POS Pin Pad

POS Pin Pad

As POS technology is embraced by every sector on the globe, companies are becoming more aware of the fact that the system is comprised of many components.

Recent research indicates that 36 percent of businesses (1) regard hardware improvements to be a high priority. Starting with making sure you have the proper PIN pad incorporated into your system, you may proceed.


An electronic device that accepts and encrypts a cardholder’s personal identification number (PIN) during a debit, credit, or smart card-based transaction is known as a PIN pad or PIN input device, or PED for short (PIN).

PIN pads are often used in conjunction with payment terminals, ATMs or integrated POS devices, wherein an electronic cash register is accountable for collecting the exact transaction quantity  and facilitating the transaction, rather than a physical cash register.

The PIN pad is needed in order to recognise the card and to enable the PIN to be typed securely and encrypted well before the card information is transmitted to the financial institution. If you use chip cards, you may find that the PIN is simply transmitted from your PIN pad to your chip card, and that it is then confirmed by the chip card. If the PIN is not transmitted to the bank or card scheme for verification, there is no need to send it elsewhere. (This is referred to as “offline PIN verification” in the industry.

If someone attempts to tamper with the device, the encryption keys and the PIN will be deleted, just as they are with certain stand-alone point-of-sale systems. The PIN is encrypted instantaneously upon input, and a PIN block with the encrypted PIN is generated. As soon as the encrypted PIN block has been sent from the PIN pad to the connected POS machine and / or the chip card, it is automatically deleted. PINs are encrypted using a number of encryption methods, the most prevalent of which is triple DES in 2022, according to the NIST Cybersecurity Framework.

When it comes to PIN pads, they must be authorized in accordance with the standards established by the payment card industry to guarantee that they offer sufficient security at the time of PIN input as well as throughout the PIN encryption process. ISO 9564 is an international standard for PIN management and security that defines certain necessary and recommended features of PIN entry devices, as well as some additional requirements and recommendations.

Although PIN pads are designed to enable the input of numeric values, certain PIN pads include letters allocated to the majority of the digits, allowing the use of alphabetic characters or phrases as a mnemonic for the numeric PIN to be used instead of numbers. Not all PIN pads have the same letters for the same numbers, and not all PIN pads have the same size. There is no specific letter assignment mandated by ISO 9564, and the standard provides two instances that vary in the numbers to which the letters Q and Z are allocated.


What is a POS PIN Pad?

Top POS Pin Pads

PIN pads are electronic devices that form a critical component to a point of sale structure. They are used in debit and credit transactions and are convenient for consumers who don’t carry cash. PIN pads have both software and hardware capabilities to erase the security keys and PIN numbers immediately. This helps secure the data in the event someone tampers with the device.

There are a few different types of PIN pads you can purchase depending on your business needs. The simplest form only allows for PIN entry. There is no credit card swipe.

Signature capture PIN pads enable people to not only swipe their credit cards but sign their name electronically. These are the types you see at a grocery store or in retail. This PIN hardware helps prevent chargebacks. The digital screens where people sign can also project video ads when not being used. They have multi-function capabilities for digital signage.

Why do You Need a PIN Pad?

What is a POS PIN Pad?

One of the most beneficial reasons for having a PIN pad is to reduce fees. This is because debit transactions are generally cheaper than credit transactions. Debit transactions charge a flat fee while credit card fees are based on a total transaction amount. However, there are no set rules since the merchant service provider always has the ultimate say on fees.

PIN pads also speed up transactions and reduce fraud. There is no need for the cashier to touch a customer’s card. The customer has total control over the experience and exchange.

Frequently Asked Questions

What type of pinpads exist?

The most basic pinpad does not include a credit card swipe and only allows for PIN entry.

Signature capture pinpads allow customers to swipe credit cards on the pinpad as well as sign their name electronically, like the pinpad at your local grocery store. Signed receipts can help prevent chargebacks. These pinpads can also project advertisements or videos on their digital screens when they are not being used.

What about EMV, NFC, and Apple Pay?

Regardless of the technology, most new and developing payment technologies require pinpads.

Can I use any pinpad with my POS system?

No, pinpads must be encrypted with the merchant’s payment processor, and they are typically designed for specific software programs. That’s why it’s always helpful to speak with a POS specialist before purchasing your pinpad.

Choosing Your POS PIN Pad

The cost to own and operate a point of sale system can vary by hundreds of factors. Some brands offer the hardware in bundle packages, but most will sell you pieces a la carte. That means, you can run into issues when it comes time to integrate your technology.

When looking for a PIN pad that aligns with your operations, it’s helpful to ask questions like:

  • Do I want paper receipts or an electronic signature?
  • Do I need a touchscreen or is a normal display ok?
  • How many types of ways do my customers pay?
  • Am I looking to promote or run ads through a PIN pad?
  • Do I need to run a loyalty program at checkout?

The answers to these questions should help you know where to start. It’s always important to research each product thoroughly. Some come with hidden fees or lack equipment for complete setup. Once you’ve got your eyes on the prize, installation should be a snap!

Recommended Readings

We have compared Fattmerchant vs Square, thinking that they were very similar POS and payment processors, but we found many differences and we were surprised by these findings.

Complex industries that handle their own inventory and 3PL organizations have granular requirements about batch recalls, warehouse management and inventory reconciliation. They need handheld inventory scanners that connect in real time with their point of sales systems and ERPs. We review them here and test them connecting to a Zebra printer. Beautiful!

We have reviewed several POS providers. The most interesting according to their industry vertical are: OVVI POS, NCR Counterpoint, Alexandria POS Maid, Verifone Ruby 2 POS, Mynt POS, Indica Online, Reverse, Micros, 1st Pay, Simphony, and Appetize.

There is a type of POS that the majority of readers here do not seem to like. I refer to the POS Pin Pad type. I understand the readers that reject them, but we can recommend it for some type of businesses, as you will read.

Each industry vertical requires a different type of POS, so we cannot analyze them all together in one single group. Therefore, we have researched in different verticals to define which are the POS systems that we can recommend for each industry and why: Wholesale POS, POS for kiosks, fast foods, POS for restaurants and which of them work well in iPads because some work very bad in mobile systems in my opinion, gas stations, supermarkets, dispensaries, convenience stores, dry cleaning industries, furniture, liquor stores, and bike shops.

What about cash registers? We have reviewed some and we have found good and bad products: cash registers for gas stations, small businesses in general, and restaurants.

We reviewed some specific type of point of sale systems that determine the price according to the weight, called POS scales.

We have studied barcode and label printers, as label printing is a legal requirement in some industries

Restaurants, fast foods, delis and food trucks, require a separate kitchen printer integrated with the POS with a separate hardware unit. We have reviewed them here.

We do not usually review printers for POS, we simply dedicate ourselves to review a complete POS system with its hardware. However, we had so much criticism and discussions around printers for Square, that I have decided to investigate further here.
