How to check if your payment form is encrypted


1. HTTPS and lock in address bar

The first and easiest way is to check if the site address starts with https\://. If a lock icon is displayed in the browser, it means that SSL/TLS encryption is used. However, it is worth remembering: the presence of a lock in itself does not guarantee the honesty of the casino, it only indicates a secure connection.

2. View site certificate

To verify reliability:
  • press the lock in the address bar;
  • Verify certificate information (issued to, expiration date, issuing organization)
  • Verify that the certificate is issued by a known certification authority (for example, DigiCert, Sectigo, GlobalSign).

An expired or self-signed certificate may indicate an unsafe resource.

3. Verification of payment form encryption

The payment form must be built in through a secure payment gateway (for example, Visa, Mastercard, AmEx or certified processing). Signs of proper integration:
  • the form opens in a secure iframe with the address of the payment provider;
  • card data is not stored on the casino website, but is transmitted directly to the processor;
  • There is no clear data transfer in the page code.

4. Using 3D Secure

If, when paying, the system asks for a one-time password, SMS or push notification, then an additional level of protection is connected. This indirectly confirms the correct operation of encryption and the participation of the issuing bank in the verification of the transaction.

5. Verification tools

The player can independently check the security level:
  • services like SSL Labs show encryption strength and server configuration;
  • Browser-based developer tools make sure the form uses HTTPS requests.
  • browser extensions can signal mixed content (partially unencrypted elements).

6. Conclusion

To make sure that the form of payment in the online casino is really encrypted, just check HTTPS, the validity of the SSL certificate, the address of the payment gateway and the presence of 3D Secure. This minimizes the risk of data interception and increases trust in the platform.
