## Description

This blank 13.56 MHz RFID/NFC silicone bracelet contains a Mifare Classic 1K chip with 1 KB of writable EEPROM storage. The embedded chip and antenna are passively powered — no battery is needed. Simply hold the bracelet a few centimetres from a compatible 13.56 MHz RFID/NFC reader to read or write data. 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. Key Features 1 KB Writable EEPROM – Divided into banks, supports 100,000+ write cycles Permanent 4-Byte UID – Factory-burned unique ID for identification (cannot be changed) Silicone Wristband – Comfortable, waterproof form factor suitable for wearable applications Passive Operation – No battery required; powered by the reader's RF field ISO/IEC 14443 Type A – Compatible with standard 13.56 MHz RFID readers Specifications Frequency – 13.56 MHz Chip – Mifare Classic 1K (ISO/IEC 14443 Type A) Memory – 1 KB writable EEPROM Write Endurance – 100,000+ cycles UID – 4-byte permanent serial number Form Factor – Silicone bracelet Ideal For Access control and event identification Attendance tracking systems RFID reader/writer prototyping and testing Wearable identification projects Package Contents 1× RFID/NFC Silicone Bracelet (1 KB) Note: This bracelet uses the Mifare Classic chipset (ISO/IEC 14443 Type A). Since approximately 2014, the NFC Forum no longer supports this chipset, so most newer smartphones cannot read or write to it. This only affects phone/tablet use — dedicated RFID readers (such as PN532-based boards) work without issue.
