Abstract
A predetermined ID code is set in a server, and a radio frequency identification (RFID) tag is configured on an electronic device. A tag ID code of the RFID tag is received by a reader and then is transmitted to the server. The server is used to compare the tag ID code and the predetermined ID code. When the tag ID code is the same as the predetermined ID code, the server is arranged to transmit an enable signal to grant the access of the electronic device. When the tag ID code is different from the predetermined ID code, the server is arranged to send a disable signal to deny the access of the electronic device.
Claims14
A radio frequency identification (RFID) security method, comprising the steps of:
- a. a reader receiving a tag ID code of an RFID tag, and transmitting the tag ID code to a server, wherein the RFID tag is configured on an electronic device, and the server stores a predetermined ID code;
- b. the server determining whether the tag ID code is the same as the predetermined ID code;
- b1. when the tag ID code is the same as the predetermined ID code, the server transmitting an enable signal to the RFID tag to grant an access of the electronic device through a controller of the electronic device;
- and
- b2. when the tag ID code is different from the predetermined ID code, the server transmitting a disable signal to the RFID tag to deny the access of the electronic device through the controller of the electronic device.
A radio frequency identification (RFID) security system, comprising:
- an electronic device having an RFID tag, wherein the RFID tag corresponds to a tag ID code;
- a reader arranged to receive the tag ID code;
- and
- a server electrically connected to the reader and having a predetermined ID code, the server arranged to receive the tag ID code from the reader and determine whether the tag ID code is the same as the predetermined ID code, wherein when the tag ID code is the same as the predetermined ID code, the server is arranged to transmit an enable signal to the electronic device to grant an access of the electronic device through a controller of the electronic device, and when the tag ID code is different from the predetermined ID code, the server is arranged to transmit a disable signal to the electronic device to deny the access of the electronic device through the controller of the electronic device.
A radio frequency identification (RFID) security method, comprising the steps of:
- a. transmitting a trigger signal to an RFID tag by a reader to enable a timer of an electronic device to count a duration of time, wherein the RFID tag is configured in the electronic device;
- and
- b. a controller of the electronic device denying an access of the electronic device when the duration of time exceeds a predetermined time duration.
