Data collecting with AI

Hey guys! I'm a consultant working at a bank and recently I have a client that made a rather difficult request... They're now planning to promote a credit program, which would be based on customers' behavior when they stay in the bank. From what I'm hearing so far, they're thinking of using an AI method to do gender and facial analysis rather than asking staff members to record customer data when they're at the counter. Is this AI data-collecting a thing in Spain?
