Do I need a contract to upgrade my key card?

When the access card was renewed, the property owner said that he needed a contract ID card to renew it, and he could copy the contract to them. The property used the access card to brush it on the small processor, even if it was upgraded, it was also the upgrade of the control program.

The ic card for access control is actually a computer control system. Usually, upgrading is to improve and update the program of the control system. Before issuing access cards to end users, the available areas and user rights are determined by the system administrator. Users swipe their cards to enter the management area, and users without access cards or permissions are not allowed to enter the management area.
