Hi Larry,
I haven't used Prizmo or Text Grabber for rounded labels, but I find that
another fantastic app and one I use almost more than Tap Tap See now is
Talking Goggles. It has a video mode which means it continuously recognizes
things as you move it and it will do short bits of OCR. I have used it very
successfully on cans or medication bottles.
As for QR codes, here is what Wikipedia says followed by the link to the
full Wikipedia article:
QR code (abbreviated from Quick Response Code) is the trademark for a type
of matrix barcode (or two-dimensional barcode) first designed for the
automotive industry in Japan. A barcode is an optically machine-readable
label that is attached to an item and that records information related to
that item.
The information encoded by a QR code may be made up of four standardized
types ("modes") of data (numeric, alphanumeric, byte / binary, Kanji) or,
through supported extensions, virtually any type of data.
The QR Code system has become popular outside the automotive industry due to
its fast readability and greater storage capacity compared to standard UPC
barcodes. Applications include product tracking, item identification, time
tracking, document management, general marketing, and much more.
A QR code consists of black modules (square dots) arranged in a square grid
on a white background, which can be read by an imaging device (such as a
camera) and processed using Reed-Solomon error correction until the image
can be appropriately interpreted; data is then extracted from patterns
present in both horizontal and vertical components of the image.

Subject: text grabber and prizmo
I was reading on the app store site and it seemed that the newest release of
prizmo was a step backward and got a very negative review. Now to a
question. Will either TextGrabber or Prizmo recognize text on rounded
objects like cans or bottles. Also, In looking at camfind, reference was
made to "qr codes". I know bar codes but what are qr codes? Again, thanks
for all the great info.
