Zencart Version: 1.50
PHP Version: 5.3.4
Operating System: Mac Snow Leopard Server

I currently use SQUARE for my business. It allows me to take a payment directly from client (card swipe) or type in card number by hand. Is there any modules or updates to Zen Cart that would allow the SQUARE setup and use? Pay Pal is $30/month. Just looking at my options for my store.

Any help would be appreciated.
