Bar code scanning

I am about to tackle a new WinDev project which involves scanning Bar Codes. I have done this in the past but it was a very long time ago and it was not using WinDev. At that time most Bar Code Scanners were serial devices but I see that now many are USB or Bluetooth. A cursory look at the WinDev Help file seems to indicate that it supports serial devices but I would prefer cordless readers.
I have a meeting with the client next week and I would appreciate any input regarding things I should be aware of from someone who has done this in WinDev. I am using WinDev22.
Thanks,
Garry

Most, if not all, barcode scanners have TWO modes : serial and keyboard emulation.

- serial : even in USB or wireless, they come with a driver that make them seen as a serial device usable with the wlanguage sxxx fonctions
- keyboard emulation : everything scanned comes in as a keyboard entry, in the CURRENT FIELD

so in keyboard mode, you need to make sure that the correct field has the focus when scanning, or add a prefix to the scan so that it GETS the focus before the real data arrives

In serial mode, you can use events to detect a scan and act accordingly.

Both modes have their advantages, and of course the coding logic is quite different.
