Read head device with selected output jack characteristics

摘要

A read head is configured to be coupled to the mobile device. The read head is positioned in a housing. The read head has a slot for swiping a magnetic stripe of a financial transaction card to enable a financial transaction between a buyer and seller. The read head reads data from the magnetic stripe and produces a signal indicative of data stored on the magnetic stripe. The read head includes an output jack adapted to be inserted at least one of the audio jack or microphone input port of the mobile appliance to provide a signal indicative of data stored on the magnetic stripe to, the mobile device. The output jack extends at least 2 mm from the housing.

主权项

1. A card reader system, comprising:
a housing having a slot for swiping a magnetic stripe of a financial transaction card to complete a financial transaction between a buyer and seller; a read head in the housing for reading data stored on the magnetic stripe and for producing a signal indicative of data stored on the magnetic stripe; an output jack adapted to be coupled to at least one of an audio jack or microphone input port of a mobile device for providing, to the mobile device, the signal indicative of data stored on the magnetic stripe; a card reader circuit with a control unit, the control unit being coupled to a pathway subsystem that is configured to direct bias voltage received from the mobile device to a card reader power subsystem, the card reader power subsystem including a modified charge pump and being configured to convert the bias voltage to a system voltage that is usable by the control unit, wherein the control unit configures the pathway subsystem to allow the card reader circuit to access the mobile device; and an encryption system in communication with a communication system and the control unit, wherein the control unit, in operation, provides for communication of encrypted information from the encryption system.
