Locate 2-3 case studies that show how banks/financial institutions in the U.S. have implemented "Know Your Customer" (KYC) FinTech into their organization, and the cost implementations it has had for them. For each case study, we will identify who the financial institution was, what area of the banking industry they participate in (i.e. who their customers are), how they implemented/use KYC tech, and any metrics of success, struggle, or revenue gain/loss as a result of this tech.
