GTIN: 5907614660840 · SKU: HD-RD20XC

The HD-RD20XC is a compact, wired 13.56 MHz RFID card and tag reader. It connects to a computer with a USB cable — the system recognises it as an HID keyboard, so no drivers need to be installed. The reader reads tags with chips compatible with MIFARE 1K S50, MIFARE Plus and MIFARE DESFire as well as NTAG213/215/216 from up to 80 mm away and confirms every read with a light and sound signal. It is suited to warehouse inventory, time and attendance, goods registration in retail and access control.
