RFID Read-Write Module Cost
YHY502CTG is a compact 13.56MHz RFID Read-Write module designed for ISO14443A standard and supports Mifare® Classic 1K, Mifare® Classic 4K transponders. It is controlled by external device over UART with simple protocols defined in this sheet. YHY502CTG can be easily and quickly integrated into RFID applications with very less effort.
Mifare® Classic is a secure memory (1Kbyte, 4KByte) chip/card often called contact-less smart card. The reason it is called smartcard is because it has increment and decrement functions designed for especially payment systems. Mifare® Classic family of tags is being used in RFID applications where very high security and fast data collection systems are required. This family of tags has contactless communication speed up to 106 KHz and uses very strong encryption techniques. If the user want to copy or modify the content of the Mifare®Classic family of tags then he needs the correct key(s) when it is protected. As a result Mifare® become ideal for e-money applications, secure access, data storage and fast data collection systems. Not only limited with these applications but printed antenna technology makes possible to find very thin and low cost Mifare® tags (e.g. labels,stickers) so that extending the field of RFID applications.
