SYSTEM, METHOD, AND APPARATUS FOR UPDATING AN EXISTING DYNAMIC TRANSACTION CARD

摘要

A system for securely updating an electronic transaction card held by an account holder with an additional account and/or account data. A dynamic transaction card may be securely updated with an additional account by using pre-stored shell data and/or inactive data, whereby the pre-stored shell data may be populated using data received from an issuer system and/or the inactive data may be activated via an activation signal received from an issuer system. A backend server may determine, via a fraud determination, expiration determination, and/or user-request, that new account data should be transmitted to an account holder. The dynamic transaction card may receive the data associated with a notification, update a display, instruct an EMV applet to use a key associated with a received EMV key identifier for signatures, and/or update any additional data stored on the dynamic transaction card.

1. A dynamic transaction card comprising:
an energy storage device that provides power to the dynamic transaction card; an antenna that enables an account holder mobile device to connect to the dynamic transaction card; a EuroPay-MasterCard-Visa (EMV) chip in communication with an EMV microprocessor, wherein the EMV microprocessor includes inactivated account data and an encryption key that, upon receiving an activation signal via the antenna, executes a pre-loaded script to activate the inactive account data and the inactive encryption key thereby creating active account data and an active encryption key; and data storage storing pre-stored account data that associates multiple accounts related to multiple financial institutions with the dynamic transaction card.
