Contactless cards are the perfect payment method for any individual on the go. Contactless card machines are becoming more popular not just because of the convenience they offer, but also because of how securely they can be used. To make transactions easy, you can also visit https://www.cutpay.co.uk/payment-solutions/mobile-terminals/ to buy a contactless card machine.
Before you can use a contactless card machine, you need to understand how it works. Here are four key things to remember:
1) The contactless card machine requires a nearby NFC (near-field communication) reader in order to work. If the reader is not present, you will not be able to use the machine.
2) Once you have inserted your contactless card into the machine and activated it by pressing the "start" button, you will be prompted to enter your PIN code. After entering your PIN code, you will be able to use the machine as usual.
3) When making a purchase, always scan the barcode on the product before selecting it. This will allow the machine to automatically charge your contactless card for that purchase.
4) Always keep your contactless card safe and secret – do not leave it unprotected in view of others or stored on public display surfaces.
How a contactless credit or debit card works
When you enter your PIN at a contactless card machine, you are using near-field communication (NFC). Near-field communication is a wireless technology that allows two devices to communicate with each other within a few centimeters. This technology is used in many places, including in payment terminals and contactless cards.
NFC works by sending small amounts of energy between the two devices. When you place your card against the machine, the computer recognizes the chip on the card and automatically processes the transaction.
