Company Description

Square builds common business tools in unconventional ways so more people can start, run, and grow their businesses. When Square started, it was difficult and expensive (or just plain impossible) for some businesses to take credit cards. Square made credit card payments possible for all by turning a mobile phone into a credit card reader. Since then Square has been building an entire business toolkit of both hardware and software products including Square Capital, Square Terminal, Square Payroll, and more. We’re working to find new and better ways to help businesses succeed on their own terms—and we’re looking for people like you to help shape tomorrow at Square.

We started with a simple and elegant Reader that turns any phone or tablet into a mobile point of sale - and we continue to lead this category with advances in chip card and NFC technology. Next, we introduced the Square Stand, the best way to turn your iPad into a countertop point of sale.  We’ve expanded our HW portfolio with two new Android-based solutions: Square Register, the first fully integrated point of sale that enables people to start selling right out of the box, and Square Terminal, a portable point of sale that enables sellers to do business anywhere.
