The Bioteknix U11‑D UHF Card Issuer operates using Ultra High Frequency (UHF) RFID technology for wireless identification and card issuance. It works in the 902–928 MHz frequency range and follows EPCglobal Class 1 Gen 2 and ISO 18000‑6C standards. When a UHF card is placed near the reader, the device emits electromagnetic waves via its integrated antenna, energizing the passive card, which then transmits its unique ID back to the reader. The Bioteknix U11‑D processes this signal and sends the data to a host system through a USB interface or optional Wiegand output. Acting as a plug-and-play device, it functions like an analog keyboard, automatically entering card information into computers or access control systems. With fast response, reliable performance, and long-range reading, the Bioteknix U11‑D is ideal for access control, card issuing, asset tracking, parking management, and identification applications.
