Why won't my web browser allow me to enter a credit card securely?
Simple In/Out utilizes Stripe for secure credit card payments. Stripe is one of the leaders in the payment industry. Working with them enables Simple In/Out to have advanced fraud detection and security protections.
If you receive a message on our credit card entry website that you are "Unable to Establish a Secure Connection," this means your web browser was unable to connect to Stripe's system via a secure HTTPS connection. There are two likely causes.
Cause #1: Your firewall may be blocking access
Encrypting your credit card information happens directly on Stripe's secured systems. Simple In/Out never sees or stores your credit card information. Because of this design, your web browser needs to be able to contact Stripe's system directly.
If you have a corporate or government firewall, this could potentially block access to Stripe's system. Because all firewall hardware/software is different, we can't aid in troubleshooting your specific setup. The URLs that should be allowed are any from stripe.com.
Cause #2: Your web browser has not enabled TLS 1.2.
TLS 1.2 is a specification for more secure connections. It is required to be PCI compliant as of June 30, 2018. If your web browser has disabled this feature, then this error occurs. Below are instructions to fix this in Internet Explorer.
First, click the settings menu in the upper-right and then click Internet options.
Click the Advanced tab and scroll down until you see the "Use TLS 1.2" checkbox. Make sure to check the checkbox and click the "Apply" button in the lower-right.
