A pin pad is used by people who are deaf or hard of hearing. It has small buttons that you can press to hear the message being displayed on the computer screen. You can also configure a pin pad to operate as a keyboard. This blog post discusses what a pin pad is, how it works, and how you can use one.
What is a PIN Pad?
A PIN pad, also known as a personal identification number keypad, is an electronic keypad that allows cardholders to input their four-digit PINs while using their debit or credit cards.
PIN pads have become a standard fixture at most large shop checkout counters as more consumers use credit cards rather than cash or checks. The payment card industry has supplied these cards with a personal identification number (PIN) necessary to further defend against fraud.
How Does A PIN Pad Work?
After swiping a credit card at a register, the buyer must enter their personal identification number (PIN) into a PIN pad to complete the transaction.
Most current payment cards have an integrated circuit chip that was created in response to the payment card industry’s high security criteria.
Credit cards with integrated microchips, sometimes known as “smart” cards, are another term for them. When a PIN is entered, the chip scrambles it so that unauthorized individuals cannot read it.
Roles Of A PIN Pad
There are two ways to communicate PINs and account information using a PIN pad. Some POS machines send an encrypted PIN to a bank’s automated information management system.
Some PIN pads just transmit the number to an internal recognition chip. This alternate method is known as offline pin verification since the PIN is not transferred to an external system linked to a bank.
Understanding A PIN Pad
The designers of the software used for electronic sales transactions, such as those completed using a PIN pad, have prioritized safety precautions. With each incorrect entry, the number of times a consumer may enter their PIN onto a PIN pad before their card is denied diminishes.
This precaution is the first line of defense against card fraud. Furthermore, PIN pads are manufactured with security coding that deletes any records of entered numbers if thieves attempt to download the data from the PIN pads or hack into them in any other manner.
By far the most used kind of encryption for PIN pads is the Triple Data Encryption Algorithm (DEA). When a PIN is entered, it is processed through the cipher three times, converting the numbers into random characters that even the most determined hackers would find difficult to understand.
The Triple DEA complies with the ISO PIN pad security specifications established by the credit card industry.
When a debit, credit, or smart card is used in a transaction, the cardholder’s personal identification number (PIN) is typed into a PIN pad or PIN entry device (PED) (PIN).
PIN pads are most typically used with electronic cash registers, ATMs, or other payment terminals where the sale amount is input and processed by the machine.
PIN pads, like certain standalone POS terminals, include built-in hardware and software protections that delete the device’s memory and encryption keys if they are tampered with, therefore securing the user’s private information.
While the majority of PIN pads accept only numeric values, others assign letters to the majority of the digits to simplify the use of alphanumeric characters or phrases as a mnemonic for the numeric PIN.
However, not all PIN pads utilize the same number letters. ISO 9564 does not require letter ordering and includes two scenarios in which Q and Z are assigned distinct number values.
