Abstract
Example embodiments of systems and methods for contactless card verification include a contactless card including a substrate, a processor, and a memory, wherein the memory contains a first applet and a second applet, and a recipient device in data communication with the contactless card, wherein the second applet is configured to retrieve one or more parameters from the first applet via an interface; and wherein the second applet is configured to transmit the one or more parameters to the recipient device for verification.
Claims20
A contactless card, comprising:
- a processor;
- and
- a memory containing a first applet and a second applet,
- wherein:
- the first applet is configured to access a counter,
- the processor is configured to update the counter based on a failed read attempt of the contactless card,
- the second applet is configured to retrieve data from the first applet,
- the first applet is precluded from communication external to the contactless card by the second applet, and
- the second applet is configured not to transmit data from the first applet for verification when the counter exceeds a threshold number.
A method performed by a contactless card comprising a processor and a memory containing a first applet and a second applet, the method comprising:
- updating, by the processor, a counter based on a failed read attempt of the contactless card;
- retrieving, by the second applet, data from the first applet;
- precluding, by the second applet, the first applet from communication external to the contactless card;
- and
- when the counter exceeds a threshold number, not transmitting, by the second applet, data from the first applet for verification.
A non-transitory computer-readable medium containing instructions for execution by a contactless card comprising a processor and an memory, wherein, upon execution of the instructions, the instructions perform procedures comprising:
- updating, by the processor, a counter based on a failed read attempt of the contactless card;
- retrieving, by the second applet, data from the first applet;
- precluding, by the second applet, the first applet from communication external to the contactless card;
- and
- when the counter exceeds a threshold number, not transmitting, by the second applet, data from the first applet for verification.
