We started with a simple idea—that everyone should be able to accept credit cards—and we’ve been rethinking buying and selling ever since.

For sellers, we’re creating one cohesive service to run your entire business, from a register in your pocket to analytics on your laptop. For buyers, we’re making it faster to order from the businesses you love and more fun to pay your friends back.

Buying and selling sound like simple things—and they should be. Somewhere along the way, they got complicated. We’re working hard to make commerce easy for everyone.

Our hardware team builds the tangible connection to all that is Square. With the Square Card Reader and the introduction of Square Stand, our family of devices is growing - and this is only the beginning. As we introduce more and more of our products to the world, our hardware footprint expands.

Our hardware engineers are responsible for designing and developing world class hardware products. They understand the subtleties of user interaction, robust communication interfaces, and smart product design.
