There are many places online that offer plastic magnetic cards of high quality (Reward-It
as an example). Your main choices are quantity, double sided or single sided printing, and finally whether to have a magnetic strip on the back or use a barcode instead. We would always recommend using a magnetic strip to swipe a customer’s card or gift voucher. The customer number should be sequential, encoded on track 2 where possible. For gift cards, encode the voucher code on track 1as that supports text. HiCo encoding is greatly recommended to ensure the data is not wiped easily.
