Soon, every other barista in Manhattan  will be able to tell you what Square  is. But for now, Square’s dongle and Register are still rare sightings. And in app form, Square Wallet is still one of several payments apps like LevelUp  or Belly  or Passbook that its downloaders have tucked away in the “Pay/Deals” folder of their smartphone.
Directory is a searchable database that lists Square businesses by location and name. More than 200,000 businesses have signed up to display their locations and menus on the app and on the website, Square says.
