Abstract

Embodiments of the invention provide devices and systems for the transfer of information using multi-point contact on a capacitive surface. In one embodiment, the invention provides a device comprising: a first surface having a plurality of contact points arranged in a pattern and a second surface having a contact area electrically connected to the plurality of contact points, whereby the plurality of contact points on the first surface is activated by a user contacting the contact area on the second surface.

Claims

1. A credit card device comprising:

a first surface having a plurality of contact points arranged in a pattern; and

a second surface having a contact area electrically connected to each of the plurality of contact points,

whereby each of the plurality of contact points on the first surface is simultaneously activated by a user contacting and exerting a pressure against the contact area on the second surface and, when activated, the plurality of contact points is capable of transferring the pattern to a capacitive screen in contact with the first surface,

wherein the pattern is a pre-determined pattern representative of at least one of the following;

an account expiration date, a device expiration date, a credit card security number, or a name of an account holder.

2. The device of claim 1, wherein the plurality of contact points includes at least one positioning contact point.

3. The device of claim 1, wherein the pattern is a pre-determined pattern representative of an account number.

4. The device of claim 1, wherein the first surface is opposite the second surface and the plurality of contact points is opposite the contact area.

5. The device of claim 1, wherein:

the first surface includes an additional plurality of contact points arranged in an additional pattern; and

the second surface includes an additional contact area electrically connected to each of the additional plurality of contact points,

whereby each of the additional plurality of contact points on the first surface is simultaneously activated by the user contacting and exerting a pressure against the additional contact area on the second surface and, when activated, the additional plurality of contact points transfers the additional pattern to the capacitive screen.

6. A credit card system for transferring information, the system comprising:

a device having;

a first surface having a plurality of contact points arranged in a pattern; and

a second surface having a contact area electrically connected to each of the plurality of contact points; and

a capacitive screen with which the first surface of the device may be placed in contact,

whereby the pattern is transferred to the capacitive screen when each of the plurality of contact points on the first surface of the device is simultaneously activated by a user contacting the contact area on the second surface of the device,

wherein the pattern is a pre-determined pattern representative of at least one of the following;

an account number, an account expiration date, a device expiration date, a credit card security number, or a name of an account holder.

7. The system of claim 6, wherein the pattern is a pre-determined pattern representative of an account number.

8. The system of claim 7, further comprising:

a computer program product capable of translating the pre-determined pattern into the account number.

9. The system of claim 6, wherein the plurality of contact points includes at least one positioning contact point.

10. The system of claim 6, wherein:

the first surface of the device includes an additional plurality of contact points arranged in an additional pattern; and

the second surface of the device includes an additional contact area electrically connected to each of the additional plurality of contact points,

whereby each of the additional plurality of contact points on the first surface is simultaneously activated by the user contacting and exerting a pressure against the additional contact area on the second surface and, when activated, the additional plurality of contact points is capable of transferring the additional pattern to the capacitive screen in contact with the first surface.
