Keyless Entry and Smart Locks
The idea of smart locks has been out for a while, but at the end of the day, people still end up carrying either RFID or just use the lock itself. We pretty much carry our phone all the time now, and by the time we are at the door we are automatically connected to our own WiFi network. By using Serial to Ethernet (S2E), we can actually implement a true keyless experience, using our phone as the key and S2E to unlock the deadbolts.
