Scan this for a message!
I have had my Nokia N95 8GB phone for a while now and never really worked out what the BarCode reader appication was for. I had tried to scan various barcodes but to no avail. Then I tried scanning one of the square stlye bar codes like on the left of this post, they are called datamatrix barcodes BTW, give it a go and see if you can decypher the message I have put in it.
Anyway, if you want to make your own datamatrix barcode visit the Nokia Mobile Codes website and give it a go. Not exaclty exciting but can easily was another 5 minutes of your life.
