Developers must supply the required parameters to cancel multi-room cards. To use the contactless card issuance, reading, and cancellation APIs, users must download the QR Master application. Administrators must enable issuance and printing permissions for the member in Member Management.

If you need to use induction card issuance, card reading and other functions, please first connect creatorMobile/creatorEmail to the mobile phone or email field in the lock shopkeeper-management-member management. At the same time as the interface is docked, you need to go to the member management To enable members to issue printing permissions, the specific operations are as follows: Login lock shopkeeper-management-member management-select room permissions-after you choose, to issue printing permissions / sharing passwords

Canceling a multi-room card cancels access to all rooms on the card by default. Call readCard again after cancellation to get the latest card status.
