In the age of digital transactions, ensuring the security of credit card transactions is paramount. One key element in this security framework is the OTP or One-Time Password. This unique code acts as a safeguard, providing an additional layer of protection for credit card users. This article delves into the significance, usage, and nuances of OTPs in credit card transactions.
How are OTPs used in credit card transactions?
An OTP is a dynamic, time-sensitive code sent to the cardholder's registered mobile number or email address during a credit card transaction. It serves as a temporary authentication measure, ensuring that only the rightful cardholder can complete the transaction. To complete a purchase, the user must enter the OTP within a specified timeframe.
Why is it necessary to use an OTP for a credit card transaction?
The use of OTPs in credit card transactions serves several crucial purposes:
- Enhanced security: OTPs add an extra layer of security, making it significantly harder for unauthorised individuals to misuse credit card details.
- Authentication: By entering the OTP, users verify their identity and validate the transaction, reducing the risk of fraudulent activities.
- Dynamic code: The time-sensitive nature of OTPs ensures that even if intercepted, the code becomes useless after a short period, thwarting attempts at unauthorised access.

Disadvantages of using OTP in credit card transactions
While OTPs may prove to be a robust way to ensure all credit card transactions are authentic, there are some disadvantages as well that you must be aware of.
- Dependence on communication channels: OTPs are typically sent via SMS or email, making users dependent on reliable communication channels, which may pose challenges in the case of connectivity issues.
- Potential for SIM swapping: In rare cases, attackers may attempt SIM swapping to gain access to OTPs, emphasising the importance of additional security measures.
