INQUIRY

125kHz Read-Only TK4100 Labels are passive RFID tags operating at the low-frequency (LF) band. Pre-programmed with a unique, factory-locked 64-bit ID (UID), they offer simple identification with no writable memory. Commonly used as disposable access keys, inventory tags, or animal tracking labels, these durable, adhesive stickers provide basic, cost-effective tracking. Compatible with most 125kHz readers (EM4100 protocol), they are ideal for applications requiring only a fixed identifier, like basic entry systems, asset management, or laundry tags.
Note: Their read-only nature prevents reprogramming, and the UID can be vulnerable to cloning in security-critical uses.
