If a car is stolen, can its RFID tag be deactivated so that readers will not allow the vehicle to enter premises—that is, so that a gate will not open?

Jeffrey,

The way most RFID systems work is that a reader interrogates a tag, and its ID number and other data are forwarded to a back-end system. That system determines what to do when the tag is read, such as opening a gate or charging someone’s account for using a bridge or tunnel, in the case of toll collection. As such, there’s no need to deactivate the tag.

All you would need to do is remove entrance permission in the back-end system for the tag ID of the stolen vehicle. If the car were to try to enter the lot, its tag would be read and the ID would be sent to the back-end system, which would determine that access should not be granted to that car. As such, it would not lift the entry gate.
