An account is managed using information read from a dual frequency transponder. Information stored on the dual frequency transponder can be read by a NFC-enabled device and by a UHF RFID reader. The information links, corresponds, or otherwise provides access to account information stored at a remote server. For example, a NFC-enabled device can read the information from the dual frequency transponder and use that information to enable instant and on-the-spot recharging of a toll account. In addition, a UHF RFID toll reader can scan information from the dual frequency transponder and use that information to debit toll charges from the correct toll account. The dual frequency transponder can be embedded in a license plate and read using a reader placed in the road. Additionally, the transponder can be configured to function at the correct frequency only when a valid vehicle registration sticker is applied to the license plate.

An RFID tag includes a booster antenna, a feeding loop, an RFID module, and a sheet-like insulating base. The insulating base includes first and second sides that are opposite to each other. The booster antenna is comprised by one metal wire having one end on the first side of the insulating base and the other end on the second side of the insulating base and includes a first curved portion that reverses a direction of the metal wire extending from the one end and a second curved portion that reverses a direction of the metal wire, which is reversed by the first curved portion, to connect to the other end. Moreover, the RFID module is disposed in a region surrounded by the metal wire including the first curved portion and the second curved portion.

An antenna pattern used in a UHF frequency band RFID inlay is provided with a substance; a dipole antenna formed from a metal foil upon the front surface of the substance; and a sub-element formed from a metal foil upon the back surface of the substance, wherein the dipole antenna is provided with a loop portion having a IC chip connecting portion; a pair of meanders configured to respectively extend from the loop portion so as to be line symmetrical; and capacitance hats, the sub-element has a pair of U-shapes, and a part of the sub-element overlaps with the dipole antenna through the substance.

The present disclosure is generally directed to an RFID tag for use with a metal fastener where the fastener operates as the antenna of the RFID tag. The RFID tag includes a microchip for storing data. The chip is electrically coupled to the metal fastener in order to receive and transmit the RF signal, the metal fastener thereby operating as the antenna for the RFID tag.

Example embodiments of systems, methods, and computer-accessible mediums for transaction authorization are provided. An exemplary system can comprise a card including an input device and a display device in data communication with a server. The server can generate an authorization passcode upon an initiation of a transaction session, and the card can receive an entered passcode through the input device, display the entered passcode on the display device, and transmit the entered passcode to the server for comparison to the authorization passcode. Upon a determination that the entered passcode is a match for the authorization passcode, the server can transmit a match notification indicating the transaction session is valid, and upon a determination that the entered passcode is a mismatch for the authorization passcode, the server can transmit a mismatch notification terminating the transaction session.

A method and apparatus for identifying a location of a radio-frequency identification tag. A hand-held locator device is configured to transmit a first signal and a second signal. A frequency of the first signal changes through a first range of frequencies and is transmitted in a range of directions corresponding to the first range of frequencies. A frequency of the second signal changes through a second range of frequencies and is transmitted in the range of directions corresponding to the second range of frequencies. A difference frequency signal, having a frequency that is a difference between the frequency of the first signal and the frequency of the second signal, is received from the radio-frequency identification tag. The difference frequency signal is processed to determine and display a direction of the radio-frequency identification tag from the locator device.
