POS and Data Center

If I encrypt data at the POS station and send it encrypted back to the Data Center, I don't need FW, do I?

yes, you still need to have a firewall.

The firewall helps protect your network and systems from external attacks. This includes attacks from wireless segments within your site as well as if you have an internet connection at your site.
