Yes. You can change anything and everything on the card at anytime. We have a very handy feature that allows you to re-configure the entire card's value, activation dates, expirations, and number of times it can be used. This feature is critical if you made a mistake, or have ordered cards to configure at a later date when your media is ready. This feature is conveniently located in your card gallery section directly under the card you have ordered. This is an excellent feature to create LIVE CONCERT CARDS!
