Autofilling data based on account authentication using a contactless card

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

• identify, by a web browser, a payment field in a web page loaded in the web browser;
• determine, by the web browser, that an account application associated with an issuer of a contactless card is installed on the device;
• generate, by the web browser, based on the determination that the account application is installed on the device, a uniform resource identifier (URI) directed to the account application, wherein the URI comprises a merchant identifier parameter, a session identifier parameter, and an action identifier parameter, wherein the URI is a deep link to an authentication page of the account application;
• launch, by a mobile operating system (OS) executing on the processor, the account application based on the URI, wherein the action identifier parameter triggers the launch of the account application;
• authenticate, by the account application based on the action identifier parameter of the URI, an account associated with the contactless card based on encrypted data generated by and received from the contactless card when the contactless card is within a communications range of a communications interface of the device;
• receive, by the account application based on the authentication, a decryption result based on decrypting the encrypted data, the decryption result including payment information associated with the contactless card;
• access, by a Web View component of the account application, the web page loaded in the Web View component of the account application;
• autofill, by the Web View component of the account application, the payment information into the payment field in the web page loaded in the Web View component of the account application;
• and
• process, by the Web View component of the account application, a transaction based on the payment information autofilled into the payment field of the web page loaded in the Web View component of the account application.

A computing apparatus comprising:

• a processor;
• and
• a memory storing instructions that, when executed by the processor, cause the processor to:
• identify, by a web browser, a payment field in a web page loaded in the web browser;
• determine, by the web browser, that an account application associated with an issuer of a contactless card is installed on the apparatus;
• generate, by the web browser, based on the determination that the account application is installed on the device, a uniform resource identifier (URI) directed to the account application, wherein the URI comprises a merchant identifier parameter, a session identifier parameter, and an action identifier parameter, wherein the URI is a deep link to an authentication page of the account application;
• launch, by a mobile operating system (OS) executing on the processor, the account application based on the URI, wherein the action identifier parameter triggers the launch of the account application;
• authenticate, by the account application based on the action identifier parameter of the URI, an account associated with the contactless card based on encrypted data generated by and received from the contactless card when the contactless card is within a communications range of a communications interface of the apparatus;
• receive, by the account application based on the authentication, a decryption result based on decrypting the encrypted data, the decryption result including payment information associated with the contactless card;
• access, by a Web View component of the account application, the web page loaded in the Web View component of the account application;
• autofill, by the Web View component of the account application, the payment information into the payment field in the web page loaded in the Web View component of the account application;
• and
• process, by the Web View component of the account application, a transaction based on the payment information autofilled into the payment field of the web page loaded in the Web View component of the account application.
