3 reasons why non-standard cards:
You have already offered different discounts and gifts to your customers. How else can you show them that you care about them?
Gift cards or loyalty cards you offer can elicit a new smile of your customers. Instead of cards of standard dimensions, try to offer them a card of non-standard shape. Let the cards be a new way to express the uniqueness of your brand and your attention to consumers.
The non-standard form of the card will give your company a competitive edge, and their practical side will extend the marketing campaign of your company. One unit can contain several small cards that can be used by all members of the family. Small cards can be pinned to keys as a pendant and remind users of your brand every day.
