Abstract:
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.
Abstract:
A system of verifying registration information of a vehicle 500, 600 is provided. The system includes a license plate. The system further includes a radio frequency (RF) device, the radio frequency device including a radio frequency antenna and a chip, the RF device being embedded onto the license plate. The chip comprises a memory 505, the memory configured to store a security key and vehicle identification information, and a processor coupled with the memory, the processor configured to provide access to the memory based on a security key. The processor is further configured to receive a signal via the radio frequency antenna, the signal comprising a request to access the memory and a security key, compare the security key included in the received message with the security key stored in the memory, and receive an access request via the radio frequency antenna from an RF reader to read the vehicle identification information.
Abstract:
La presente invencion comprende un dispositivo de identificacion de radiofrecuencia que utiliza multiples frecuencias de operacion. En una modalidad de la presente invencion, una frecuencia (por ejemplo, una frecuencia ultra alta tal como 915 MHz, 800 MHz, 915 MHz o frecuencia de microondas tal como 2.45 GHz) se utiliza para la transmision de datos, y otra frecuencia mas (por ejemplo, una frecuencia baja o alta tal como 13.56 MHz) se utiliza para la penetracion de campo. En otra modalidad mas, se utiliza una frecuencia para leer la informacion recibida del dispositivo de identificacion de frecuencias multiples, y se utiliza otra frecuencia mas para escribir hacia el dispositivo de identificacion de frecuencias multiples. En una modalidad adicional, el dispositivo de identificacion de frecuencias multiples utiliza una antena para todas las frecuencias. En otra modalidad mas, el dispositivo de identificacion de frecuencias multiples utiliza dos o mas antenas para diferentes frecuencias, y una memoria comun. En otras modalidades, se pueden utilizar una o dos partes digitales, partes analogicas, antenas y memorias.
