The ZKTeco UR20RW is a high-frequency USB card reader and writer (card issuer) capable of reading and writing data in the User Area and EPC Area of UHF tags. It works with tags and cards compliant with the EPC Global UHF Class1 Gen 2 and ISO 18000-6C standards.
The device operates via a plug-and-play USB interface — no separate drivers are needed when connecting to a computer. Its built-in control chip includes a watchdog and voltage detection circuit, ensuring stable read performance and reliable operation. Upon a successful read, the device provides an audible tone and LED feedback.
An ideal accessory for card enrollment in access control systems, parking management, and UHF-based asset tracking systems. It integrates directly with a computer, feeding tag data straight into text fields as keystroke input.
