Programmed ID ring: Built-in pre-programmed T5577 chip. It can be used with an access control device compatible with TK4100, EM4100, or EM4200 ID, but cannot copy other ID tags. Before copying a card, check whether it is encrypted. Copying encrypted cards requires a copier with that capability. Compatibility with encrypted tags may vary by access machine, even when the frequency and protocol are compatible; in this situation, ask the reader supplier to authorize the ring. The T5577 ID ring must first be copied and written before use with an access reader. The programmed ID ring cannot copy other tags. The UID IC ring can be used directly with an access control reader or to copy another access control tag. This is not an NFC ring and cannot be used with a phone
