Card machines (also called card terminals) are electronic devices that enable businesses to accept payments made with credit or debit cards.
Card machines were originally called PDQ machines when first introduced in the UK. Regardless of the terminology—be it card machines, card terminals, card readers, Chip and PIN, or PDQ machines—they all have the same purpose: to process card payments
Why does your business need a card machine?
In the UK, according to a recent survey, there are around 2.2 million card readers. This number indicates that more people are moving away from cash and prefer to pay with cards.

When you expand your business to meet the needs of more people, your brand is deemed trustworthy, which also gives you an advantage over other businesses in the same industry.

How does a credit card machine work?
Let’s take a look at how a credit card machine works step-by-step:
1. Initiating the transaction process
The merchant inputs the sale amount into the card machine, initiating the transaction process.
2 - Card presentation by the customer
The customer makes a contactless payment or use their card. For a quick, contactless payment, they simply tap their card on the machine, and for transactions requiring more security, they insert their card and enter their PIN.
3 - Secure communication
The chip on the customer’s card communicates with the machine, which encrypts and sends the transaction details to the merchant’s bank.
4 - Requesting approval
The merchant’s bank sends an authorisation request to the customer’s credit card network, which, in turn, seeks authorisation from the customer’s bank.
5 - Transaction verification
The credit card network verifies the card details and requests the customer’s bank to confirm the availability of sufficient funds or credit.
6 - Transaction completion
Upon successful authorisation, the machine notifies the merchant of a successful payment. Receipt printer prints our a receipt as proof of payment.
