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. 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 both our PN532 NFC/RFID breakout board and

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 our PN532

NFC/RFID breakout board or 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.

These use the S50 chipset, which used to be the 'classic' NFC chipset. In ~2014, the

NFC forum decided not to support this chipset anymore, so newer phones do not

support the MiFare classic. This only matters if you're trying to use this tag with a

phone/tablet.
