# Source: GEE-QR-ER80 QR Code Access Control Reader (datasheet)

Vendor datasheet (GEE NFC LIMITED, ©2007–2019) for the **GEE-QR-ER80** — a static
**QR-code access-control reader**, optional ID/IC card. The reader the project has
on hand for the [[ticket-encoding|QR ticket]] path. Raw:
`raw/GEE-QR-ER80 QR Code Access Control Reader.pdf` (3 pages). Entity: [[gee-qr-er80]].

## Key takeaways

- **Optical scanner**, not a prox-card reader: reads **QR, DataMatrix, 1D barcode** (static).
  Optional add-ons for **IC card UID / ID card**.
- **Multi-interface:** **Wiegand 26/34, RS-232, RS-485, USB, TCP/IP** — selectable by variant.
- **Power:** 4–15 VDC, < 800 mA. **Read direction:** 360°. Built-in scanner LED.
- **OS:** Windows XP/7/8/10 **and Linux** (explicit) — fits the [[disk-os-hardening|Linux appliance]].
- **Wiring (Wiegand/RS-232/485 variant):** VCC(+12V), GND, **D0/D1** (Wiegand), **TX/R+ , RX/R-**
  (RS-232 / RS-485), plus **LED** and **BEEP** control lines (host can drive feedback).
- **Order code** `GEE-QR-ER80-<scanner>-<interface>`: `Q`=QR scanner / `D`=ID reader / `C`=IC reader;
  `W`=WG·RS232·RS485 / `U`=USB / `T`=RJ45 (TCP/IP). **On hand: `-Q-W`** (QR scanner; Wiegand/RS-232/RS-485).

## Section map

- p1 — overview, physical + feature table (interfaces, power, read direction).
- p2 — supported types (QR/DM/1D + optional IC/ID), OS, environment; **wire definition** (pin table).
- p3 — order-code breakdown, applications (access control / vacation rentals / time attendance).

## Not in this datasheet (open)

- The **RS-232/RS-485 data protocol**: baud rate, frame format, and whether a QR scan is emitted as
  an **ASCII string** (expected) vs. some framed protocol. Decides the host-side adapter — see
  [[gee-qr-er80]] open questions. Resolve by vendor docs or by observing the port on a scan.
