Claim 7:
8. A server system in a payment network, the server system comprising:
a communication interface configured to receive a payment transaction request and an audio signal comprising an ambient noise in surrounding of a merchant terminal of a merchant, the ambient noise comprising a plurality of sounds;
a memory comprising executable instructions; and
a processor communicably coupled to the communication interface and configured to execute the executable instructions to cause the server system to at least:
determine whether the merchant is an aggregated merchant or a non-aggregated merchant;
upon determining that the merchant is the non-aggregated merchant, process the ambient noise to determine a type of the merchant;
map the merchant to an industry from a plurality of industries available in the server system based on the type of the merchant; and
store the mapping of the industry and the merchant in a database associated with the server system,

wherein upon determining that the merchant is the aggregated merchant, the server system is caused to:
extract one or more attributes for each sound of the plurality of sounds in the ambient noise;
combine 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;
use the variable associated with each attribute to identify a prominent sound wave available in the ambient noise;
combine each attribute of the one or more attributes of each sound to form a sound wave corresponding to each sound;
determine phase angle of the prominent sound wave and the sound wave associated with each sound;
use the phase angle of the prominent sound wave and the sound wave associated with each sound to determine the type of the merchant;
map the merchant to the industry based on the type of the merchant using the phase angle of the prominent sound wave and the sound wave associated with each sound; and
store a merchant-industry mapping for the aggregated merchant in the database.
