Hi NTMS,
If you deal with time limited services there are two approaches: first you save the entry time on the card and check it if the user want go out. In this case you have to write each time on card but your reader stations can be independent from a central server. But if you have a central server where every user is logged you do not need to write to the card because it is logged on the central server.
Your smartcard architecture is interlaced with your server and reader architecture.
