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.

## Description

This is a blank MiFare Classic 1K sticker - 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 both our [PN522 NFC/RFID breakout board](Mifare-RC522-Kit) and [NFC/RFID Shield for Raspberry Pi](NFC-Module-for-Raspberry-Pi)!

**These chips can be written to** amp; store up to 1 KB of data in writable EEPROM divided into banks, and can handle over 100,000 re-writ's. You can use our [PN532 NFC/RFID breakout board](Mifare-RC522-Kit) or [NFC/RFID Shield for Raspberry Pi](NFC-Module-for-Raspberry-Pi)**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.

- 1 KiloByte (8 KiloBit) non-volatile EEPROM storage
- Built in encryption engine with 48-bit key
