VENDING APPROVAL SYSTEMS, METHODS, AND APPARATUS USING CARD READERS

摘要

Methods, systems, and apparatus for obtaining application data using a card reader having a pass-through mode and an automatic polling mode are disclosed. Application data may be obtained by enabling the pass-through mode of the card reader, instructing the card reader to poll for an exchange event, identifying the exchange event, identifying a subject of the exchange event, and obtaining application data from the subject when the subject of the exchange event is a predefined application. The pass-through mode may be disabled and the automatic polling mode may be enabled after the application data is obtained. An account number from the subject of the exchange event may also be obtained for use in authorizing a vending transaction.
