Banks have begun to implement new technologies to help verify who the customer is, though the new GDPR rules in Europe could complicate usage; the General Data Protection Regulation, which will restrict how companies collect and store data, allows for customers to ask for their data to be removed and non compliance results in huge fines; banks have started to slowly add new technology but they are still figuring out where to limit storage; new companies are trying to sell services into bank that allow them to collect information but store it in a certain way to be compliant; with new technology being developed so rapidly, governments need to ensure they keep up with innovation and clearly tell the market how to comply.
