The original elevator card belonged to the sixth floor, but now I want to upgrade to the twentieth floor, is that ok?

You must have the corresponding software and hardware support to read and write the data in the elevator card. Access card upgrades can only be made at the place where the access card was originally processed. Because this is an upgrade of the control program.

Access control using ic card is actually a computer control system. Normal upgrade is usually to improve and update the program of the control system, and this upgrade is also normal and necessary. Usually, the upgrade of the control program does not necessarily need to re-authorize (swipe) the IC card.

After the upgrade, you should be able to use the original access card, because the serial number is the same.

But if you can't or are not sensitive, you can go to the property to upgrade the access card.
