Square

Square sells hardware, such as a point of sale (POS) system. It has analytics and sales reporting capabilities as well as the tracking of sales and inventory. Clients can use the POS to process their customers' payments that are made with credit or debit cards. The POS includes the Square register, customer display, a power adapter cable, and more. There is also a Square Terminal system that can also take payments and print receipts. Clients can buy smaller hardware that connects directly to their own smartphone or tablet and reads credit or debit cards. These devices are known as the "Magstripe" and "Contactless and Chip".

Square offers an online platform for creating e-commerce websites capable of selling products and services, order fulfilment, shipping, and accepting online payments. E-commerce websites made on the Square online store are charged 2.9% + 30c per transaction on the website. Each site is free to make and is not subject to monthly fees. Websites built through the Square online store do not require any coding experience.
