It does get a different barcode each time a coupon is purchased.  I am just trying to avoid having to visually compare the one being redeem against a stack of void coupons.  So I was hoping there would be a barcode scanner for droid that can snap the picture and know if it's a duplicate.

But all the the coupon are the same there is no way if there is no barcode difference or serial number difference betwen every download of the coupon for the print out. that mean that every single coupon are the same so theoretically they are all duplicate of each other, so in make it impossible to make a difference betwen ea other

Sorry for the confusion.  The coupon does get a different barcode.  So when a customer buys a coupon it has an individual barcode for that coupon and they can then print from their printer.  I was concerned about people trying to make copies of duplicate coupons for redeeming and it would be difficult for me to visually look for duplicate barcode serial numbers during the redeeming process.
