Applets for contactless card activation

1. A method, comprising:

generating, by a first applet executing on a contactless card, a network address associated with a web page for card activation by selecting a uniform resource locator (URL) stored on the contactless card and adding dynamic data as one or more parameters of the URL;

transmitting, by the contactless card to a client device via a wireless communications interface, the network address associated with the web page;

generating, by the first applet, a cryptogram responsive to an activation request from the web page on the client device;

transmitting by the contactless card, the cryptogram to the web page via the wireless communications interface;

receiving, by the contactless card from the web page, an instruction to activate a payment applet of the contactless card; and

activating, by the contactless card, the payment applet based on the instruction.

2. The method of claim 1 , wherein the URL is one of a plurality of URLs, the method further comprising:

selecting, by the contactless card based on one or more rules, the URL from the plurality of URLs.

3. The method of claim 1 , the method further comprising:

generating, by the contactless card, the URL based on one or more rules.

4. The method of claim 1 , further comprising prior to activating the payment applet:

receiving, by the contactless card, a first request to process a payment; and

rejecting, by the contactless card, the first request based on the payment applet being in an inactive payment state.

5. The method of claim 4 , further comprising subsequent to activating the payment applet:

receiving, by the contactless card, a second request to process a payment; and

processing, by the payment applet, the second request based on the payment applet being activated.

6. The method of claim 1 , wherein the instruction to activate the payment applet is received based on a server transitioning the contactless card from an inactivated payment state to an activated payment state based on the cryptogram.

7. The method of claim 1 , wherein the contactless card transmits the network address and the cryptogram via near field communication (NFC) in respective NFC Forum Data Exchange Format (NDEF) files, and wherein activating the payment applet comprises transitioning the payment applet from an inactive payment state to an active payment state.

8. A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a processor of a contactless card, cause the processor to:

generate, by a first applet executed by the processor, a network address associated with a web page for card activation by selecting a uniform resource locator (URL) stored on the contactless card and adding dynamic data as one or more parameters of the URL;

transmit, to a client device via a wireless communications interface, the network address associated with the web page;

generate, by the first applet, a cryptogram responsive to an activation request from the web page on the client device;

transmit the cryptogram to the web page via the wireless communications interface;

receive, from the web page, an instruction to activate a payment applet of the contactless card; and

activate the payment applet based on the instruction.

9. The computer-readable storage medium of claim 8 , wherein the URL is one of a plurality of URLs, and wherein the instructions further cause the processor to:

select, based on one or more rules, the URL from the plurality of URLs.

10. The computer-readable storage medium of claim 8 , wherein the instructions further cause the processor to:

generate the URL based on one or more rules.

11. The computer-readable storage medium of claim 8 , wherein the instructions further cause the processor to, prior to activating the payment applet:

receive a first request to process a payment; and

reject the first request based on the payment applet being in an inactive payment state.

12. The computer-readable storage medium of claim 11 , wherein the instructions further cause the processor to, subsequent to activating the payment applet:

receive, a second request to process a payment; and

process the second request based on the payment applet being activated.

13. The computer-readable storage medium of claim 8 , wherein the instruction to activate the payment applet is received based on a server transitioning the contactless card from an inactivated payment state to an activated payment state based on the cryptogram.

14. The computer-readable storage medium of claim 8 , wherein the contactless card transmits the network address and the cryptogram via near field communication (NFC) in respective NFC Forum Data Exchange Format (NDEF) files, and wherein activating the payment applet comprises transitioning the payment applet from an inactive payment state to an active payment state.

15. A contactless card, comprising:

a processor; and

a memory storing instructions that, when executed by the processor, cause the processor to:

generate, by a first applet executed by the processor, a network address associated with a web page for card activation by selecting a uniform resource locator (URL) stored in the memory and adding dynamic data as one or more parameters of the URL;

transmit, to a client device via a wireless communications interface, the network address associated with the web page;

generate, by the first applet, a cryptogram responsive to an activation request from the web page on the client device;

transmit the cryptogram to the web page via the wireless communications interface;

receive, from the web page, an instruction to activate a payment applet of the contactless card; and

activate the payment applet based on the instruction.

16. The contactless card of claim 15 , wherein the URL is one of a plurality of URLs, and wherein the instructions further cause the processor to:

select, based on one or more rules, the URL from the plurality of URLs.

17. The contactless card of claim 15 , wherein the instructions further cause the processor:

generate the URL based on one or more rules.

18. The contactless card of claim 15 , wherein the instructions further cause the processor to, prior to activating the payment applet:

receive a first request to process a payment; and

reject the first request based on the payment applet being in an inactive payment state.

19. The contactless card of claim 18 , wherein the instructions further cause the processor to, subsequent to activating the payment applet:

receive a second request to process a payment; and

process the second request based on the payment applet being activated.

20. The contactless card of claim 15 , wherein the memory stores the payment applet and another applet.
