Abstract

Numerous embodiments of an apparatus and method of a smartcard having a dynamic display portion. In one embodiment, the smartcard includes a dynamic display portion made of an electronic ink, in which the dynamic display portion changes from a first display to a second display in response to an application use of the smartcard.

Claims

1. A smartcard, comprising:

a microprocessor to execute a plurality of applications;

a radio frequency identification tag;

a dynamic display portion to change a presented display image in response to receiving one of a plurality of display data sets;

a first display chooser to send a first of the plurality of display data sets to the display portion in response to the identification tag receiving a block of display information; and

a second display chooser, to send a second of the plurality of display data sets to the display portion in response to a command from one of the applications.

2. The smartcard of claim 1, wherein the first display chooser is a hardware component that does not require the microprocessor for operation.

3. The smartcard of claim 1, wherein the radio frequency identification tag further to exclusively provide power to the first display chooser.

4. The smartcard of claim 3, wherein the radio frequency identification tag further to exclusively provide power to the dynamic display portion to change the display image in response to the identification tag receiving the block of display information.

5. The smartcard of claim 1, wherein the second display chooser is another application executed by the microprocessor.

6. The smartcard of claim 1, further comprising a memory to store a portion of the plurality of display data sets.

7. The smartcard of claim 1, wherein the block of display information comprises the first display data set.

8. The smartcard of claim 1,

wherein the block of display information comprises an identifier string;

and

wherein the first display chooser further to choose as the first display data set, from the plurality of data sets, a set associated with the identifier string.

9. A method, comprising:

providing a smartcard having a microprocessor, a dynamic display portion, a radio frequency identification tag, a first display chooser and a second display chooser;

sending a first of a plurality of display data sets from the first display chooser to the dynamic display portion in response to the identification tag receiving a block of display information;

sending a second of a plurality of display data sets from the second display chooser to the dynamic display portion in response to the second display chooser receiving a command from an application executed by the microprocessor; and

changing an image presented by the dynamic display portion in response to the dynamic display portion receiving one of the plurality of display data sets.

10. The method of claim 9, further comprising powering the first display chooser exclusively with energy received by the identification tag.

11. The method of claim 10, further comprising powering the dynamic display portion, when changing the display image in response to the identification tag receiving the block of display information, exclusively with energy received by the identification tag.
