How are companies using QR technology? Companies use QR codes in many ways. A couple of examples are putting QR codes on your business cards, so when they scan them it has all the business info on there. Sending QR codes to customers so they can be directed right to the business website. Also, they could use the QR codes for discounts on items, the customer can scan the QR and they’ll be able to get a discount on their item.

Is a QR Code an input or output device? A QR code in an input device.

What are the benefits? Is there a downside? Benefits of     QR codes are that they are easy to use, being able to interact with the business in a way. To me, it doesn’t seem like there’s any downside to using QR codes unless someone really doesn’t use technology much, but other than that it’s pretty beneficial.
