Life has become easier with Electronic Funds Transfer (ETF). No matter if you are shopping, booking tickets or doing any other work, one can save hassles of keeping a large amount of paper currency. Just take out your credit or debit card and fulfill your sudden money requirement. Have you ever wondered how these transactions actually happen? No!!! Check out your personal identification number (PIN) and try to figure out the logic behind it. PIN is basically a secret numeric relationship between a user and a system that provides authentic entry of a user into a system. PIN is used to verify the user’s identity with a system to ensure the safety of money related transactions. Generally, a PIN can be blocked after the failure of three attempts and all the other details can be freezed too. So, next time while using your debit or credit card, be careful with your PIN as it is the gateway to your bank account.
