Software testing techniques based on image recognition are disclosed. In various embodiments, a programmatically implemented image classifier is trained to recognize a screen shot image as being associated with a transaction end condition of a transaction. A test script configured to initiate an iteration of the transaction is run. A start time of the iteration of the transaction is recorded. Screen shot images are generated during performance of the iteration of the transaction to capture a series of screen shot images of at least a portion of a user interface display associated with the iteration of the transaction. The image classifier is used to find an earliest-captured image that matches the transaction end condition. A time associated with the matched image is used as a transaction end time to compute an end-to-end time to perform the iteration of the transaction.

The invention provides a secure digital card. In one embodiment, the secure digital card is coupled to a cell phone, and comprises a smart card, a secure digital card controller (SDC), a first power control circuit, and a second power control circuit. When the cell phone wants to perform a near-end payment process, the SDC controls the first power control circuit to supply a first voltage generated by a first power supply pin of a near field communication (NFC) controller to a power receive pin of the smart card. When the cell phone wants to perform a far-end payment process, the SDC controls a second power control circuit to supply a second voltage generated by a second power supply pin of the SDC to the power receive pin of the smart card.
