Abstract
Embodiments are directed to methods and techniques for providing power via piezoelectric components on contactless cards.
Claims18
A contactless card, comprising:
- one or more interfaces comprising contact pads and a chip, a magnetic stripe, a near-field communication (NFC) interface and antenna, or a combination thereof, the one or more interfaces to enable performance of transactions;
- a piezoelectric component configured to detect physical stress or force applied thereto, and in response to the physical stress or force, generate electrical power;
- a button located on a first side of the contactless card, the button slidably engageable with a track to slide the button between a first position and a second position, wherein, in the first position, the button is disengaged with the piezoelectric component, and wherein a physical stress or force is applied to the button to cause the button to slide into the second position, and in the second position, the button is caused to physically engage the piezoelectric component to thereby generate the electrical power, wherein the piezoelectric component includes a seismic mass attached to crystal elements to detect an acceleration applied to the button, the electric power generated by piezoelectric component being further based on the detected acceleration;
- and
- a display device coupled with the piezoelectric component via a transmission line, the display device to receive the electrical power from the piezoelectric component via the transmission line and to display information in response to receiving the electrical power.

A method to power a contactless card, the contactless card including one or more interfaces comprising contact pads and a chip, a magnetic stripe, a near-field communication (NFC) interface and antenna, or a combination thereof, the one or more interfaces to enable performance of transactions, and a display device with a piezoelectric component, the method comprising:
- receiving a physical stress or force by a button implemented on the contactless card, thereby causing the button to slide along a track from a first position, wherein the button is disengaged with the piezoelectric component, to a second position, whereby the button is caused to physically engage the piezoelectric component;
- generating, by the piezoelectric component, electrical power in response to the button physically engaging the piezoelectric component as a result of the physical stress or force, wherein the piezoelectric component generates the electric power by using a seismic mass attached to crystal elements to detect an acceleration applied to the button;
- providing, by the piezoelectric component, the electrical power to the display device, wherein the piezoelectric component and the display device are coupled via an interconnect embedded in the contactless card;
- and
- displaying, by the display device, information in response to receiving electrical power from the piezoelectric component.
