Deactivatable/reactivatable smart card recording apparatus

摘要

An automated system with one or more memory-card interface devices, a custom-formatted end-user memory card keeps track of the user's results, and a reactivation memory card controls the provider's recharging of the end-user memory card after the end-user memory card expires. The contents of the reactivation memory card are updated in order to track its use by the provider of the readings.
