There are a few telltale signs that you can use to tell if a coupon has been photocopied. This is good for any of the cashiers, for people who trade coupons, for anyone who thinks photocopying coupons is okay to do, and also for anyone who wants to know how to tell the difference between a printed coupon and a photocopy.
There are 4 pictures below.
1) A picture of a coupon showing an item and the amount of the coupon. Also, note that the outside line is not cut out. There is a $ watermark on the coupon which also does not show up on photocopies.
2) A picture of the area around the coupon. This is NOT a cutting line. This is a security feature that should be cut around. Included in this line is a date and time stamp and security information. A photocopied coupon would show the exact same date and time on each coupon.
3) The bar code and UPC or PIN. While the bar code remains the same on each coupon. The UPC or PIN will be different on each coupon printed.
