Q. What is OTP in credit card transaction?
Answer: One Time Password
Notes: OTP in credit card transactions stands for "One Time Password." It is a security feature used to authenticate online transactions. OTPs are typically sent to the cardholder's registered mobile number or email and are valid for a short period, enhancing security by ensuring that only the authorized user can complete the transaction. This method helps prevent fraud and unauthorized access, as each OTP is unique and can only be used once.
