To scan your tickets with an External USB Laser Scanner your scanner should support 2D (QR Code) barcode symbology.
The scanner has a viewfinder that projects a bright red laser that corresponds to the scanner’s vertical field of view. While scanning a QR Code the laser can be positioned in any direction for a good read. It can be positioned vertically, horizontally or even diagonally.
2D Matrix symbol (QR Code)
The laser is smaller when the scanner is closer to the code and larger when it is farther from the code. Symbology with smaller bars or elements should be read closer to the unit. Symbology with larger bars or elements should be read farther from the unit. To read single or multiple symbols (on a page or on an object), hold the scanner at an appropriate distance from the target, pull the trigger, and center the laser on the symbol.
You will be able to see the scan option only after the limits that you set for ‘Start Scan Time’ while creating the event has been triggered.
Only users who have permissions to Scan the Tickets will be allowed to scan. The permissions can be changed only by the owner.
The External USB Laser Scanner allows you to only scan your tickets; you will not be able to un-scan a ticket using the External USB scanner. To un-scan a ticket you need to either use the manual scan OR the YouScan application.
