A normal QR Code read will appear in SAFR SCAN Web Console Live tab or SAFR Desktop Events Window.

Following actions can be taken to investigate issues with reading a QR code

From SAFR SCAN event, click “Add card serial number” or “Enroll as new…”

You will be presented with a screen like below where you can read the value that was sent:

Open SAFR SCAN Web Console Logging and view output as QR Code is presented

1. Go to SAFR SCAN Web Console and log in
2. Add “&debug=1” to the URL and reload
3. Click on the “Logs” tab and view the logs in “SAFR Feed”

Log output will look like this:

2024-Jun-03 22:43:11.703680: INFO/accessCredential(547674322592): Construct cardDataOut for format RFID-ISO14443-A-32-Bit, accessCardId=12345, accessFacilityId=123

2024-Jun-03 22:43:11.704393: INFO/accessCredential(547674322592): sendCardDataOut(): Sending out 32 bits of RFID-ISO14443-A-32-Bit card data to wiegand-out...OK
2024-Jun-03 22:43:11.704573: INFO/accessCredential(547674322592): sendCardDataOut(): Sending out 32 bits of RFID-ISO14443-A-32-Bit card data to OSDP-PD-out...OK

Notice that this is similar to log output for reading a card. That is because SAFR SCAN treats reading QR code just like reading an access card.
