wiki: ingest GEE-QR-ER80 QR access reader datasheet

Browse Source 
The reader on hand is a GEE-QR-ER80 QR/DataMatrix/1D barcode access reader
(not an EM4100 prox-card reader as first guessed). Interfaces: Wiegand 26/34,
RS-232, RS-485, USB, TCP/IP; 4-15 VDC; Linux-supported. Variant on hand: -Q-W
(QR scanner, Wiegand/RS-232/485).

This is the QR-ticket scanner the design already needed: a host-side reader
whose scans become read-bus events consumed by the (already-built) exit flow
and QR-permit path. Prefer RS-232/485 over Wiegand (Wiegand can't carry a
variable-length QR string; autonomy is moot with the no-ACL Dingtian).

New source + entity pages; updated ticket-encoding, entry-exit-readers, index.
Open (blocks the adapter): the RS-232/485 frame + baud (ASCII CR/LF expected).

## [2026-06-16] ingest | GEE-QR-ER80 QR access reader datasheet
- User has the reader; ingested `raw/GEE-QR-ER80 QR Code Access Control Reader.pdf`.
- CORRECTION: earlier guessed "ER80-EM" = a 125 kHz EM4100 prox-card reader. WRONG — the datasheet
shows **GEE-QR-ER80**, a **QR / DataMatrix / 1D barcode** optical access reader (optional ID/IC
card). It's the [[ticket-encoding|QR ticket]] scanner the design already needed, not a card reader.
- Specs: interfaces Wiegand 26/34 · RS-232 · RS-485 · USB · TCP/IP; 4–15 VDC <800 mA; 360°;
Windows + **Linux**; wiring VCC/GND/D0/D1/TX(R+)/RX(R-)/LED/BEEP. On hand: **`-Q-W`** (QR scanner;
Wiegand/RS-232/RS-485).
- Fit: host-side reader → a serial `ReaderDevice` adapter emitting `read` events → consumed by the
already-built exit flow + QR-permit path. Prefer RS-232/485 (serial) over Wiegand (Wiegand can't
carry variable-length QR; autonomy moot since [[dingtian-relay]] has no onboard ACL).
- New: source [[gee-qr-er80]] summary + entity [[gee-qr-er80]]. Updated [[ticket-encoding]],
[[entry-exit-readers]], [[index]].
- OPEN (blocks the adapter): the RS-232/485 **frame + baud** — is a QR scan an ASCII CR/LF string
(expected) or framed? Datasheet omits it; resolve via vendor docs or by observing the port.
