Abstract: A scanner detection model is created by a detection system to determine whether a laser scanner is present so the user is notified of the potential inability to accurately read a machine-readable identifier on a user device. A user operating the user device accesses an electronic record and a machine-readable identifier that comprises information identifying the electronic record is displayed on the user device. A scanner detection module detects display of the machine-readable identifier and turns on a camera resident on the user device. The camera captures and analyzes images. The scanner detection module identifies whether the scanner is a laser scanner based on an analysis of the images and the scanner detection model created by the detection system. If the scanner is a laser scanner, a message is displayed on the user device indicating that the machine-readable identifier is to be entered or inputted, instead of scanned.
