The goal of this type of attack is to overpower the RF field so that communication with RFID tags in close proximity is rendered unusable. If an attacker uses enough power, she or he may be able to disable communications with all RFID tags in an entire warehouse.

This attack may have severe effects on RFID business applications. An example of this would be a signal jamming attack carried out against a large retail location. The retailer could be using RFID tags to track shipments and inventory and may also be storing pricing and other information on the tags. A successful attacker, using an RFID jamming device and an illegally overpowered antenna, who interfered with this process would make data collected by the RFID system unreliable, forcing the location to return to a pencil and paper system to confirm its inventory.
