Method of compiling city guide database using payment system data

摘要

A method includes receiving transaction data from a payment network. The transaction data may represent payment account transactions. A subset of the transaction data may be associated with a district in an urban area. A summary characteristic of the district may be generated on the basis of the subset of transaction data associated with the district. The district may be represented by a color or a shade on a map. The map may be transmitted to a user's mobile device.
