+#### What did we implement:
+We implemented a new model and table to keep users bank information and called it treasury.<br />
+After users entered their card_number or IBAN, we are sending this information to the Jibit service,<br />
+and then the Jibit Service returns the first name and last name of the real owner.<br />
+Now we can check this returned information to users' profile information to find out everything is ok.<br />
+It is worth mentioning that the steps of getting information from the Jibit and checking it with the profile are done in the background.
