Answer 2

$\mathfrak{\huge{\orange{\underline{\underline{ANSWER :}}}}}$

You must be aware of ATM cards that are used in ATM machines. ATM cards store data through magnetic strips, which are pasted on the back of these cards. Magnetic strips hold much more data than printed characters or barcodes per unit of space. These strips are not human readable and are therefore used to store confidential data. Moreover, it is almost impossible to create a duplicate copy of the cards containing such strips. Special reader machines are required to decode the encoded data stored on these magnetic strips.

The enhanced version of a card containing magnetic strips is called smart card. A smart card is embedded with the microprocessor that can hold a certain amount of personal data in its memory. The special reader machine that is used to decode the data on smart cards is known as smart card reader.
