Embodiment Construction

[0036] Various non-limiting embodiments will be described more fully hereinafter with reference to the accompanying drawings, in which some example embodiments are shown.

[0037] Figure 1A to Figure 1C is a block diagram illustrating a payment system including a magnetic secure transmission (MST) device according to some example embodiments.

[0038] refer to Figure 1A , in some example embodiments, the payment system (or electronic system) 10 includes a mobile device 100 , an MST device 200 , a POS terminal 400 and a transaction processor 450 . The mobile device 100 and the MST device 200 may be referred to as electronic devices. The MST device 200 may be coupled to the mobile device 100 through an input / output (I / O) interface 109 of the mobile device 100 . The I / O interface 109 may include, but is not limited to, an audio jack or an earphone jack of a mobile device. The MST device 200 may be provided in the form of a dongle or capsule coupled to the I / O interface 109 ....

Abstract

A magnetic secure transmission (MST) system includes a switching circuit, an inductor, and a control circuit. The control circuit is configured to control the switching circuit to adjust a level of current in the inductor. The inductor current may be adjusted by a first amount over a data transmission period such that the inductor emits a magnetic pulse including a first magnitude. The inductor current may be kept constant during a first sub-period of a data non-transmission period and may be changed by a second amount at a constant slope during a second sub-period of the data non-transmissionperiod, such that the inductor emits a magnetic pulse including a second magnitude during the second sub-period of the data non-transmission period. The second amount is less than the first amount. The first magnitude is greater than a threshold value. The second magnitude is less than the threshold value.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2016-0097850 filed with the Korean Intellectual Property Office on August 1, 2016 and U.S. Patent Application No. 15 / 426397 filed with the United States Patent and Trademark Office on February 7, 2017 rights and interests, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to contactless payment, in particular to a magnetic secure transmission device, a payment system including the magnetic secure transmission device, and / or an operating method thereof. Background technique [0004] The transmission of magnetic stripe data is mainly carried out by scanning the magnetic stripe card over the entry reader (MSR) to realize payment, identification (ID) and access control functions. Mobile wallet applications on smartphones and tablets have difficulty interfacing with existing point-of...
