Physical Unclonable Functions in Bank Cards or Identification Cards for Security

A system comprising:

• a substrate forming the body of a bank card;
• an EVM transaction chip on the bank card;
• a plurality of magnetized particles randomly dispersed in the substrate;
• a non-volatile memory on the EVM transaction chip that contains the magnetic field profile data measured from the magnetized particles;
• a card reader;
• and
• one or more sensors in the card reader, wherein when the bank card is inserted into the card reader the sensors measure the magnetic field in a defined area or along the defined path of the bank card.
