Privacy and security of information, specifically regarding financial data and payments, are essential for customer satisfaction. The first ever secured online payment was made in 1994 and it turned out to be successful. Internet Shopping Network and Net Market introduced it. The Payment industry is growing significantly with the use of new emerging products like E-wallets, QR codes, NFC, and many more.


With this, payment security concerns are also increasing. Security is not a product but a process. It is the accumulation of processes for keeping our customers safe and secure. According to a study by Globe Newswire, payment fraud via mobile devices was predicted to be more than 50% for the 2nd quarter of 2021. This suggests that even after so many advancements in the digital payment world, security concerns are still prevalent.

What is Payment Security?

Payment security is the process of the various steps taken by banks, financial institutes, or businesses. This process ensures their customers' data are protected from security breaches. Security breaches may include privacy, data leak, or stolen money. Generally, it’s important to adhere to the rules, regulations, and security aspects for your customers.

The security of payment comes with multiple layers and may have various requirements based on the kind of business. These multiple layers of security are required because if any breach occurs in the security, it’s you who will be held accountable. If these layers are implemented, you’ll be able to save yourself from lawsuits and unsatisfied transactions.

Types of Payment Security


Remember, the token that you receive in return for money in the casinos or gaming zones? These tokens are valid in that particular casino or gaming zone only! It has no value outside its premises.


Similar is with online payment tokenization, but instead of money, here the token is created for a cardholder’s sensitive information such as name, card details, address, or bank account details.

For instance, if your card number is 12345678910, tokenization will convert the card number into a unique alphanumeric token number. This number can be used only once. These tokens have no meaning once they are utilized for transactions.

So, here there are no chances of stealing identity or data breaches. This helps you to keep transactions safe and secure. These transactions can be made through credit card information stored in e-wallets, POS, or any other e-commerce solutions.

Biometric Payment System

Biometric payment is a Point-of-Sale Technology that uses authentication of biometrics based on the physical characteristics of users such as a finger, face, eye, vein, voice, etc. This biometric system helps in knowing the identity of the user and in deducting the payments from their bank account.


The most common secure payment method used for biometric authentication is the fingerprint scan. The system uses 2-factor biometric authentication. A finger scan is used instead of ‘cards to swipe’, and then the user has to type in the Personal ID Number (PIN) for payment deduction from the account.

The most used biometric payment methods other than fingerprint scans are Iris Scan, Retina Scan, Voice Scan, Facial Recognition, and Palm Geometry scan. Ear scans, signature matches, and DNA match options are available in rare cases.

Address Verification Service (AVS)

Address verification service (AVS) is a system specially made for fraud protection. It is an online payment security solution designed and provided by credit card processors and banks to detect any suspicious activities in credit card transactions and prevent payment fraud.


The address verification service system checks the address given by the cardholder with the address in the records of the bank. And then the secure payment processor sends a response to the system and the payment is accepted or rejected based on this response.

If the AVS system is used correctly, it can limit the digital payment fraud faced by so many customers. This will be beneficial to you, as your customers will stay retained.

3D Secures

3D Secure (3DS) is an authentication tool designed to avoid the illegal or unauthorized use of cards in card-not-present transactions. 3DS helps in adding an extra protection layer to the payment experience. And there is a 2-step verification on every transaction making it extra secure.


No payments can be done without the authentication of the user. This authentication is done either through a personal ID number (PIN) or a one-time password (OTP).

There are three parties involved in this verification process: Banks, Issuing Banks, and processing technology. The essential point to note is that the liability of the payment security is shifted from you to the bank on the successful verification of the transaction.

How to protect online payments for your customers?

The types of payment security, as discussed above, can be useful for preventing security-related issues. However, certain standards and processes can help make secure online payments for your customers.

Maintain Security Standard - PCI DSS

To protect the online payment processes for your customers, your first step should be to maintain the required and necessary security standards. One of the major security standards which, if followed, can help you keep your customers' cards or transactions safe is the ‘Payment Card Industry Data Security Standard (PCI DSS).

PCI DSS was developed in 2004 by Visa, MasterCard, Discover Financial Services, American Express, and JCB. These standards are made for any entity that accepts, processes, transmits, and stores the details of cards. Its main motto is to make online payments via cards more secure and fraud less.

Find the Right Payment Gateway

Protecting your customers’ sensitive data is very important. And payment gateway has a huge contribution to online payment security. So, finding the right payment gateway provides you with the right security required to accept the payments.

For choosing the right payment gateway, you must give priority to how it keeps the transactions secured, the tools used, the security standards followed, and who can access the payment data. You can also consult with industry experts for the same.

Encrypt Data through SSL and TLS

Online payment security requires encryption to keep the data and access to sensitive information secured. For this, Secure Socket Layer (SSL) and Transport Layer Security (TLS) can be implemented.

SSL helps in encrypting the information, to protect the payment details and sensitive information. TLS helps protect the privacy and security of data for online payment communications.

Deploy online secure money transfer system with Secure Electronic Transaction

Secure Electronic Transaction (SET) is the online secure payment system introduced by VISA and MasterCard. This system aims at maintaining the security of all the parties involved in online payments for a secure online money transfer.

It works on vital functions such as authentication of merchants and cardholders, maintaining payment protocols, keeping a check on security procedures, and keeping the payment information confidential.
