Abstract
A method and device for transmitting product information using ultrasonic signals are disclosed. The device detects local availability of ultrasound-encoded product information while the device is at a location in proximity to an ultrasound transmitter. In response to detecting the local availability of the ultrasound-encoded product information, the device requests a user permission from a user of the device to capture the ultrasound-encoded product information. Upon obtaining the user permission to capture the ultrasound-encoded product information, the device receives, from the ultrasound transmitter, an ultrasonic signal encoded with a message containing respective information associated with a respective product. The device decodes the ultrasonic signal to obtain the message in a human-perceivable form.
