No one can force your to share information. Let's say your PIN code is 1324, and you suffer from stress induced transposia (just made that up). Every time you are asked to say or share your PIN code, you get stresses & use 1234, even though you meant to use 1324. There's no way make you say the correct PIN code. In a more realistic example, what are you going to do to someone who simply forgot their PIN code?
