An Apple ID application would have saved me forty bucks

My discount coin idea is a killer app.

Currently Hobby Town sends me a paper bearer asset, a 20% of at the local store.  I get that discount from on line purchases. The discount coupon is 4 by 8 inches, heavy paper, and I am not used to carrying them around. So, twice, I went up to Hobby Town and forgot my discount coupon.

The discount coin app works fine under Apple ID, if I could have had a smart contract manage my discount coupons as discount coins, then I would have saved the forty bucks. My Smart iPod would have had the discounts in its possession, an delivered them digitally on checkout.
