Since iForm Builder no longer supports idBlue, I was looking for an RFID solution for my check-out module. I found SERIALio's idChamp RS3 as a great replacement. It supports SPP and HID profiles. With the RS3, I am able to read the tag and input the tag ID using a TEXT widget. Then I linked the text widget to a database look-up function, and now my check-out module gives me the SKU and the DESCRIPTION of the item that was just scanned.
