This is a metal airline ticket validation plate the size of a credit card. Airline ticket validation plates were used where a credit card would be placed in the old school manual credit card machines, using a four flight segment carbon copy airline ticket. Think of that old familiar sound “ca-chink” when making credit card purchases! It’s a great and unique collectible for airline enthusiasts.
