Get A Digital Door Lock
It looks like a phone but it is not one. It looks like you can make calls from it but actually you can't. This is 21.5 mm thick digital door lock and it comes with a touch sensor. Korean company Seoul Commtech has launched this digital door lock called EZON (model: SHS-1110) in Korea. It is designed with aluminum-alloy construction and black colored tempered glass. Suggested price is 170,000 KRW and that's around $180. Sure seems to be a great thing in the name of security and it even looks good.
