After updating an iOS device to version 10 or above, when scanning a ticket it will only scan the first digit in Altru or scans the number but doesn't validate. If you go to note pad, it scans all numbers just fine.
Our Product Engineers have determined this issue also occurs outside of Altru. Therefore, we recommend to reduce the scanner speed and work with the scanner manufacturer. Alternatively, you can use Android and Windows devices.
