How to Scan a code from a snail mail or magazine

[GrahamZ]

I don't know what the codes are called (they aren't the same as bar codes, but the same principle).  I can't find any documentation on how to do this with my S3.  I got some mail from a company I very frequently do business with that has one of those codes, and it says I should scan it with my 'smart phone' to download their free app.  Someone told me that all I need to do is take a picture of it, but that doesn't work, and I can't decipher the various icons (my eye sight is pretty poor in any case so it's sometimes difficult to distinguish between one icon and another, in any case or figure out what they are supposed to represent).  I've even tried cropping the picture down to just that code, but that doesn't work either.

BTW, I'm not the only one having this problem -- I asked a friend and she told me that I should tell her when I figure it out because she's been unable to make heads or tales from this as well.  If it's possible, it ought to be in the manual.

You have to install a bar code scanner from the Play Store. Look for one that can scan multiple bar code types including the QR code (the square shaped ones).

Nevermind -- I found an app for it 8-).
