Square is a popular payment processing service that offers software and hardware solutions. Originally the company started with a small credit card reader that worked via headphone jack in 2009.
Square has built a highly successful business with easy to use software and hardware that appeals to a range of businesses from individual entrepreneurs up to larger businesses like retailers.
In 2015, Square launched its contactless and chip reader that brought Apple Pay support. While the company has updated its Square Stand offering for use with iPads over the years, it has also released a dedicated, integrated system called Square Register.
