Square
All-in-one POS and card reader that turns any device into a till.
What it is
About Square
Square is a point-of-sale and payments platform that lets independent shops, market stalls, and small chains take card and contactless payments, ring up sales, and track inventory from a phone, tablet, or dedicated terminal. Its appeal is the near-zero setup cost — a small reader and a free app — which made card acceptance viable for tiny retailers and pop-ups that banks would not previously serve.
