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 communication system, comprising:
- a contactless card including a processor and a memory, the memory containing a first applet and a second applet, wherein:
- the first applet is configured to access one or more parameters, wherein the one or more parameters include a counter,
- the contactless card is configured to update the counter based on one or more failed read attempts of the contactless card, and
- the first applet is precluded from data communication external to the contactless card by the second applet;
- and
- an application comprising instructions for execution on a device, the application in data communication with the contactless card via the second applet,
- 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 application.
A method of communicating with a contactless card, comprising:
- establishing communication via an interface between a first applet and a second applet contained in a memory of a contactless card;
- retrieving, by the second applet, verification data from the first applet via the interface,
- wherein the verification data includes a counter, and
- wherein the counter is updated based on one or more failed read attempts of the contactless card;
- retrieving, by the second applet, offline verification data associated with a user of the contactless card from one or more additional applets;
- establishing communication between the second applet and an application;
- transmitting, via one or more shareable objects, the verification data from the second applet to the application;
- and
- authenticating the verification data by the application.
A contactless card, comprising:
- a processor;
- a memory containing a first applet and a second applet, wherein the data is accessible to the first applet;
- and
- an interface wherein:
- the first applet is configured to access one or more parameters, wherein the one or more parameters include a counter,
- the contactless card is configured to update the counter based on one or more failed read attempts of the contactless card,
- the second applet is configured to retrieve the data from the first applet via the interface for verification, and
- the first applet is precluded from communication external to the contactless card by the second applet.
