Project: KYC - Know Your Customer
As a financial institution regulated by the FCA, N26 has the obligation to verify the identity of all customers who want to open a N26 account. Each prospective customer has to go through a Know Your Customer (KYC) process by submitting a government-issued photo ID and a facial picture of themself to our partner.
Our goal is to find out which of the verification stages most often leads to the ‘consider’ for the result_doc column.
We can see from visualization that clear documentation have around 65% of potential customers. Around 35% have not clear documentation so we should look into that.
For ‘result_doc’ column very high correlation coefficient (0,935) has next stage of KYC:
- image_integrity_result - Asserts whether the document was of sufficient quality to verify.
For ‘result_face’ column very high correlation coefficient (0,951) has next stage of KYC:
- facial_image_integrity_result - Asserts whether the quality of the uploaded files and the content
contained within them were sufficient to perform a face comparison
These parameters have a great influence on the final KYC result.
