Ultrasonic near-field communication

An apparatus, comprising:

• one or more processors;
• and
• a computer-readable storage medium storing one or more computer program(s) which, when executed by the one or more processors, cause the one or more processors to perform a set of operations for near-field communication, the one or more computer programs comprising:
• instructions to detect, by a source device located at a point-of-sale, the proximity of a receiving device;
• instructions to encode purchase data on an audio signal with one or more ultrasonic frequencies;
• and
• instructions to transmit the encoded purchase data to the receiving device, wherein the encoded purchase data is transmitted using a speaker of the source device.

A computer-implemented method for near-field secure communication, comprising:

• detecting, by a source device located at a point-of-sale, the proximity of a receiving device;
• generating a key id for the source device, wherein the key id is stored on the source device;
• padding purchase data;
• encoding the purchase data with the key id on an audio signal with one or more ultrasonic frequencies;
• and
• transmitting the encoded purchase data to the receiving device, wherein the encoded purchase data is transmitted using a speaker of the source device.

A computer-implemented method for implementing a merchant loyalty program, comprising:

• detecting, by a source device located at a point-of-sale, the proximity of a receiving device;
• wherein the receiving device is associated with a specific customer;
• encoding qualifying purchase data on an audio signal with one or more ultrasonic frequencies;
• transmitting the encoded purchase data to the receiving device;
• and
• tracking the purchase data of the specific customer through a program stored on the receiving device or a server coupled to the source device.

A system for implementing a merchant loyalty program, comprising:

• one or more processors;
• and
• a computer-readable storage medium storing one or more computer program(s) which, when executed by the one or more processors, cause the one or more processors to perform a set of operations for implementing a merchant loyalty program, the one or more computer programs comprising:
• instructions to detect, by a source device located at a point-of-sale, the proximity of a receiving device;
• wherein the receiving device is associated with a specific customer;
• instructions to encode qualifying purchase data on an audio signal with one or more ultrasonic frequencies;

• and
• instructions to track the purchase data of the specific customer through a program stored on the receiving device or a server coupled to the source device.

A computer-implemented method for implementing a merchant loyalty program, comprising:

• providing a store value card to a source device, wherein the store value card is associated with a specific customer;
• detecting, by a receive device located at a point-of-sale, the proximity of the source device;
• receiving, from the source device, an audio signal with one or more ultrasonic frequencies, the audio signal encoded with the identity of the store value card;
• and
• deducting a purchase price from the store value card or charging the purchase price to a credit account or a bank account associated with the specific customer.

A system for implementing a merchant loyalty program, comprising:

• one or more processors;
• and
• a computer-readable storage medium storing one or more computer program(s) which, when executed by the one or more processors, cause the one or more processors to perform a set of operations for implementing a merchant loyalty program, the one or more computer programs comprising:
• instructions to provide a store value card to a source device, wherein the store value card is associated with a specific customer;
• instructions to detect, by a receive device located at a point-of-sale, the proximity of the source device;
• instructions to receive, from the source device, an audio signal with one or more ultrasonic frequencies, the audio signal encoded with the identity of the store value card;
• and
• instructions to deduct a purchase price from the store value card or charging the purchase price to a credit account or a bank account associated with the specific customer.

A computer-implemented method for providing a keyless lock, comprising:

• storing a key combination on a source device, wherein the key combination corresponds to a specific lock;
• detecting, by the source device, the proximity of the specific lock;
• and
• transmitting, from the source device, an audio signal with one or more ultrasonic frequencies, the audio signal encoded with the key combination;
• wherein the specific lock has a card reader, the car reader configured to decode the encoded key combination and unlock the specific lock if the key combination is valid.
