PIN-Code

You can change your PIN code at any time at any ATM in Switzerland (except Postomats). Avoid choosing numerical combinations that are easy to guess, e.g. dates of birth, phone numbers or car registrations. Keep your PIN code secret and never write it down, even in encrypted form.

It is therefore important that you know your PIN code and can enter it when requested, because your payments cannot be processed otherwise. Paying by PIN code is quicker, more convenient and more secure. Further information about card security
