No, the ones the OP are refering to are /not/ bar codes. They are QR
codes.


First, note his description: "square boxes that are filled with a
bunch of dots and three of the corners have small boxes in them"


Now do a Google image search on "QR codes" to see what the OP is
asking about.


They ARE UPC codes, but not bar codes per se. They're actually called
2D or Matrix Codes. QR is a marketing term. They're used because they
hold LOTs more data than the 13 digits a "bar code" can hold. The UPC
organization is involved in their evolution. In 2014, they'll start
replacing "bar codes".

The bar code/matrix code technology is old. very old. It's the ability
of a smartphoen to read it that is recent.- Hide quoted text -

I beg to differ. I'll agree that they are not bar codes...that's
obvious.

However, I don't agree that QR codes are UPC codes.

If you DAGS for UPC codes, you'd be hard pressed to find a site that
doesn't define them as "bar code symbology". Logic holds that if
UPC's are created using bar code technology and QR codes are not bar
codes (which you ahve stated) then QR codes can not be UPC's.

Besides, UPC code are used to identify a specific product or item,
using a code that can be understood universally, thus the name.

QR codes rarely specific to single item. They are used mainly to
provide information about a brand, a group, a website, etc.

Do a Google Image search on "qr codes" and scan some of the images
with a smart phone, then tell me why you feel that QR codes are UPC
codes.
