This blank 13.56 MHz RFID/NFC white tag is a compact disc-shaped token commonly used for laundry tracking, garment identification, and asset tagging. It contains a Mifare Classic 1K chip with 1 KB of writable EEPROM storage. The chip and antenna are passively powered — no battery is needed.
The chip stores data in writable EEPROM divided into banks and supports over 100,000 re-write cycles. A permanent 4-byte serial number is factory-burned into each chip for unique identification.

Jargon buster
Plain-language definitions for the technical terms used above.
- EEPROM
- A type of non-volatile memory that keeps stored data even when power is turned off. In a sensor module, it can be used to store settings or calibration data so they do not need to be re-entered every time.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
