Understanding RFID Wiegand Readers

What Is an RFID Wiegand Reader?

An RFID Wiegand Reader is a device that reads and transmits data from RFID tags using the Wiegand protocol—a standard method of transferring data between access control readers and host systems. These readers create an electromagnetic field that powers passive RFID tags. When a tag comes within range, it sends its unique ID to the reader, which then passes it to the access control system.

How Does It Work?

  • The reader emits an electromagnetic signal.
  • The RFID tag, powered by this signal, transmits its UID (Unique Identifier).
  • The reader decodes the UID.
  • The UID is sent to the access control system via the Wiegand protocol (typically 26-bit or 34-bit).

This contactless process allows for seamless, hygienic, and secure access.
