Hello, i just arrive on Glide and i was looking for this feature also to See if it’s possible.
You can use Niko Keyboard, it’s an Android app Which allow you to scan barcode direct using Keyboard of your Phone.
You just put an input box and then you touch the box and when Keyboard appears, you will be able to scan barcode
I use it for work and that’s pretty useful to fill input box from barcode.
Hope it can help you.
