Secure Trading, one of the payment gateways we integrate with, have recently sent an email:
Upgrade to TLS 1.2 to avoid disruption to your payments
which says they will stop supporting TLS 1.0 and 1.1 shortly.
TLS (Transport Layer Security) is a cryptographic protocol that allows secure communications over the internet. In the case of making payments to Secure Trading the communication is between the customer’s browser and Secure Trading directly.
Your customers will need to be using an updated browser that supports TLS 1.2. If they don’t, then it is highly likely they will see an error page when they come to process the actual payment with you.
The good news is that all modern browsers already support TLS1.2. The bad news is older browsers do not.
The minimum versions that support TLS1.2 are
Apple Safari; Version 10 +
Google Chrome; Version 58 +
Microsoft Internet Explorer; Version 11
Microsoft Edge; Version 13 +
Mozilla Firefox; Version 53 +
Opera browser; Version 44 +
see https://www.securetrading.com/TLS/ for more details
We will be adding extra checking to detect if someone’s browser is below these versions, and show a warning message that they need to upgrade.
In your box office you should make sure your browsers are the latest versions.
Should a customer contact you to question why they can’t process a payment, we would advise that you ask them to ensure they are using the most up to date version of their chosen web browser.
