US Patent:

20180060858, Mar 1, 2018

Filed:

Nov 2, 2017

Appl. No.:

15/802416

Inventors:

- Burlington MA, US
Zhujie (Luke) Liu - Lexington MA, US

Assignee:

Samsung Pay, Inc. - Burlington MA

International Classification:

G06Q 20/34
G06Q 20/20
G07F 7/08
G06K 7/08

Abstract:

A contactless payment device and method streams a sequence of magnetic-field pulses directly to two magnetic-stripe read heads of a point-of-sale terminal. The stream of pulses includes essential information needed to approve a transaction. The essential information is structured for a primary “channel” associated with one of the read heads. A series of “proxy” bits are included in the stream in order to satisfy the data collection requirements for a secondary channel associated with the other read head. The proxy bits are included in a custom bit stream that may be used to improve acceptance of payment transmission data at a POS terminal.
