Making sure transactions online are secure

If you are going to run an ecommerce business then you need to make sure all your transactions are secure. I did some research recently because I am looking to setup an online store, I found out that I need to have a SSL certificate to improve the security of my store. Basically this setup will encrypt the transactions so that the credit card user’s details don’t fall into the hands of unauthorized individuals. It just makes plain good security sense to me.
