support barcode scanning

[Cor-Jan]

For checking in wholesale products and for checking out we could use barcode scanners 1D bar/ean codes or 2D QR codes to scan and make sure that the identification of a product is done fast and without mistakes.

1D ean barcode scanners are cheap, but not able to scan QR and other 2D codes. A 2D scanner is much more expensive. Another option is to use a phone 2D barcodes scanning software like NEO reader.

• 1D scanner: many act as an external keyboard. Ways to implement this in the website:
  • give barcode field initial focus on relevant pages, skip to next after one is scanned
  • detect barcode entry within certain timeslot and handle entry
  • program barcode scanner to give key combination to focus next barcode field (if supported)
• 2D scanner:
• Mobile phone: need mobile version of foodsoft with scanning software integration.

When we'd support the popular Motorola LS2208 scanner (manual), that would probably cover most cases. It can be programmed to submit a sequence before and one after the scan, which could be a shortcut key that the web page detects.

This would be a nice jQuery plugin to catch barcode events: jquery-barcodelistener. And this to find event codes.
