Abstract
The present invention provides self-disabling tamper evident gift cards, and methods for making and using the gift cards. The gift cards comprise a hidden lower level activation code, and an upper level activation code that is visible. The gift cards incorporate one or more features that render either the lower level or upper level, or both, activation codes unreadable once the lower level activation code is revealed. This prevents card activation at a later time after a first instance when the activation code is accessed.
