In the hospitality industry, "Near Field Communications" (NFC) now has an
even more secure network that assists the utilization of total hotel security,
individual room monitoring for the HVAC system, more bedside controls for
lights, electronic drapes, monitoring who is at the door, fire and smoke
security, excessive electrical usage, all centrally monitored by management and
the individual guest, from network controlled smart devices that we all
carry.
Imagine a typical hotel (which already exists today). Your smart device is
already registered with the hotel or hotel chain. You walk into the front door
of the hotel and there are sensors by the entrance/exit. You press the hotel's
"app" that is on your mobile device, you have now checked into the hotel,
without going to the front desk. The hotel's system sends your smart device an
arrival confirmation along your new room number. When you reach your room, the
app opens the door using NFC. Look ma, no keys needed. The door security device
registers your arrival time along with the device's ID info. In the meantime,
the HVAC system now sets the temperature of your assigned room to the
temperature from your profile. Housekeeping and the concierge are notified.
