1. A system, comprising:

  • a mobile device comprising a processor and a memory;

    contactless card comprising a processor and a memory; and

    a server communicatively coupled to the mobile device;

    wherein the contactless card processor encrypts data associated with an account in the memory of the contactless card, wherein the contactless card generates the encrypted data using a diversified key obtained by providing a master key and a counter value stored in the memory of the contactless card as input to a cryptographic algorithm, and wherein the contactless card sends the encrypted data to the mobile device responsive to a first tap of the contactless card to the mobile device;

    wherein the server receives the counter value and encrypted data sent from the mobile device, decrypts the encrypted data using the diversified key, and sends an indication to the mobile device that the encrypted data was decrypted;

    wherein the server encrypts an account number associated with the account and sends the encrypted account number to the mobile device after the decrypting;

    wherein an application executing on the mobile device decrypts the encrypted account number to yield the account number;

    wherein the contactless card sends an expiration date associated with the account number to the mobile device responsive to a second tap of the contactless card to the mobile device;

    wherein the contactless card sends a card verification value (CVV) associated with the account number to the mobile device responsive to a third tap of the contactless card to the mobile device, wherein a tap counter counts a number of taps of the card to the mobile device, and wherein the encrypted data, expiration date, and CVV are sent by the contactless card based on the number of taps counted by the tap counter;

    wherein the application copies the decrypted account number, expiration date, and CVV as information to a clipboard on an operating system (OS) executing on the mobile device; and

    wherein the mobile device removes the clipboard information after the mobile device makes a purchase using the clipboard information or after a time threshold expires.
