Square provides products like the Square Reader, Stand, Wallet, and Market that allow merchants to accept credit card payments on mobile devices. The company has raised funding in four rounds and was valued at $5 billion in January, and is expected to be acquired soon. Square was created by Jack Dorsey with the goal of giving everyone access to card terminals, and has support from major credit card companies. Its Square Cash product allows person-to-person payments like Venmo without needing a terminal.
