100% Secure Shopping Website At polysupplies we take security very seriously. Our secure server software encrypts (scrambles) all your card and cardholder details using a 128-bit encryption. This ensures that the information is stored and sent across the internet encrypted. You can tell that the pages you are using are secure because a padlock symbol / key is seen in the bottom bar of your screen. You will also notice that the address in the address bar changes from http:// to https:// (which stands for Hyper Text Transmission Protocol Secure). This indicates that the secure sockets layer stand is being used. We are registered under the Data Protection Act and therefore follow strict guidelines and procedures when storing or disclosing your information.
