Can qr code be read by any mobile camera?

Can I read any QRcode using mobile camera, if I implement the a program which will implement zxing library. Or is there something like, different specification for each code. Lets say I am implementing a program to create a QR code and he who needs to read this code needs to know my specifications, or his reading program has to know my specifications?

Yes

  1. Specification: There is no difference in specification for formats (now they are stable)
  2. Camera: Cameras without auto-focus cannot (or find it difficult to) scan a QR Code

Note:

  1. There is no official specification for this -- the QR code spec does not say anything about the contents. Everything I know about the commonly-used and de facto formats and conventions is summarized in this wiki: http://code.google.com/p/zxing/wiki/BarcodeContents

  2. Most cameras these days have autofocus
