I was recently asked to provide some information on identicons, a good excuse to restart blogging.

This post, more like notes actually, compares Identicon to QR code which may seem similar visually but are not.

WARNING: I think in random fragments, brief moments of coherency, so my posts will be the same.

Machine vs People

• QR codes are read by machines.

• Identicons are read by people.

Content

• QR codes are containers of information.

• Identicons are shadows of information they are associated with. 

Usage

• QR codes are used to transfer information from real life (RL) objects to computers using only optical means.

• Identicons are used to distinguish individuals or groups of information.
