Anyway want to recommend bluetooth barcode readers, or cases with integrated bar code readers, for use with FMGo?
For batch scanning, I like the ScanFob, which my client purchased through https://www.zerobluetech.com AgnesB.Riley's company.
FMGo can do one-ups with its camera of course.
Consider how the hardware will be used (and abused!), to help you choose.
Barcode scanners cannot operated directly from FileMaker Go. Instead we connect Bluetooth scanners as keyboard. Most iOS ready scanners have keyboard mode for connection. In that case, one field should be active to enter code after reading. When BT keyboard is connected, iOS hides keyboard. So needed to hold long press every time to show screen keyboard. Some scanners like Socket has another button to show/hide screen keyboards. I recommend using laser model, for QR code device's camera is enough.
I hope this could help,
