Coupon USB

i am suggesting the new type of usb product and system by grafting the usb and the couchers when you order pizzas or fried-chickens.
the original vouchers of delivery foods are supposed to be picked and then be kept for using, however, keeping those vouchers have risk of missing and those vouchers are mostly wasted.
considering such problems, i suggest usb vouchers and service systems for trying to maximize the usage of vouchers and decreasing the waste of vouchers.
