Claim 14:
15. A computer-implemented method, comprising:
receiving, by a server system associated with a payment network, a payment transaction request and an audio signal comprising an ambient noise in surrounding of a merchant terminal of a merchant, wherein the ambient noise is recorded by the merchant terminal and comprises a plurality of sounds;
determining, by the server system, whether the merchant is an aggregated merchant or a non-aggregated merchant;
upon determining that the merchant is the aggregated merchant, processing, by the server system, the ambient noise for training a model of categorization of a type of the merchant; and
upon determining that the merchant is the non-aggregated merchant, performing processing, by the server system, the ambient noise included in the audio signal,
mapping, by the server system, the merchant to an industry from a plurality of industries available in the server system based at least on the model of categorization and processing of the ambient noise, and
storing, by the server system, the mapping of the industry and the non-aggregated merchant in a database associated with the server system,
wherein processing the ambient noise included in the audio signal comprises:
extracting one or more attributes for each sound of the plurality of sounds in the ambient noise;
combining each attribute of the one or more attributes with same attribute of the plurality of sounds in the ambient noise to create a variable associated with each attribute;
using the variable associated with each attribute to identify a prominent sound wave available in the ambient noise; and
determining the industry for the non-aggregated merchant based on the prominent sound wave using the model of categorization.
