13.56MHz Card

A 13.56 MHz card is a contactless smart card that uses RFID technology and operates at a frequency of 13.56 megahertz (MHz). The card contains an embedded chip and antenna that can wirelessly transmit and receive data when brought close to an RFID reader. Unlike contact cards, 13.56 MHz cards do not require physical contact with the reader. They operate over short distances, typically a few centimeters at most. These cards are used in various applications, including access control, payment systems, and identification.
