Business management system

摘要

A point of sale system includes a point of sale terminal (201) that provides credit card information for a transaction to a communication port (203). The communication port (203) extracts a copy of the credit card information and the transaction information without interfering with the underlying communication and communicates the transaction and credit card information to a network, such as an Internet or public switched telephone network (PSTN) (102). The communication port (902) may emulate the network so that the point of sale terminal communicates as with the communication port as if it were communicating with a PSTN. The communication port (902) may convert the transaction and credit card information from one protocol into another protocol, such as an Internet protocol. The communication port (902) provides the extracted information via the network to a host processor for analysis. The analysis may include credit charge profile of users, individually or in the aggregate, and time of day distributions of charges.
