Dynamic transaction card protected by multi- factor authentication

1. A transaction card comprising:

one or more antennas;

one or more processors;

a Europay-Visa-Mastercard (EMV) chip; and

a non-transitory memory in communication with the one or more processors and storing instructions that, when executed, cause the one or more processors to perform the steps of:

receiving, via the one or more antennas, an authentication request from a user device to authenticate a user of the user device, the user logged in to the user device using one or more log-in credentials;

generating, a first response to authenticate the user of the user device, the first response comprising a digital signature; and

transmitting, via the one or more antennas, the first response associated with the user to the user device, wherein the digital signature is used to authenticate the user.

2. The card of claim 1 , wherein the transaction card further comprises:

a sensor, and

wherein the memory in communication with the one or more processors stores further instructions to cause the one or more processors to perform the steps of:

evaluating, with a sensor, the wireless connection between the transaction card and the user device.

3. The card of claim 1 , wherein:

the first response transmitted to the user device via the one or more antennas is used to authenticate the user when making a purchase.

4. The card of claim 1 , wherein:

the authentication request is encrypted, and

the first response is encrypted.

5. The card of claim 1 , wherein:

the memory in communication with the one or more processors stores further instructions to cause the one or more processors to perform the steps of:

receiving, upon personalization, preloaded card credentials.

6. The card of claim 5 , wherein:

the preloaded card credentials comprise at least a private key of a key pair, the private key used to generate the digital signature.

7. A transaction card comprising:

one or more antennas;

one or more processors; and

a non-transitory memory in communication with the one or more processors and storing instructions that, when executed, cause the one or more processors to perform the steps of:

establishing, via the one or more antennas, a first connection between the transaction card and a user device associated with a user;

receiving, from the user device via the one or more antennas, a request for information;

generating, using the one or more processors of the transaction card, a first response to the request for information, the first response used to authenticate the user of the user device and comprising a digital signature; and

transmitting, via the one or more antennas, the first response to the user device.

8. The transaction card of claim 7 , wherein:

the transaction card is capable of being used for Europay-Visa-Mastercard (EMV) transactions;

the first connection is a wireless connection, and

the memory in communication with the one or more processors stores further instructions to cause the one or more processors to perform the steps of:

evaluating, with a sensor, the wireless connection between the transaction card and the user device.

9. The transaction card of claim 7 , wherein:

the first response transmitted to the user device via the one or more antennas is used to authenticate the user when making a purchase.

10. The transaction card of claim 7 , wherein:

the memory in communication with the one or more processors stores further instructions to cause the one or more processors to perform the steps of:

receiving, at personalization, preloaded credentials, the preloaded credentials comprising a private key of a key pair, and

wherein the transaction card generates the digital signature from a private key of a key pair.

11. The transaction card of claim 10 , wherein the digital signature is used to confirm the identity of the user.

12. The transaction card of claim 7 , wherein the first response is encrypted.

13. The transaction card of claim 7 , wherein the request for information further comprises one or more log-in credentials used to log the user into the user device.

14. The transaction card of claim 7 , wherein:

the request for information is encrypted.

15. The transaction card of claim 7 , wherein:

the first connection between the transaction card and the user device is a near field communication (NFC) connection.

16. A transaction card comprising:

one or more antennas;

one or more processors; and

non-transitory memory in communication with the one or more processors and storing instructions that, when executed, cause the one or more processors to:

receive, upon personalization, preloaded credentials;

execute an Europay-Mastercard-Visa (EMV) transaction by:

receiving EMV data at the transaction card; and

generating an EMV response to the EMV data;

authenticate a user by:

receiving, from a user device via the one or more antennas, a request for authentication data,

generating a first response to the request for authentication data using the preloaded credentials; and

transmitting, via the one or more antennas, the first response to the user device.

17. The transaction card of claim 16 , wherein the memory in communication with the one or more processors stores further instructions to cause the one or more processors to:

establish, via the one or more antennas of a transaction card, a first near field communication (NFC) wireless connection between the transaction card and a user device.

18. The transaction card of claim 16 , wherein the first response is used to authenticate the identity of the user in connection with a transaction.

19. The transaction card of claim 16 , wherein the first response is used for step-up authentication.

20. The transaction card of claim 16 , wherein the preloaded credentials comprise a private key of a key pair.

21. The transaction card of claim 16 , wherein the private key is used to generate a digital signature.

22. The transaction card of claim 16 , wherein the first response comprises the digital signature.
