Mobile enrollment using a known biometric

1. A system for biometric identification, comprising:

at least one non-transitory storage medium that stores instructions; and

at least one processing unit that executes the instructions to:

obtain a first digital representation of a biometric for a person;

store the first digital representation of the biometric for the person for subsequent identification;

obtain a second digital representation of a biometric for the person, the first digital representation of the biometric for the person not being identical to the second digital representation of the biometric for the person;

upon identifying the person using the first digital representation of the biometric for the person, store the second digital representation of the biometric for the person for subsequent identification;

obtain a third digital representation of a biometric for the person; and

attempt to identify the person by comparing the third digital representation of the biometric for the person to the second digital representation of the biometric for the person.

2. The system of claim 1 , wherein the at least one processing unit attempts to identify the person by comparing the third digital representation of the biometric for the person to the second digital representation of the biometric for the person and the first digital representation of the biometric for the person.

3. The system of claim 1 , wherein the first digital representation of the biometric for the person corresponds to a fingerprint.

4. The system of claim 1 , wherein the first digital representation of the biometric for the person corresponds to a palm-vein scan.

5. The system of claim 1 , wherein the at least one processing unit identifies the person to obtain stored financial information for the person.

6. The system of claim 5 , wherein the stored financial information for the person includes a financial account number.

7. The system of claim 1 , wherein the second digital representation of the biometric for the person is obtained from a palm-vein scanner.

8. The system of claim 1 , wherein the at least one processing unit determines a degree of certainty that the second digital representation of the biometric for the person corresponds to the person.

9. The system of claim 1 , wherein the at least one processing unit verifies an identity associated with the person.

10. A system for biometric identification, comprising:

at least one non-transitory storage medium that stores instructions; and

at least one processing unit that executes the instructions to:

identify a person using a first digital representation of a biometric for the person after receiving a second digital representation of a biometric for the person, the first digital representation of the biometric for the person not being identical to the second digital representation of the biometric for the person;

store the second digital representation of the biometric for the person for subsequent identification; and

attempt to identify the person by comparing a third digital representation of a biometric for the person to the second digital representation of the biometric for the person.

11. The system of claim 10 , wherein the at least one processing unit stores financial account information associated with the first digital representation of the biometric for the person.

12. The system of claim 11 , wherein the at least one processing unit associates the financial account information with the second digital representation of the biometric for the person.

13. The system of claim 10 , wherein the first digital representation of the biometric for the person and the second digital representation of the biometric for the person have a same modality.

14. The system of claim 10 , wherein the at least one processing unit attempts to identify the person by comparing the third digital representation of the biometric for the person to the second digital representation of the biometric for the person and the first digital representation of the biometric for the person.

15. A system for biometric identification, comprising:

at least one non-transitory storage medium that stores instructions; and

at least one processing unit that executes the instructions to:

store a first digital representation of a biometric for a person for performing identifications;

obtain a second digital representation of a biometric for the person;

upon determining the second digital representation of the biometric for the person is different from the first digital representation of the biometric for the person, store the second digital representation of the biometric for the person for subsequent identification;

obtain a third digital representation of a biometric for the person; and

attempt to identify the person by comparing the third digital representation of the biometric for the person to the second digital representation of the biometric for the person.

16. The system of claim 15 , wherein the at least one processing unit obtains information from a token for the person.

17. The system of claim 16 , wherein the token corresponds to a financial account.

18. The system of claim 16 , wherein the information comprises a financial account number.

19. The system of claim 15 , wherein the at least one processing unit attempts to identify the person by comparing the third digital representation of the biometric for the person to the second digital representation of the biometric for the person and the first digital representation of the biometric for the person.

20. The system of claim 15 , wherein the at least one processing unit attempts to identify the person as part of the person purchasing goods or services.
