METHOD AND SYSTEM FOR INFORMATION EXCHANGE BETWEEN DEVICES Russian patent published in 2022 - IPC H04W12/50 G10L25/00 G06Q20/40 G06F21/44 

FIELD: computer technology.

SUBSTANCE: technical solution generally relates to computing and, more specifically, to systems and methods for implementing the exchange of information between two or more mobile computing devices and/or other computing systems. This communication method allows two or more devices to pinpoint each other's location using the built-in microphone to analyze small samples of the surrounding sound space and generate a hash. These hashes are sent back to the cloud database where they are compared and matched against other hashes, and if there is a match, the devices can immediately exchange whatever information they wish. The hash can be done both on the device and on the server. Numerous open source and commercial perceptual hashing algorithms can be used to sample and match audio hashes.

EFFECT: technical result is an increase in the efficiency of the rapid exchange of financial information between mobile devices, terminals and other gadgets.
