I have no idea whether this will be a generic coupon or e-mail specific... But the posted coupon image clearly has a barcode in the lower right corner..
The barcode is the exact same for all survey respondents. It is not generated individually... I know because I filled out two e-mail surveys and the $5 coupon was identical on both. It is a .JPEG file stored on a server.
Also, as a Smashburger veteran... I know that they don't even have barcode scanners at the restaurant, only a fouchscreen POS register. The only number of significance on that coupon is the small one that says "PLU 6509". That is the Offer Code that they look for on the promo screen which takes off the discount on your order.
