Scan any card with the scanner (the card does not have to be attached to a member record).
If the message “Unknown Scan: ‘XYZ’” should appear, it indicates that GateKeeper has detected the card scan but cannot identify the member attached to that barcode number.
If either “Unknown Scan: ‘XXXX’” or a member record shows up after the scan, your scanner is setup and working properly.
If GateKeeper is not seeing your card scans please refer to the Troubleshooting section of the GateKeeper documentation.
