Method and system for obtaining and using identification information

A computer system for identifying a user for transactions, comprising:

• a client interface configured to, during a first transaction, receive an image of an identification document of a user from a device of the user and to receive a device ID of the user's device;
• an identification credential extractor configured to extract identification credentials of the user from the image;
• an identification credential manager configured to, during the first transaction, store both the identification credentials of the user and the device ID, wherein the device ID is associated with the identification credentials of the user;
• and
• a third-party interface configured to, during the first transaction, transmit the identification credentials to a third party to identify the user,
• wherein the client interface is further configured to, during a subsequent transaction, receive the device ID, and the identification credential manager is further configured to, during the subsequent transaction, retrieve the identification credentials of the user based on the received device ID,
• wherein the third-party interface is further configured to, during the subsequent transaction, transmit the retrieved identification credentials to identify the user.

A computerized method of identifying a user for transactions, comprising:

• receiving identification credentials of the user during a first transaction with a first party, wherein the identification credentials are obtained using a device of the user;
• receiving a device ID of the user's device;
• storing the identification credentials of the user and the device ID of the user's device on a server, wherein the device ID is associated with the identification credentials of the user;
• during a subsequent transaction with a second party, receiving the device ID of the user's device;
• retrieving the identification credentials of the user stored on the server based on the device ID received during the subsequent transaction;
• and
• transmitting the retrieved identification credentials to the second party to identify the user for the subsequent transaction.

A computerized method of identifying a user for transactions, comprising:

• during a first transaction with a first party, acquiring an image of an identification document of the user from an image acquisition module of a device of the user;
• determining a device ID of the user's device;
• transmitting the image of the identification document of the user along with the device ID to a server to identify the user for the first transaction;
• during a subsequent transaction with a second party, transmitting the device ID to the server to identify the user for the subsequent transaction;
• and
• receiving confirmation of identification of the user based on the transmitted device ID during the subsequent transaction with the second party.

A device for identifying a user for transactions, comprising:

• an image acquisition module configured to capture an image of an identification document of the user;
• a device ID determiner configured to determine a device ID of the device;
• and
• a communication module configured to transmit the image along with the device ID to a server to identify the user for a first transaction with a first party, wherein the communication module is further configured, during a subsequent transaction with a second party, to transmit the device ID to the server to identify the user for the subsequent transaction.
