You cannot set the expiry date for the cards in the device. You need to write a scheduler to run in every midnight. The scheduler should remove the card information of the user or remove the user from the device once the subscription to the user is expired.

This is the only way you can achieve your requirement.

You don't.
You store the expiry date on the system that the card reader connects to, and each time he swipes you log the activity and check the card validity. This isn't a reader function- it's down to your database to hold all details. For example, if a member signs up and pays his subscription - but then the payment "bounces": the card reader has no way to know that the member hasn't paid and should reject the card and alert the staff.

All you store on the card is a card ID - the reader reads it and transfers that to a central system which looks up the member details and instructs the door to open or not. Nobody stores that locally on the card!
