How to Accept Online Payments Safely

How to Accept Online Payments Safely

Even a cybersecurity genius would agree that when it comes to creating a secure online payment system, common sense alone is unreliable. Therefore, to be a successful eCommerce business manager or entrepreneur, you need to learn how to implement the best security practices for accepting payments via bank cards, e-wallets, and other digital methods. This knowledge will help you to protect your customers and your business from fraudsters and cybercriminals. This guide contains (in simple language) all that you need to know about accepting online payments safely.

Why do Online Payments Need to be Secure?

Security concerns are a major reason why most buyers fail to complete payments while shopping online. If your online payment system gives a sense of insecurity to your customers, they are most likely to leave your site and go to that of your competitor, and this is not good for your business. Therefore, to increase your conversion rate and sustain customer loyalty, you must improve the confidence and trust of your existing and potential customers by offering them a secure and safe payment system.

Tips to Make Payments Safe 

Use SSL/TLS for Secure Online Payments

The first things we would like you to know about accepting online payments safely and securely are the SSL (Secure Sockets Layer) and TLS (Transport Layer Security) protocols. They are both cryptographic sets of rules used to encrypt data (that is, transform human-readable data into codes) and authenticate a connection in the process of sending data over the internet. In other words, they are standard cyber security technologies that help to establish a secure connection between a website (webserver) and the web browser (client) of a visitor.

TLS is the successor of SSL – an improved version of the latter. TLS was developed to fix some security weaknesses that were in SSL. When either SSL or TLS is used to secure online data by encryption, the only way to humanly read the data is to use the correct key or cypher to decrypt it. (Note: only authorised persons with access to a decryption key can read data encrypted with SSL or TLS).

This secure online connection encrypts all messages passing through it. As a result, sensitive data, such as credit card details, are encoded before being delivered to website owners, who may then decode the data once they have it. Anyone attempting to steal the data during the transmission will only get encrypted (incomprehensible) data.

If you leave your website without SSL/TLS security, you will not be able to safely process details of transactions made through bank cards or other online payment methods, and your visitors will see a message like “Your connection is not private”. Such warnings usually make a lot of buyers leave unsecure sites. So, you need to add this security layer. You can do it by installing an SSL/TLS certificate on your web server. When installed, your website becomes secure. The visible proof of your site’s advanced security level is a padlock icon with the “https” prefix, which appears in front of your web address when a visitor uses his browser to access your site. Experts recommend using SSL/TLS to accept online payments securely, thereby reducing cyber security risks and serving your customers better.                                                                                                      

PCI Compliance in Online Payments

The Payment Card Industry Data Security Standard (PCI DSS) applies to all retailers who receive card payments (online or offline), from the world's biggest corporations to small online stores. To accept card payments, you must comply with PCI. So, what is PCI compliance? It refers to the PCI Security Standards' 12-point technological and operational framework for businesses that handle, store, or transfer card payment data. It is worth noting that each card provider has its own set of compliance, validation, and enforcement guidelines.

The particular compliance criteria you will need to fulfil will be determined by the size of your business and the number of transactions you do. Find the appropriate level for your business from the following:

  • Level 1 – Businesses that conduct more than 6 million transactions each year.
  • Level 2 - Businesses that handle 1 to 6 million transactions each year.
  • Level 3 - Businesses that handle 20,000 to one million transactions each year.
  • Level 4 - Businesses that handle fewer than 20,000 transactions each year.

Therefore, if you want to accept online payments safely, your website or web-linked database must be scanned to ascertain PCI compliance. Besides, it helps your customers to trust you with the sensitive information you receive from their cards – knowing that you can prevent security breaches and data theft.

Verify the IP and Billing Address Information

Another way to safely accept online payments is to always match the Internet Protocol (IP) address of the buyer, which helps to identify their device on the internet, with the billing address of their card. These details are provided during the transaction. If you compare the information and find that the customer is not the rightful cardholder, you can suspect any fraudulent activity and take necessary measures to stop it. Thus, this kind of confirmation can help to prevent potential fraud.

Use Strong Customer Authentication (SCA)

SCA (Strong Customer Authentication) is a method of reducing fraud and increasing the security of online payments by requiring some information from the user throughout the authentication process. Examples include asking questions relating to “something you have” (a personal computer or smartphone), “something you know” (a password or PIN), or “something you alone possess naturally” (fingerprints or voice recognition).

Use Payment Tokenization

Card tokenization can be used to accept secure payments. It encrypts sensitive payment information by transforming it into a string of completely random digits known as a "token." As a token, the data may be delivered across the internet or payment channels to complete the transaction without being revealed.

Require Strong Passwords

Cybercriminals attempt to get access to user accounts by using common names, birthdates, and dictionary word combinations. Requesting a strong password to protect client accounts can provide an extra layer of protection. If a consumer forgets their strong password, they must be able to access their account through a "forgot your password" method.

What exactly is a strong password? It is a lengthy security key that comprises uppercase, lowercase, numerical, and special characters. You can generate it yourself or use any digital tool for strong password generation. Personal information should not be included in strong passwords.

Implement 3D Secure

3D Secure is an authentication mechanism that prevents unauthorised card usage and shields e-commerce retailers from chargebacks in the case of a fraudulent transaction. To authenticate transactions, merchants, card networks, and financial institutions share information using 3D Secure.

Request the CVV

The CVV/CVC code (Card Verification Value/Code) is situated on the back of your credit/debit card on the right side of the white signature strip; it is always a three-digit code. It can be used to authenticate card transactions over the phone or online. If the credit card details have been stolen, asking for information that is only available on the card might assist businesses with validating the payment.

Monitor Fraud Continuously

A payment gateway that identifies and controls fraud is required by e-commerce retailers. A built-in fraud detection system helps to identify areas where a fraudulent transaction exists. Businesses can implement rules that deny transactions that are suspected to be too risky, or they can request permission to allow such transactions to be completed based on their position and risk tolerance.

Train Your Employees

Employees should be equipped with the information and skills necessary to detect and respond to cybersecurity threats. When the team knows the safe payment procedure, they will be better equipped to spot fraudulent conduct as it occurs and avoid data security breaches.
