Secure-transaction notifications
To facilitate conducting a secure transaction via wireless communication between a portable electronic device (such as a smartphone) and another electronic device (such as a point-of-sale terminal), the portable electronic device may, after a final command is received from the other electronic device, determine a unique transaction identifier for the secure transaction. In particular, the final command may be specific to an applet, stored in a secure element in the portable electronic device, which conducts the secure transaction. The secure element may generate the unique transaction identifier based on financial-account information associated with the applet, which is communicated to the other electronic device. Next, the secure element may provide, to a processor in the portable electronic device, an end message for the secure transaction with the unique transaction identifier.
1. A method of conducting a wireless transaction by an electronic device, the method comprising:
conducting, using an applet securely stored in the electronic device, a secure transaction with a second electronic device;
generating, based at least in part on financial account information associated with the applet, a unique transaction identifier associated with the secure transaction; and
providing the unique transaction identifier to a processor in the electronic device.
2. The method of claim 1 , wherein the unique transaction identifier is generated following a final command for the secure transaction.
3. The method of claim 2 , further comprising:
receiving the final command for the secure transaction from the second electronic device.
4. The method of claim 1 , wherein the unique transaction identifier comprises at least a portion of a secure hash of the financial account information associated with the applet.
5. The method of claim 1 , wherein:
the applet is stored in a secure element of the electronic device; and
the unique transaction identifier is generated in the secure element.
6. The method of claim 1 , wherein generating the unique transaction identifier further comprises:
generating the unique transaction identifier such that it can be independently generated by a third electronic device based at least in part on information associated with the secure transaction.
7. The method of claim 1 , further comprising:
associating an item of receipt information with the unique transaction identifier.
8. The method of claim 1 wherein the unique transaction identifier comprises information indicating when the secure transaction occurred.
9. A secure element for use by an electronic device, comprising:
a memory; and
one or more processors communicatively coupled to the memory and configured to:
conduct, by an applet securely stored in the secure element, a secure transaction with a second electronic device;
generate, based at least in part on financial account information associated with the applet, a unique transaction identifier associated with the secure transaction; and
provide the unique transaction identifier to another processor in the electronic device.
10. The secure element of claim 9 , wherein the unique transaction identifier is generated following a final command for the secure transaction.
11. The secure element of claim 9 , wherein the unique transaction identifier comprises at least a portion of a secure hash of the financial account information associated with the applet.
12. The secure element of claim 9 , wherein the one or more processors are further configured to:
generate the unique transaction identifier such that it can be independently generated by a third electronic device based at least in part on information associated with the secure transaction.
13. The secure element of claim 9 , wherein the one or more processors are further configured to:
associate an item of receipt information with the unique transaction identifier.
14. The secure element of claim 9 , wherein the unique transaction identifier comprises information indicating when the secure transaction occurred.
15. A non-transitory computer-readable medium storing instructions that, when executed by a processor of an electronic device, cause the processor to perform operations, the operations comprising:
conducting a secure transaction with a second electronic device;
generating, based at least in part on financial account information associated with an applet securely stored in the electronic device, a unique transaction identifier associated with the secure transaction; and
providing the unique transaction identifier to a second processor in the electronic device.
16. The non-transitory computer-readable medium of claim 15 , wherein the unique transaction identifier is generated following a final command for the secure transaction.
17. The non-transitory computer-readable medium of claim 15 , wherein the unique transaction identifier comprises at least a portion of a secure hash of the financial account information associated with the applet.
18. The non-transitory computer readable medium of claim 15 , wherein the operations further comprise:
generating the unique transaction identifier, wherein the unique transaction identifier can be independently generated by a third electronic device based at least in part on information associated with the secure transaction.
19. The non-transitory computer-readable medium of claim 15 , wherein the operations further comprise:
associating an item of receipt information with the unique transaction identifier.
20. The non-transitory computer-readable medium of claim 15 , wherein the unique transaction identifier comprises information indicating when the secure transaction occurred.
