Decoding systems with a decoding engine running on a mobile device configured to be coupled and decoupled to a card reader with wake-up electronics

摘要

A decoding system has a decoding engine running on a mobile device. The decoding engine decodes signals produced from a read of a first party's financial transaction card, accepts and initializes incoming signals from a read of a first party's financial transaction card. A transaction engine runs on the mobile device and is coupled to the decoding engine. The transaction engine receives as its input decoded first party's financial transaction card information from the decoding engine, and serves as an intermediary between the first party and a second party, so that the first party does not have to share his/her financial transaction card information with the second party. The decoding system is configured to be coupled and decoupled to a card reader with wake-up electronics.
