Coupon barcodes are useless to a customers

by on June 27, 2009

Q: I want to create a coupon list by scanning the barcodes of the coupons that are issued in each Sunday paper. What hardware and software do I need to do this?

A: The UPC code on the coupons doesn’t actually have any data stored inside of it. A UPC or barcode is just a pictorial representation of a number that can easily be read by a scanner. The computer then turns the UPC or barcode into a number that it can use to look up information. The number itself is much like a social security number in that it is a unique number.

You need to have the database that the number is associated with to get back useful information. Without the database you just have a number. We are not aware of a free database that stores coupon information.
