    13.56MHz RFID Card Tag ID Door Entry Access NFC 13.56 MHz 13.56M Hz Arduino PIC

    + This is a basic RFID tag that functions within the MIFARE Classic 1K guidelines. You can use these for all sorts of identification and sensing applications. The tag also has 1K of data storage which can be read and written from a compatible device.

    + The MIFARE Classic card is fundamentally just a memory storage device, where the memory is divided into segments and blocks with simple security mechanisms for access control. They are ASIC based and have limited computational power. Thanks to their reliability and low cost, these tags are widely used for electronic wallet, access control, corporate ID cards, transportation or stadium ticketing.

    About MIFARE Classic 1K

    + The MIFARE Classic with 1K memory offers 1,024 bytes of data storage, split into 16 sectors; each sector is protected by two different keys, called A and B. Each key can be programmed to allow operations such as reading, writing, increasing value blocks, etc. 16 bytes per sector are reserved for the keys and access conditions and can not normally be used for user data. Also, the very first 16 bytes contain the serial number of the card and certain other manufacturer data and are read only. That brings the net storage capacity of these cards down to 752 bytes for MIFARE Classic with 1K memory.
