One of the most important things in e-payment is security.

The whole point of the online payment process is to provide the e-merchant with the ability to manage the transaction in a secure environment.

What makes an e-transaction secure?

The payment gateway can provide e-shops with fraud prevention tools, such as address verification systems, 3DS authentication, systems for monitoring and preventing suspicious and risky transactions, and operational processes that significantly reduce fraud risks if used in combination.

Additionally, payment processors affect the security compliance process, as they must be certified to the PCI-DSS standard.

Today, several standards and regulations exist to protect e-merchants and buyers from online payment fraud.

  • The first layer of protection is from payment card security standards such as the 3D Secure standard. Additionally, to accept credit card payments online, e-merchants and their payment gateways need to be PCI-DSS compliant.
  • In addition to PCI compliance, e-merchants selling in Europe who wish to accept card payments must also comply with payment regulations – PSD2 (Payment Services Directive), which enforces strong authentication mechanisms in online payment processes, such as SCA (Strong Client Authentication).
  • Apart from payment regulations, online transactions are also covered by data protection regulations. Merchants in N. Macedonia need to comply with GDPR – a regulation that regulates how consumer data privacy is handled and directly affects the payment process.

Regarding the security of specific payment methods:

  • Credit cards are among the types of payment that are considered the safest for online transactions, being covered by so many regulations, including 3DS authentication and PSD2 in Europe as mentioned previously.
  • E-wallets offer strict security, since their payment-only approach does not include the sharing of the user’s bank details with the e-merchant and their paid portal.

How to make secure online payments as an e-seller?

As an e-seller, there are a number of tactics you can implement to ensure the security of your e-payments. In addition to reminding consumers about the benefits of online payments, you will teach them how to make online payments safely and what makes your brand stand out in this field.

  1. Make users feel safe on your site or your application
    You use an SSL/TLS certificate that will automatically display a lock icon – a sign that buyers are connecting to a secure transaction, which is located in the web address section of the browser (eg Google Chrome) and set your payment method icons users recognize and trust them, like Visa, Mastercard, Diners, etc. (most often in the footer of web pages).
  2. Users should be in the process
    Communicating with users about the status of their orders, delivery details and previous orders makes the entire online payment process more transparent and resistant to fraud attempts.
  3. Review your orders
    To keep track of your orders, take action to review them periodically. In this way, you will find out if there is any suspicious activity or fraud attempts on your systems.
  4. You are using a paid portal with an implemented 3D Secure protocol
    Not only does it provide an additional layer of security with two-factor authentication, it also protects e-merchants from unwanted return charges.
