Abstract:
1. A method of disambiguating ambiguous merchant identification data received from an acquirer as part of an authorization request for a cashless transaction, the method comprising: storing in a binary-searchable non-transitory computer-readable medium a first set of unambiguous merchant identification data having plural data entries therein, each entry corresponding to a merchant; performing a binary search of the first set of unambiguous merchant identification data using search keys based upon the ambiguous merchant identification data to determine whether one or more entries of the first set satisfies at least one of a hierarchical second set of partial match criteria for comparing the ambiguous merchant identification data with the first set of unambiguous merchant identification data; and assigning an entry of the first set of unambiguous merchant identification data to correspond with the ambiguous merchant identification data where at least a predetermined number of the second set of partial match criteria are met.
