摘要：
A method, system and apparatus for encrypting a consumer identification number contained in a portable consumer device by gradually changing a consumer identification number when an observable moment is observed is disclosed. Observable moments can be exposure to light or an electromagnetic field, use of the portable consumer device or a change in temperature. A pattern or history of how the consumer identification number is gradually changed is used to authenticate the portable consumer device or the consumer.
