How does PIN on glass work?
PIN on glass refers to PIN entry on an integrated touchscreen of a PCI-approved smart terminal. In this case, a physical PIN pad is not present on the card machine, so the touchscreen displays a virtual PIN pad when prompted to enter the code.
Some card terminals may have both a physical PIN pad and touchscreen display, in which case the dedicated keypad would be used for PIN entry.
Entering a PIN on a touchscreen is not considered much different than ‘PIN on terminal’ which is the definition for entering PINs on a physical keypad of a terminal. Why? Because whether PIN entry happens on a touchscreen or keypad, as long as it is done on the same PCI-certified terminal that reads the credit or debit card, the payment process happens the same following way:
- The card is read electronically in the terminal via chip, contactless or swipe.
- When relevant, the terminal will prompt the payer to enter their PIN on the keypad or touchscreen.
- Both the electronic card data and PIN are securely transmitted to the payment processor and card issuer for verification.
- When the card issuer has verified this information, the terminal receives this confirmation and completes the transaction.
In this scenario, the secure transmission of all the relevant card data is handled solely by the card terminal.
