Loc_ID is a unique ID assigned to Merchants by Liquid Pay for identification of their Table No, Counter No, POS No etc depending on whether it is Pay@Table or Pay@Counter. This Loc_ID is related to Merchant Group ID, Merchant ID, Outlet ID, LocNo (aka Counter No, Table No, POS No etc). This way, a merchant or vendor can use a single unique ID to identify a table or a counter or a POS instead of having to use 4 IDs combined.
