[Koha] Barcode Scanners

[Wascally Wabbit]

Is there a generally recommended bar code scanner to use for
check-in/check-out?

Would that same scanner work for doing inventory?

The scanner section of the documentation seems a bit sparse in describing
how to configure the scanner to work, perhaps I'm looking in the wrong
place?

And finally, is anyone using a mobile phone app to do barcode scanning?

Trying to get a general feel for what we should be looking for.

Thanks for any help!
