When you are running an online retail site you need to be able to offer your customers proof that all of their personal information and credit card data is fully protected at all points during and after their transaction is completed. The best way to do this is by using a certification authority that can provide you with a digital certificate and the highest level of data encryption.
When you start looking for a certification authority, you need to find one that uses a minimum of 128 bit SSL encryption to protect all of the data being transferred. If you can find one that has several verifiable years in the business like Digi-Sign, you will find that you can offer every one of your customers the very latest in secure payment technology, a fact that will give them the level of confidence needed to spend their money on your site.
