What it does
Square Reader SDK lets you take in-person payments with Square hardware
Build a custom Point of Sale, a self-service kiosk, and accept payments with Square hardware using Square APIs and SDKs.
Whether you’re building a custom point of sale (POS) or a self-service kiosk, you can now connect to Square Stand, Square Readers, and Square Terminal by integrating with our APIs and SDKs for in-person payments. Let Square manage the complexities of payment processing, including security and compliance, so you can focus on building a world-class product. Build with Square Terminal API to give your sellers access to the sleek Square Terminal device for all-in-one credit card processing and printed receipts. Or, build with Square Reader SDK to give sellers an option between two Square Readers and Square Stand for in-person payments.

Talanoa▲345Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself.
