NFCWIFI remote access control

Preface: Going back to the dormitory after class every day is quite tiring. When you get to the door, you have to search for the key, insert the key, and twist the key again. This is so inhumane and wastes so much time and energy. Isn’t it okay to open the door? Is it a sense of ceremony? Can't you hear a warm female voice like "Oh, Master xx, welcome home" after opening the door? ---------These are all nonsense, mainly because people are too lazy and want to be more convenient~. You can have rituals and conveniences at a cost of about 50 yuan.
