Square’s Keith Rabois also revealed a number of growth statistics for the company, including that the payments service is now processing $2 billion in payments volume per year. To date, Square has been activated by 800,000 merchants which is up from 500,000 card readers shipped in May. Rabois says that Square’s merchants are now 10% of the reach of the Visa/MasterCard world.

Back in May, my Mom called and said she processed her first payment at a farmers market (she makes all natural dog products) with Square. Even though their growth has been impressive over the past couple of years, it really wasn’t until then that I realized that Square has got something here.
