Hello: Our school’s dormitory uses your company’s SO2E access controller, there are too many floors and room numbers, sometimes when students graduate or lose their cards, there are too many data to distinguish between that floor and that room number, the card is missing, the card with the room number on that floor has not been recovered, I heard that this product supports self-numbering card issuance and card deletion, I want to know how to set up some functions?

Hello: I am very grateful that you use our company's access controller product, in order to make it easier for you to operate this function, we provide you with the following video teaching, please watch the video:
