The QR reader is a push device and the setup wizard assigns random-UUID ids, so
'id = serial' can't be set via the UI. Add a dedicated gee-qr-reader driver
(reader category) with a single 'serial' config field; the admin assigns it
normally and enters the device's serial (its cjihao).
The QR endpoint now resolves the lane by matching lane_devices.config.serial to
the scan's cjihao (instead of row id == cjihao), so no DB hand-editing. An
unassigned serial resolves to no lane -> status:0, gracefully.
Verified via inject through the real /api/setup/assign: assign {serial:
H05M2AFA} -> .jsp scan with a matching permit QR -> status:1 (accept) + open;
re-scan -> permit exit; unknown card -> status:0; unassigned serial -> status:0.
Hardware capture: the GEE/Fondvision reader (serial H05M2AFA) scans + sends +
beeps fine — the earlier 'no beep' was just nothing answering :3000. Real
request: GET /qa/mcardsea.jsp?cardid=...&cjihao=H05M2AFA&... — the 'server
language' setting (JSP here) selects the URL EXTENSION, so it posts .jsp, not
.php. Our route was .php-only and would have 404'd it.
Register the endpoint at php/jsp/asp/aspx/cgi so it works whatever the device is
configured to. cjihao (serial) is the lane key: assign the reader as
lane_devices.id = its serial.
The reader HTTP-GETs on each scan and beeps/acts on our JSON reply (host-in-the-
loop, synchronous). New route GET/POST /qa/mcardsea.php parses the SDK query,
runs the scan through the read dispatcher (permit match -> permit flow; else
transient exit), and replies the SDK verdict: status 1=valid (beep 2x) /
0=invalid (beep 1x), output, time-sync.
Refactored the read flows to return a ReadOutcome {accepted, direction, reason}
so the reply reflects the real accept/reject decision (ReadDispatcher.dispatch,
ExitFlow.handleAt, PermitFlow.run). Fire-and-forget readers ignore it.
Reader's lane is keyed off its serial (cjihao) as lane_devices.id for now;
endpoint is public (reader has no auth, on the device subnet).
Verified via inject: valid permit QR -> status:1 + open; re-scan -> permit exit;
unknown QR -> status:0; barrier-less lane -> status:0.
The QRCode SDK v1.6.5 settles the reader protocol (supersedes the earlier
serial guess). On each scan the reader HTTP-GETs the host
(/qa/mcardsea.php?cardid&mjihao&cjihao&status&time); the host replies JSON
{data:[{...,status,output}],code:0}. Reply status 1=valid(beep 2x)/0=invalid
(beep 1x); output 0=Access/1=WG26/2=WG34; time syncs the clock. The GET's status
low digit is the direction (1=in/0=out).
Key: the beep/accept is decided by the SERVER REPLY, not locally -- the 'no
beep' during bring-up was a plain-text reply, not a scan failure. Host-in-the-
loop and synchronous. 'Server language' only selects the URL path; transport is
plain HTTP.
New source page qrcode-sdk; updated gee-qr-er80 (protocol resolved), index.
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).
