System, method, and apparatus for updating an existing dynamic transaction card
A system for securely updating an electronic transaction card held by an account holder with an additional account and/or account data is described. 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 a mobile device.
1 . A method for updating account information for a smart card, the method comprising:
receiving, at a microprocessor of the smart card and via an antenna in communication with the microprocessor, new account data and an associated encryption key identifier from a mobile device, the new account data and the associated encryption key identifier provided by a backend system and relayed to the smart card via the mobile device;
executing, via the microprocessor, a pre-loaded script to update account data with the new account data;
associating, via the microprocessor, a pre-stored encryption key with the new account data using the associated encryption key identifier thereby creating updated account data; and
transmitting an operation request associated with the updated account data, wherein the operation request is encrypted with the pre-stored encryption key.
2 . The method of claim 1 , wherein the new account data is received in response to fraud detection associated with an operation of the smart card.
3 . The method of claim 2 , wherein the fraud detection is calculated based on a fraud score that is based at least in part on a connection between the mobile device and the smart card.
4 . The method of claim 3 , wherein the operation is a financial transaction, and wherein the fraud score is further calculated based on at least one of a transaction amount, a merchant identifier, or transaction statistics associated with the financial transaction.
5 . The method of claim 4 , wherein the transaction statistics include at least one of:
a number of transactions that occur without pairing the smart card to the mobile device,
a percentage of transactions that occur without pairing the smart card to the mobile device, a number of transactions approved without pairing, or
a percentage of transactions approved without pairing the smart card to the mobile device.
6 . The method of claim 1 , wherein the operation is a financial transaction, and wherein the operation request is transmitted to a point of sale (PoS) terminal via a wireless transmission.
7 . The method of claim 6 , wherein the wireless transmission is completed via the antenna in communication with the microprocessor.
8 . The method of claim 1 further comprising transmitting, via the antenna, a notification to the mobile device, the notification including a confirmation to activate, at a backend system, an account associated with the updated account data.
9 . A smart card comprising:
an antenna;
a microprocessor; and
a memory storing instructions that, when executed by the microprocessor, causes the smart card to:
receive, at the microprocessor and via the antenna, new account data and an associated encryption key identifier from a mobile device, the new account data and the associated encryption key identifier provided by a backend system and relayed to the smart card via the mobile device;
execute a pre-loaded script to update account data with the new account data;
associate a pre-stored encryption key with the new account data using the associated encryption key identifier thereby creating updated account data; and
transmit an operation request associated with the updated account data, wherein the operation request is encrypted with the pre-stored encryption key.
10 . The smart card of claim 9 , wherein the new account data is received in response to fraud detection associated with an operation of the smart card.
11 . The smart card of claim 10 , wherein the fraud detection is calculated based on a fraud score that is based at least in part on a connection between the smart card and the mobile device.
12 . The smart card of claim 11 , wherein the operation is a financial transaction, and wherein the fraud score is further calculated based on at least one of a transaction amount, a merchant identifier, or transaction statistics associated with the financial transaction.
13 . The smart card of claim 12 , wherein the transaction statistics include at least one of:
a number of transactions that occur without pairing the smart card to the mobile device,
a percentage of transactions that occur without pairing the smart card to the mobile device, a number of transactions approved without pairing, or
a percentage of transactions approved without pairing the smart card to the mobile device.
14 . A mobile device comprising:
an antenna;
a microprocessor; and
a memory storing instructions that, when executed by the microprocessor, causes the mobile device to:
receive, from a backend system, a notification identifying a usage event for a smart card using initial card data associated with the smart card, the usage event indicating that a change in the initial card data is needed;
receive an indication of a request to receive new card data for the smart card;
receive the new card data and an encryption key from the backend system;
pair, via the antenna, with the smart card;
transmit the new card data and the encryption key to the smart card;
receive, from the smart card, a confirmation of a successful account update on the smart card using the new card data; and
transmit, to the backend system, an indication of the confirmation to activate a new account associated with the new card data.
15 . The mobile device of claim 14 , wherein the usage event is a financial transaction.
16 . The mobile device of claim 15 , wherein the usage event is a financial transaction which occurred using the smart card at a point of sale (PoS) terminal.
17 . The mobile device of claim 16 , wherein the usage event is a fraud detection for the financial transaction using the initial card data.
18 . The mobile device of claim 17 , wherein the fraud detection is calculated based on a fraud score that is based at least in part on a connection between the mobile device and the smart card.
19 . The mobile device of claim 18 , wherein the fraud score is further calculated based on at least one of a transaction amount, a merchant identifier, or transaction statistics associated with the financial transaction.
20 . The mobile device of claim 19 , wherein the transaction statistics include at least one of:
a number of transactions that occur without pairing the smart card to the mobile device,
a percentage of transactions that occur without pairing the smart card to the mobile device, a number of transactions approved without pairing, or
a percentage of transactions approved without pairing the smart card to the mobile device.
