RFID keychains, keychain cards, contactless keychains

Introduction to RFID keychains
Keychains are also called keychains, though they are also called by other names. RFID keychains are made by pressing a keychain model from ABS material through high-quality hardware molds, then placing copper wire COB into the mold, and then using ultrasonic technology to assemble it, resulting in the keychains we commonly use for access control. Keychains are compact and easy to carry, making them very suitable for all-in-one card payments. For community life, simply hang the keychain on the keychain and spend without carrying a wallet. Recharges, balance checks, consumption records, and other operations can all be done online, making it very convenient. The keychain features exceptional anti-interference capability, a compact size, and a recognition distance twice that of similar products. Users can customize standard data reading and writing, making specialized application systems more efficient, with a reading range of up to 6 meters. Key tag 96-bit memory capacity, the world's only 64-bit ID number, ultra-wide operation.
