System and method for a baseband nearfield magnetic stripe data transmitter

Abstract

A system for a baseband near field magnetic stripe data transmitter includes a mobile phone and a magnetic stripe transmission (MST) device. The mobile phone transmits a stream of pulses including magnetic stripe data of a payment card. The magnetic stripe transmission (MST) device includes a wave shaper, a driver and an induction device. The MST device receives the stream of pulses from the mobile phone, shapes and amplifies the received stream of pulses and generates and emits high energy magnetic pulses including the magnetic stripe data. The emitted high energy magnetic pulses are picked up remotely by a magnetic read head. The MST device shapes the stream of pulses to compensate for shielding, eddy current losses and limited inductance value of the magnetic read head.

Benefits of technology

[0007]In general, one aspect of the invention provides a system for a baseband near field magnetic stripe data transmitter including a mobile phone and a magnetic stripe transmission (MST) device. The mobile phone is configured to transmit a stream of pulses comprising magnetic stripe data of a payment card. The magnetic stripe transmission (MST) device includes a wave shaper, a driver and an induction device. The MST device is configured to receive the stream of pulses from the mobile phone, to shape and amplify the received stream of pulses and to generate and emit high energy magnetic pulses comprising the magnetic stripe data. The emitted high energy magnetic pulses are configured to be picked up remotely by a magnetic read head. The MST device shapes the received stream of pulses to compensate for shielding, eddy current losses and limited inductance value of the magnetic read head.

Problems solved by technology

The key impediment to adoption has been the lack of data transfer channel between mobile phones and the point of sale terminal.

Their wide scale adoption, however, is prevented by a lack of suitable reading devices at the point of sale, and in the case of NFC, also the lack of standardized NFC capability in many smart-phones.
