C#
Passport Checker
While working at CRO, clients had requested at system to check the valitdity of inputted passports while doing wider Anti money laundering (AML) checks. This feature was added onto the portal where customers carry out AML checks and I wrote the back end code for this in C#. My function took in an argument of the second line of the machine readable zone (MRZ) of the passport as well as information on the ID such as the name, DOB, Gender and nationality. My function then checked that the above data presented on the passport matched the information in the MRZ using a series regular expressions. It then calculated all the correct check codes and matched them up to the checkcodes in the MRZ. The purpose of this check was to help to validate the passport and also ensure the holder of the passport has not tampored with information on the photo page such as name, DOB, Gender and nationality.
