Abstract

A terminal for magnetic secure transmission (MST) includes a body including a magnetic head and a coil member wound around the magnetic head, and an electromagnetic wave shielding structure disposed around the magnetic head and being formed of a magnetic material.

Claims

1. A magnetic secure transmission (MST) terminal comprising:

a body comprising a magnetic head and a coil member wound around the magnetic head; and

an electromagnetic wave shielding structure disposed around the magnetic head and being formed of a magnetic material.

2. The MST terminal of claim 1, wherein the electromagnetic wave shielding structure is disposed outside of the body.

3. The MST terminal of claim 2, wherein the electromagnetic wave shielding structure is removably attached to the body.

4. The MST terminal of claim 3, wherein the electromagnetic wave shielding structure comprises a shielding portion and a support member configured to support the shielding portion and to be inserted around the body.

5. The terminal for MST terminal of claim 2, wherein the body comprises an in/out region of a magnetic card.

6. The MST of claim 5, wherein the electromagnetic wave shielding structure is disposed on the body and comprises the in/out region of the magnetic card.

7. The MST terminal of claim 6, wherein an angle formed by a portion of the electromagnetic wave shielding structure with a top surface of the body is adjustable.

8. The MST terminal of claim 6, wherein the electromagnetic wave shielding structure is divided into two regions by the in/out region, and

angles formed by each of the two regions and a top surface of the body are different.

9. The terminal for MST terminal of claim 1, wherein the electromagnetic wave shielding structure has a funnel shape.

10. The MST terminal of claim 1, wherein the electromagnetic wave shielding structure is disposed in the body.

11. The MST terminal of claim 10, wherein the electromagnetic wave shielding structure has a shape that is configured to surround the magnetic head.

12. The MST terminal of claim 10, wherein the electromagnetic wave shielding structure is configured to be inserted in a groove formed in the body.

13. An electromagnetic wave shielding structure for a magnetic secure transmission (MST) terminal, the electromagnetic wave shield comprising:

a shielding portion formed of a magnetic material; and

a support member configured to support the shielding portion and to be removably coupled to the MST terminal.

14. The electromagnetic wave shielding structure of claim 13, further comprising an in/out region of a magnetic card formed in the shielding portion.

15. The electromagnetic wave shielding structure of claim 14, wherein the shielding portion forms an angle with a top surface of the support member that is adjustable.

16. The electromagnetic wave shielding structure of claim 14, wherein the in/out region divides the shielding portion into two, and

angles formed by each of the two regions with the top surface of the support member are different.

17. The electromagnetic wave shielding structure of claim 13, wherein the shielding portion has a funnel shape.

18. The electromagnetic wave shielding structure of claim 13, wherein the shielding portion has a trapezoidal shape.
