Connecting the entire home has been an ongoing trend here at CES, and Sony has introduced an interesting concept to acheive that goal. Xperia SmartTags are NFC chips that you can stick throughout your home and program with different actions and settings. When you enter the room and tap your phone to the SmartTags, your phone will automatically adjust to the profile you created. Pretty cool concept. They'll be released in Q2 for about $25-$40 for four tags and will be compatible with all NFC-capable Xperia devices -- take a gander below the break to see what Sony has to say about them.
