There are no bar codes on the coupon, so unfortunately they can't be scanned at this time. Printing in black and white is perfectly acceptable. Having the physical coupon makes it easier for your server, and when we balance the next morning. They attach the coupon to your ticket and put in in their closeout bag at the end of their shift. I am looking into seeing if scanned coupons are something we can offer in the future. The system can scan the table tickets, so maybe there is an option for coupons. If so, we will add bar codes to future coupons and let everyone know. It would be a lot easier for us to just be able to scan a coupon and more convent for you.
