Would my business or home benefit from NFC door entry system? All business premises and homes need to feel secure. A NFC (Near Field Communication) door entry system would benefit most business or homes that have multiple users. With NFC door Entry there will be one centralised control system, which in many cases is centralised over the internet in a cloud based system. The authorised user will then be able to enable or disable card keys or fobs to give to employees, family members or home helps for instance. The card or fob is then placed near a receiver panel that will allow the door to be opened. These systems work extremely well in settings such as hospitals, factories, businesses holding secure documentation, and business with valuable stock or equipment. Care homes and hotel are two areas where NFC door entry systems are also used to keep residence safe and hotels free from non paying guests.
