Face Match (Image & Transaction ID)

---

Instead of sending two images, you can provide one face image and the Transaction ID 
of a valid Data Extraction service transaction, so we can compare the face from this 
transaction's document with the face image provided. 

The transaction ID can be found in the data extraction API response.

You can use the Face Match service by providing two face images to be compared. The result will be "True" if similar or "False" if not.
