Editing Frequent buyer card

The '''frequent buyer card''' (which may just remind someone of their [[account number]]) is a very commonly used system for rewarding the [[repeat customer]].

It is an almost ubiquitous thing, but takes several forms technologically:

*A [[card stock]] [[business card]] which is punched out by clerks with each purchase, typically of a [[meal]] [[drink]] or [[event admission]].  After a certain number of purchases/punches, typically ten, the "eleventh is free".  The card with ten punches on it is typically used as the [[coupon]].  There are also schemes which distribute stamps and let people paste them on cards that represent the rewards they want, a different number based on the value of the reward.

*A [[plastic stock]] [[credit card]]-like token that has raised type and an [[electronic stripe]] to make it easy to automatically process the card.  This is common with air '''frequent flyer''' programs.

*An [[RFID]] unit

*Etc.

Any of these might have a [[barcode]] on it.
