Abstract
In certain embodiments, token data may be generated, updated, and presented on a token display of a token. In some embodiments, a communication session may be initiated between a token and a terminal. Authentication data stored on the token may be replaced with updated authentication data. Updated token data may be generated based on updated authentication data. The token data on an electrophoretic display may be replaced with the updated token data.
Claims20
A hardware security module (HSM) card configured with a post-session triggering mechanism to generate and replace data displayed and stored on the HSM card after a communication session with a card processing terminal even when the card processing terminal is no longer powering the HSM card, the HSM card comprising:
- an HSM configured to store a private key and generate authentication data based on the private key;
- a capacitor configured to receive power wirelessly from a terminal, store power, and provide power to components of the HSM card;
- an electrophoretic display configured to present card data;
- and
- circuitry configured to perform operations comprising:
- initiating, while the electrophoretic display is not powered by the capacitor and is displaying the card data, the communication session between the HSM card and the terminal during which the authentication data is transmitted to the terminal;
- in response to completion of the communication session with the terminal, transmitting, to the HSM, a refresh signal indicating refreshing the authentication data to cause the HSM to generate and replace the authentication data with updated authentication data, wherein the updated authentication data is generated by the HSM based on the private key;
- in response to obtaining the updated authentication data from the HSM in connection with the refresh signal, generating updated card data based on the updated authentication data;
- replacing the card data on the electrophoretic display with the updated card data by causing the capacitor to power the electrophoretic display and updating the electrophoretic display to present the updated card data while (i) the electrophoretic display is powered by the capacitor and (ii) the capacitor is no longer being powered by the terminal;
- and
- in response to completion of updating the electrophoretic display, causing the capacitor to stop powering the electrophoretic display, thereby maintaining presentation of the updated card data on the electrophoretic display and reserving power in the capacitor.
A token comprising:
- a capacitor configured to receive power from a terminal, store power, and provide power to components of the token;
- an electrophoretic display configured to present token data;
- and
- circuitry configured to perform operations comprising:
- initiating a communication session between the token and the terminal during which authentication data stored on the token is transmitted to the terminal, the token presenting token data on the electrophoretic display;
- after completion of the communication session with the terminal, causing replacement of the authentication data stored on the token with updated authentication data;
- generating updated token data based on the updated authentication data;
- and
- replacing the token data on the electrophoretic display with the updated token data by updating the electrophoretic display to present the updated token data while the electrophoretic display is powered by the capacitor.
A non-transitory, computer-readable medium storing instructions that, when executed by one or more processors, cause operations comprising:
- initiating a communication session between a token and a terminal during which authentication data stored on the token is transmitted to the terminal, the token presenting token data on a token display;
- after completion of the communication session with the terminal, causing replacement of the authentication data stored on the token with updated authentication data;
- generating updated token data based on the updated authentication data;
- and
- replacing the token data on the token display with the updated token data by updating the token display to present the updated token data while the token display is powered by an energy storage device.
