Can I change my card design after processing the cards?

Yes.

You may make as many changes to card templates as you like, now or in the future. In fact, your plan includes free card templates (up to 3 on Small Business, up to 10 on Growth, UNLIMITED on Enterprise), and each template beyond that is $50.00. Many clients use multiple designs, such as for staff and students, or for temporary and permanent employees. If you update the templates, for example with a new expiration date, you will not need to change your personnel data.
