Google has a barcode on it's website instead of the words Google. I couldn't help but think that there's a good conspiracy in this.
It seems some in technology circles support RFID chips and maybe there getting the people that's coming to Google ready and familiar with the
barcode, hmmmmm.......
This is so funny,I went to 'google' something and came across Google with the 'barcode' in place as you mentioned,so I googled 'What is up with
the Barcode on Google'? www.google.com.au...
It seems that this got a bit of attention!
I don't think it is anything to worry about...
