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.
