Product Description

This is a blank MiFare Classic 'laundry' tag - often used for laundry or identification but also found in other systems where a small proximity card is desired. This one is clear! The tag contains a NXP S50 chip and an antenna, and is passively powered by the reader/writer when placed a couple inches away. 

These can be read by almost any 13.56MHz RFID/NFC reader but make sure it can handle MiFare cards as there are a few other encoding standards (like FeLica) They are tested and work great with the Adafruit NFC/RFID Shield for Arduino

These chips can be written to & store up to 1 KB of data in writable EEPROM divided into banks, and can handle over 100,000 re-writes. You can use the Adafruit NFC/RFID Shield for Arduino to read and write data to the EEPROM inside the tag. There is also a permanent 4-byte ID burned into the chip that you can use to identify one tag from another - the ID number cannot be changed.
