What technology is commonly associated with contactless payments?

Contactless payments primarily rely on Radio Frequency technology. This technology utilizes radio waves to facilitate secure communication between a payment terminal and a contactless card or mobile device equipped with Near Field Communication (NFC). When a user taps their contactless payment card or mobile device near a terminal, the embedded chip within the card or device transmits payment information through these radio waves.

This method is widely adopted for its convenience and speed in processing transactions, allowing for quick payments without the need for physical contact or swiping. The use of Radio Frequency technology also enhances security features, as the transmission is short-range and encrypted, minimizing the risk of unauthorized access to sensitive payment data.
