In the process of trying to accept modern credit card payments on a desktop computer.  Is additional POS software purchase required to use the EMV  Ready PIN Pad 

https://quickbooks.intuit.com/point-of-sale/hardware/

or is there similar hardware that can be used directly with https://merchantcenter.intuit.com/ 

?

Any way to accept chip cards/contactless payment that does not require a phone/tablet but can be USB plugged into a desktop computer?
