How to Handle EMV Chip Transactions With A Credit Card Machine?

19 minutes read

When processing EMV chip transactions with a credit card machine, it is important to first make sure that the machine is equipped to accept chip cards. When the customer inserts their chip card into the machine, it will prompt them to leave the card in the slot until the transaction is complete. The machine will then communicate with the card's chip to validate the transaction securely. It is important to follow the prompts on the screen and wait for the transaction to be approved before removing the card. If the transaction is declined, you may need to ask the customer for an alternative payment method. It is also important to ensure that the card is inserted into the machine with the chip facing up and towards the slot. Following these steps will help ensure a smooth and secure EMV chip transaction process.

What is the encryption process for EMV chip transactions?

The encryption process for EMV chip transactions involves several steps:

  1. The terminal reads the chip on the credit or debit card and retrieves the card's encrypted data.
  2. The terminal generates a random number called the Application Transaction Counter (ATC) and combines it with other transaction-specific data.
  3. The terminal sends this data to the card for approval. The card uses its private key to decrypt the data and verify the authenticity of the terminal.
  4. The card generates a cryptogram, which is a one-time code that is unique to the specific transaction. The cryptogram is encrypted using the card's private key.
  5. The card sends the cryptogram back to the terminal, which uses the card's public key to decrypt and verify the cryptogram. This helps ensure that the card has not been tampered with or duplicated.
  6. The terminal communicates the transaction details, including the cryptogram, to the payment network for authorization.
  7. The payment network verifies the cryptogram and authorizes the transaction.


By using encryption and cryptograms, EMV chip transactions are more secure than traditional magnetic stripe transactions.


What is the PIN entry process for EMV chip transactions?

  1. Insert the chip card into the EMV card reader with the chip facing up.
  2. Follow the prompts on the screen to verify the transaction amount.
  3. The terminal will prompt you to enter your personal identification number (PIN) using the keypad on the card reader.
  4. Enter your PIN and press the 'Enter' or 'OK' button.
  5. Wait for the terminal to process the transaction and display a confirmation message on the screen.
  6. Remove your card from the terminal once the transaction is completed.
  7. Remember to take your receipt, if offered, and any other items such as cash back or the card itself.


What is the role of the card issuer in EMV chip transactions?

The role of the card issuer in EMV chip transactions is to provide the cardholder with a secure payment card that contains an embedded EMV chip. The card issuer is responsible for issuing the card, managing the cardholder's account, and authorizing transactions. When a cardholder uses their EMV chip card to make a payment, the card issuer validates the transaction, verifies the cardholder's identity, and approves or declines the transaction based on a number of factors including the cardholder's available balance, spending patterns, and previous transactions. The card issuer also plays a key role in protecting cardholder data and preventing fraud by implementing security measures such as encryption, tokenization, and two-factor authentication.


What is an EMV chip on a credit card?

An EMV chip is a small microchip embedded in credit and debit cards that provides an added layer of security when making transactions. EMV stands for Europay, MasterCard, and Visa, the three companies that originally developed the technology. The chip creates a unique code for each transaction, making it more difficult for fraudsters to clone the card or steal sensitive information. EMV chip cards are more secure than traditional magnetic stripe cards and are widely used around the world.


How to protect the EMV chip on a credit card?

  1. Keep your card in a protective sleeve or wallet designed to block RFID signals. This will help prevent unauthorized scanning of your card's information.
  2. Avoid exposing your card to extreme temperatures, as this can damage the chip.
  3. Never bend or scratch the EMV chip on your card, as this can cause it to malfunction.
  4. Be cautious when using ATMs or card readers in public places, as these devices can be tampered with to steal your card information. Look for signs of tampering before inserting your card.
  5. Regularly monitor your account statements and report any suspicious activity to your card issuer immediately.
  6. If your card is lost or stolen, contact your card issuer right away to have the card canceled and replaced.
  7. Consider using alternative payment methods such as mobile wallets or virtual credit card numbers for online transactions to reduce the risk of exposing your physical card to potential fraud.
