The method may comprise capturing at least one further image or at least one further video of the same individual(s) after x time; and performing verification of occupants of the vehicle based on the captured at least one image or at least one video, and at least one further image or at least one further video. ## Claims ### Claim 1 A method to change an identification code of a radio frequency identification (RFID) transponder, the method comprising: capturing at least one image or at least one video of individual(s); and changing an identification code of the RFID transponder to correspond to a number of the individual(s); wherein the RFID transponder is a multi-frequency RFID transponder which comprises: a multi-frequency chip containing the identification code; a first antenna, operated at a first frequency band, connected to the multi-frequency chip; and a second antenna, operated at a second frequency band different from the first frequency band, connected to the multi-frequency chip; wherein the first antenna, the second antenna and the multi-frequency chip are configured and arranged such that the RFID transponder is readable by an RFID reader at the first frequency band to obtain the identification code; and the RFID transponder is controllable by a terminal different from the RFID reader at the second frequency band to change the identification code. ### Claim 2 (depends on 1) The method of claim 1, wherein the RFID transponder is a passive switchable, selectable or changeable transponder attached to a vehicle. ### Claim 3 (depends on 1) The method of claim 1, further comprises: x time after the step of capturing at least one image or at least one video of individual(s), capturing at least one further image or at least one further video of the individual(s); and verifying the changed identification code with the captured at least one further image or at least one further video of the individual(s). ### Claim 4 (depends on 3) The method of claim 3, wherein the x time is predetermined, random, or triggered by at least one event. ### Claim 5 (depends on 3) The method of claim 3, wherein the step of verifying the changed identification code comprises one or both of the following: determining if the number of the individual(s) before and after x time are the same; and determining if each of the individual(s) is the same person before and after the x time. ### Claim 6 (depends on 1) The method of claim 1, wherein the step of changing the identification code of the RFID transponder is based on at least one image processing technique of the captured at least one image or at least one video to determine the number of the individual(s) in the captured at least one image or at least one video. ### Claim 7 (depends on 1) The method of claim 1, wherein the step of changing the identification code of the RFID transponder is performed manually by one of the individual(s) in a vehicle; and the step of capturing at least one image or at least one video of individual(s) in the vehicle is to verify that the step of changing the identification code of the RFID transponder is performed correctly; and wherein the at least one image or at least one video is (are) deleted thereafter. ### Claim 8 (depends on 1) The method of claim 1, wherein the at least one image or at least one video is captured by the terminal that controls the RFID transponder to change the identification code. ### Claim 9 (depends on 1) The method of claim 1, wherein the at least one image or at least one video is captured by a different terminal different from the RFID reader and different from the terminal that controls the RFID transponder to change the identification code. ### Claim 10 (depends on 1) The method of claim 1, wherein the at least one image or at least one video of the individual(s) is captured by a handheld device with at least one camera. ### Claim 11 (depends on 3) The method of claim 3, wherein the step of verifying the changed identification code with the captured further image or further video is performed locally by a handheld device with at least one camera; and wherein the handheld device stores a pass-fail verification confirmation locally or sends a pass-fail verification confirmation to a server after the step of verifying is completed. ### Claim 12 (depends on 11) The method in claim 11, wherein the at least one image or the at least one video and the at least one further image or the at least one further video is (are) deleted after the step of verifying is completed. ### Claim 13 (depends on 1) The method of claim 1, wherein the identification code is a unique code made up of EPC memory, or user memory of the multi-frequency chip, or both. ### Claim 14 (depends on 1) The method of claim 1, wherein the first frequency band is a UHF band and the second frequency band is an HF band. ### Claim 15 (depends on 1) The method of claim 1, wherein the first antenna is a UHF dipole-type antenna and the second antenna is an HF or NFC coil. ### Claim 16 (depends on 1) The method of claim 1, wherein the identification code of the RFID transponder is changed according to the number of individual(s) in a vehicle for entering High Occupancy Vehicle (HOV) or High Occupancy Toll (HOT) express lanes. ### Claim 17 (depends on 11) The method of claim 11, wherein passing the step of verifying cumulates points for an account associated to a vehicle for fulfilling at least one riding condition. ### Claim 18 (depends on 17) The method of claim 17, wherein the riding condition comprises the usage of High Occupancy Vehicle (HOV) or High Occupancy Toll (HOT) express lanes. ### Claim 19 A system for High Occupancy Vehicle (HOV) or High Occupancy Toll (HOT) applications, comprising: a radio frequency identification (RFID) transponder attached to a vehicle; a mobile terminal configured to: change an identification code of the radio frequency identification (RFID) transponder to correspond to a number of individual(s) in the vehicle; and capture at least one image or at least one video of the individual(s) in the vehicle before x time; capture at least one further image or at least one further video of the individual(s) in the vehicle after x time; and verify the changed identification code with the captured image or video, and the captured further image or further video; wherein the RFID transponder is a multi-frequency RFID transponder which comprises: a multi-frequency chip containing the identification code; a first antenna, operated at a first frequency band, connected to the multi-frequency chip; and a second antenna, operated at a second frequency band different from the first frequency band, connected to the multi-frequency chip; wherein the first antenna, the second antenna and the multi-frequency chip are configured and arranged such that the RFID transponder is readable by an RFID reader at the first frequency band to obtain the identification code; and the RFID transponder is controllable by a terminal different from the RFID reader at the second frequency band to change the identification code.
