This is an original promotional method.
The key tag card is the most widespread way of maintaining customer loyalty used by marketing banners. This promotional tool has a double advantage:
First, cardholders are generally entitled to a discount or a bonus on their purchases, which encourages them to increase their number of visits to the affiliate merchant.
In addition, its practical size that can be attached to a key ring has the advantage of being seen regularly and close at hand.
Generally, an individual bar code printed on the back of the key tag card is used to identify the client.
The triple key tag card model is offered.
