Abstract: Systems and methods for performing token transactions are provided. In one embodiment, the invention provides for processing token transactions, including receiving an encrypted password for a debit card transaction, wherein the password was secured using encrypted debit-card information, decrypting the password using encrypted debit-card information for the debit card, recreating the password using actual debit-card information for the debit card, and forwarding the recreated password for subsequent transaction processing. The invention is suitable for implementation with other types of tokens in addition to debit-card tokens as well. The invention can be implemented in a scenario where the password includes a PIN block that is created by combining a clear or encrypted PIN for the token with token information.

Abstract: Implementations are provided for wirelessly transmitting and receiving data through sonic communication. A transmit device having a sonic transducer transmits a sonic carrier signal through the air with a digital representation of the data with a modulation protocol using sonic transmission frequencies in accordance with present invention. The sonic transducer operates to transmit the one or more sonic carrier signals carrying the modulated data over the air with sufficient gain to carry the signal to a receiver device where the data is demodulated using at least one sonic transducer of a receive device. The receive device may be configured to perform the demodulation of the data at one or more sonic transmission frequencies and in accordance with a sonic modulation protocol to provide a binary representation of the data. Ambient noise captured by the receiver device is processed along with the data transmitted over the sonic carrier signals.
