TLS (Transport Layer Security) keeps your data safe when you send it from one system to another and protects it from attackers. There are three versions of TLS:
- TLS 1.0
- TLS 1.1
- TLS 1.2
The Payment Card Industry Security Standards Council no longer considers TLS 1.0 to be secure. You should use either TLS 1.1 or TLS 1.2 in your business.
How does my business use TLS?
Your business uses TLS to protect the information that you send when running transactions on your card terminals, POS devices, e-Commerce platforms, or back office tools. Our products and services use the right version of TLS to protect transaction information. However, you must make sure that you use either TLS 1.1 or TLS 1.2 on your POS devices, e-Commerce platform, or back office tools.
The following diagrams show how your business uses TLS depending on how you run transactions:
Using Genius and a POS to perform transactions
Your POS, your Genius device, and the Payments Platform use TLS to protect the data they send. In this scenario, Genius and the Payments Platform send data using either TLS 1.1 or TLS 1.2. You must make sure that your POS is using TLS 1.1 or 1.2, otherwise you will be unable to run transactions. To find out what version of TLS your POS uses, contact your POS provider.
Using an integrated POS to perform transactions
Your POS and the Payments Platform use TLS to protect the data they send. You must make sure that your POS is using TLS 1.1 or 1.2, otherwise you will be unable to run transactions. To find out what version of TLS your POS uses, contact your POS provider.
Using a credit card terminal to perform transactions
Your credit card terminal and the Payments Platform use TLS to protect the data they send. You must make sure that your credit card terminal is using TLS 1.1 or 1.2, otherwise you will be unable to run transactions. To find out what version of TLS your card terminal uses, contact our Customer Support Team.
Using the Payments Portal
The Payments Portal and the Payments Platform use TLS to protect the data they send. You must make sure that your PC or mobile device and your web browser is using TLS 1.1 or 1.2, otherwise you will be unable to access the Payments Portal.
