Abstract
During admission to a location, a machine reader optically reads original machine-readable data on an original admission ticket and stores an original code based on the original machine-readable data and original user-specific information in re-writeable electronic memory on the original admission ticket while the original user is entering the location. The original user is then provided initial entry to the location. After the initial entry, a potential admission ticket is received at the location from a potential user. The machine reader optically reads potential machine-readable data on the potential admission ticket at the location, and the machine reader compares a potential code based on the potential machine-readable data and potential user-specific information to the original code stored in the re-writeable electronic memory on the original admission ticket. The potential user is provided re-entry to the location only if the potential code matches the original code.
