The customer's logo and design is reproduced on a plastic card and a unique number is added to each individual card. The vast majority of these are constructed using PVC (polyvinyl chloride) plastic. Once printed with the customer's design, the card must be "finished" to protect the printed design, then numbered to allow for card activation.
There are two basic types of finish applied to gift cards: UV coating or lamination.
Card numbering—the last step in production—can be in the form of bar codes, magnetic stripe encoding, human readable numbers, or any combination of these. In the numbering step, it is critical to ensure that no duplicate numbers are produced and that the method used to apply the numbers (thermal transfer, inkjet, etc.) produces a number that will be readable for the life of the card.
