It should be possible. There are several iPhone apps that offer that functionality. You should do a search for a similar BB product. **Update: I couldn't find anything for the BB after a brief search. Most of the iApps seem to generate a barcode from inputing a membership card number, and they claim to work best with handheld scanners with the screen at maximum brightness. I don't know about stores accepting a photo of a coupon though, they might want you to hand over the BB for remittance.
