card technology. The standard defines the interaction at the physical, electrical, data, and application levels between IC cards (integrated circuit cards, or “chip cards”) and IC card-capable point of transaction terminals.
  • Scope: EMV encompasses both chip and PIN and chip and signature systems. The particular method of verification (PIN, signature, or even none) depends on the card issuer’s preferences and the specific transaction’s circumstances.
  • Security: The primary advantage of EMV over magnetic stripe cards is the increased security against card cloning or skimming. EMV chips generate unique transaction codes for each transaction, rendering stolen transaction data useless for future transactions.
  1. Chip and PIN:
  • Definition: Chip and PIN refers specifically to a type of cardholder verification method used in EMV transactions.
  • What It Is: It’s a system where, during an EMV card transaction, the cardholder must enter a Personal Identification Number (PIN) to authenticate the transaction.
  • Scope: Chip and PIN is just one method of cardholder verification within the broader EMV standard. Other methods include chip and signature or even chip and choice (where the verification method might be decided by the merchant or based on the transaction amount).
  • Security: By requiring a PIN, chip and PIN systems provide an added layer of security, ensuring that even if a card is lost or stolen, it cannot be used for unauthorised transactions without the associated PIN.

In summary, EMV is the broader technical standard for chip-based payment card transactions, while “chip and PIN” specifically describes a type of cardholder verification method used within EMV transactions.

Is chip and PIN safer than contactless?

Both chip and PIN and contactless payment methods offer increased security over traditional magnetic stripe cards, but they serve different purposes and have distinct advantages and potential vulnerabilities. Let’s examine both:

  1. Chip and PIN:
  • Security Advantage: The primary security advantage of chip and PIN is the requirement for the cardholder to enter a Personal Identification Number (PIN) for the transaction to be approved. This means that even if a card is lost or stolen, it would be challenging for a thief to use the card without knowing the PIN.
  • Potential Vulnerability: If a thief manages to obtain both the card and its associated PIN, they could potentially use the card for unauthorised transactions.
  1. Contactless (e.g., NFC – Near Field Communication):
  • Security Advantage: Contactless payments are designed for speed and convenience. They typically have limits on the transaction amount to reduce potential losses (e.g., in the UK, as the limit was £45, but this might change). Each transaction uses encrypted data, and the card never has to leave the owner’s hand, reducing the chance of skimming or visual data theft.
  • Potential Vulnerability: If a contactless card is lost or stolen, it could potentially be used for small unauthorised transactions without needing a PIN or signature. However, the limit on the transaction amount and the cumulative limit (after which a PIN is required) mitigates the potential loss. There are also concerns about electronic pickpocketing, where a malicious actor could use a device to read a contactless card. Still, the actual risk is relatively low, especially since the data obtained this way is often insufficient for meaningful fraud.

So, is chip and PIN safer than contactless?

  • From a strict security standpoint, chip and PIN has the edge because it requires active authentication (the PIN) for every transaction.
  • However, contactless offers a blend of convenience and security that’s more than sufficient for many everyday transactions. The limits on contactless transactions also act as a safety measure.
  • Both methods are significantly safer than traditional magnetic stripe transactions.

Ultimately, the “safest” method depends on the specific context and user preferences. Some people might prioritise the added security of chip and PIN, especially for larger transactions, while others might value the speed and convenience of contactless payments for smaller, everyday purchases.

Can you still swipe a chip card UK?

In the UK, the primary method of using credit and debit cards has shifted from swiping the magnetic stripe to inserting the card for chip (EMV) transactions or tapping for contactless payments. This transition was driven by the need for better security against card fraud, and the UK was an early adopter of the chip and PIN system.

However, while chip and PIN and contactless have become the standard, many chip cards still have a magnetic stripe on the back. The reasons for this include:

  1. Legacy Systems: Some older systems or backup systems might still rely on swiping.
  2. International Compatibility: British travellers might find themselves in countries where chip and PIN or contactless methods are not widely adopted. In these places, the ability to swipe the card can be essential.

That said, in the UK itself, the vast majority of merchants and retailers have moved away from swiping as a primary method of transaction. If you tried to swipe a chip card at most UK terminals, you’d likely be prompted to insert the card for the chip or use the contactless method instead.

In cases where the chip is damaged or unreadable, some terminals might allow a swipe as a fallback, but this is not common and might require additional verification or approval.

What is a disadvantage of using chip and pin?

While chip and PIN systems have significantly enhanced security for card transactions compared to magnetic stripe cards, there are still some disadvantages or challenges associated with their use:

  1. Forgotten PIN: If a cardholder forgets their PIN, they can’t complete a chip and PIN transaction. They might be required to sign instead (if the terminal allows), or the transaction could be declined.
  2. Physical Wear and Tear: The chip on a card can become worn out or damaged with extensive use or rough handling, making the card unreadable in some instances.
  3. Adoption and Infrastructure Costs: For merchants, the transition to chip and PIN terminals can be costly. They might need to purchase new equipment and train staff. While this transition has already taken place in many regions, it was initially a barrier.
  4. Slower Transaction Times: Chip and PIN transactions can be slightly slower than swiping a magnetic stripe card, especially when the user is unfamiliar with the process or if they enter the PIN incorrectly.
  5. Potential for Observation: There’s a risk, albeit small, of someone observing the cardholder enter their PIN and then stealing the card to make unauthorised transactions.
  6. Not Universally Adopted: While many countries have adopted chip and PIN, it’s not universal. For example, in the US, chip and signature is more common, which can lead to confusion for travellers or merchants unfamiliar with the other’s system.
  7. Limited Transaction Value with Offline Transactions: Some chip and PIN transactions are processed offline (the terminal doesn’t immediately connect to the bank to approve the transaction). For these offline transactions, there’s often a limit to the transaction value to mitigate potential risks.
  8. False Sense of Security: Some users might believe that chip and PIN is impervious to fraud or hacking, leading them to let their guard down. While chip and PIN greatly enhances security, no system is entirely immune to all types of threats.

Despite these challenges, the chip and PIN system offers a much more secure alternative to the traditional magnetic stripe cards, significantly reducing particular types of card fraud like card cloning or skimming.

How many times can you use chip and pin in a day?

The number of times you can use chip and PIN in a day isn’t typically limited by the chip and PIN technology itself. However, there may be other limitations or restrictions in place:

  1. Daily Spending Limit: Some banks or card issuers impose a daily spending limit on their cards. Once you reach this limit, you won’t be able to use the card for more transactions until the next day. The daily limit can vary significantly between banks, account types, and whether the card is credit or debit.
  2. Frequency Limitations for Offline Transactions: Some chip and PIN transactions, especially those made in areas with poor connectivity, might be processed offline (the terminal doesn’t immediately connect to the bank to approve the transaction). There could be limitations on the number or cumulative value of offline transactions before an online authorisation is required.
  3. Contactless Limits: While not directly related to chip and PIN, many cards equipped with contactless technology have limitations. For instance, after a certain number of contactless transactions, you might be prompted to perform a chip and PIN transaction to verify your identity.
  4. Security Protocols: If a bank’s fraud detection systems detect unusual or suspicious activity, they might temporarily block the card. Multiple transactions in a short time, high-value transactions, or transactions in different geographical locations can sometimes trigger these security protocols.
  5. ATM Withdrawal Limit: If you’re using the card to withdraw cash from ATMs, most banks have a daily withdrawal limit. This is separate from the point-of-sale transaction limit.

It’s always a good idea to be familiar with your bank or card issuer’s specific policies and limits. If you plan to make many transactions or high-value purchases in a day, notifying your bank in advance can help prevent any potential issues or declined transactions.

How do I know if I have a Chip and PIN card?

Determining if you have a Chip and PIN card is relatively simple. Here’s how you can check:

  1. Look for the Chip: Check the front of your card for a small, gold or silver-coloured square. This is the chip, and it will be slightly raised from the surface of the card. If your card has this chip, it’s equipped with EMV technology, which is the global standard supporting chip and PIN or chip and signature transactions.
  2. Review Mail or Documents from Your Issuer: When banks or card issuers provide a chip card to customers, they typically send information explaining its features and how to use it. This might be in the form of a letter, a pamphlet, or other informational material that came with the card.
  3. Usage Experience: If you’ve used the card at retailers and were prompted to enter a PIN (rather than providing a signature), it’s a Chip and PIN card. If you were asked for a signature, it’s a Chip and Signature card. Some cards can function as both, depending on the merchant or region.
  4. Contact Your Card Issuer: If you’re still uncertain, the most straightforward way to know for sure is to contact your bank or card issuer. They can provide specifics about the features and security measures associated with your card.
  5. Check the Card’s Documentation or Website: Often, the card’s official website or the documentation you received with the card will specify if it’s Chip and PIN, Chip and Signature, or both.

Remember, even if you have a Chip and PIN card, not every transaction will necessarily require a PIN. Some small-value transactions, especially those made using contactless technology, may not require either a PIN or a signature.

Are debit cards Chip and PIN?

Yes, many debit cards around the world use the chip and PIN system, especially in regions where this system has been widely adopted. However, the specific implementation of chip technology on debit cards can vary by country and by the issuing bank or institution.

Here are some general points regarding debit cards and the chip and PIN system:

  1. Europe and the UK: In many European countries and the UK, chip and PIN has been the standard for both credit and debit cards for several years. When making a purchase or withdrawing cash from an ATM with a debit card, users are generally required to enter a PIN.
  2. United States: The adoption of chip technology in the US has been slower compared to Europe. While many debit cards now come with a chip, transactions might be processed as either chip and PIN or chip and signature, depending on the merchant and the card issuer’s preferences. Some US debit cards will prompt for a PIN for debit transactions but offer a signature option for credit transactions (even if it’s still a debit card).
  3. Other Regions: The implementation of chip and PIN technology on debit cards varies widely in other parts of the world. Some countries have fully embraced the system, while others might still rely more on magnetic stripe cards or chip and signature transactions.
  4. ATMs: For security reasons, ATMs generally require a PIN when using a chip-enabled debit card to withdraw money, even in regions where chip and signature is common for in-store transactions.
  5. Contactless: Many modern debit cards also offer contactless payment capabilities. For these transactions, neither a PIN nor a signature is typically required for smaller amounts. However, after a certain number of contactless transactions or once a cumulative spending threshold is reached, the card might prompt the user to enter a PIN for added security.

If you’re unsure about the specific features of your debit card, it’s always a good idea to check with the issuing bank or financial institution. They can provide clarity on whether your card operates under chip and PIN, chip and signature, or both.
