I've seen fingerprint authentication fooled for the cost of a camera and an inkject printer.
Or for the cost of a piece of sellotape (to lift a fingerprint), a small piece of photo-resist-coated PCB material, standard etchant, and a blob of silicone rubber. Which method has the advantage that it does not need any connivance from its victim. It's just a slight modification of the long-known method for putting a random fingerprint on an incriminating object. (Pray you have a good alibi if it's your print they lift )
Or for no cost at all. A brutal criminal will just cut off your finger(s) and leave you tied up while he empties your bank account. Mercedes used to sell cars that used the owners finger instead of a key. Until South African carjackers started cutting drivers' fingers off. Mind you, that was better than being shot dead and then having your fingers hacked off. Or vice versa. No way I'd drive any car except a rust-bucket in a country like that. Safer still to not go there at all.
No way am I ever going to carry a financial instrument that uses part of my body as a key.
