Information such as expiry date of your credit or debit card ,its number ,and your full name are prominently displayed on the card .your name would be known to most people,but you should not share any others. These details are needed to carry out online transaction .and this information is the first level of security .without access to it ,there is no way to misuse your card .safeguard these details and don't reveal them to any unauthorized person.
Every debit and credit card has a card verification value or CVV number on it reverse .this number is vital for completing online transactions. this is clearly printed on your card ,and you should not share it with anyone
If you use net banking or credit cards for online transactions, you know that the transaction cannot go through without confidential details such as your customer identification number, cards details and the password .while other details, such as those on your card ,may have been compromised without your knowledge; the password is completely under control. Do not tell others about and just to be sure,change the password at regular intervals
Personal identification number (PIN)of credit and cards are needed at ATMS and merchant establishments to withdraw money and complete transaction . it is a secret number and a vital security feature. Never share it and be careful while using it at ATMs and POS machine to ensure that nobody is looking over your shoulder to steal this secret from you.
One -time password (OTP)are a authentication tool,which make your online transactions more secure .when you purchase anything online using your card, not banking of your e-wallet ,an OTP is generated and is usually sent to your registered mobile number ,this is applicable only if you have successfully cleared the other security challenges.
Should your confidential data be compromised, this is your last defence .if you share it with someone else, the OTP may be used to clean out thousands from your account, instead of the RS500 debit you may be expecting.
Therefore, always be suspicious if anyone asks for it .your bank or financial service provider never or will.
