The mobile phone industry is improving and accelerating. More and more things you used alone in the past have been occupied by mobile devices or already used. Mobile phones and smartphones can be used for conversations and text messages to listen to music, watch videos, take photos and videos, and can also be used as notebooks or recorders, GPS navigators, maps, Internet access and games. Are key holders surprised? Based on key card and car lock technology, you can use this function to open the front door, hotel door, office, garage, and even your car through your smartphone. This technology is called Near Field Communication (NFC). Imagine that instead of using a key to open the door, you moved the phone near the lock to open it. The same applies to cars and any other door you can imagine.
Now, suppose you are working and your friend has come to your home. It is only a few hours from the end of the shift, and it doesn’t make sense for your friends to go elsewhere. What would it be? Does he or she have to sit at the front door? What if the weather is not good and it rains? Still winter, cold, snowy and uncomfortable? The mobile phone engine starts but with the help of technological advancement, you can control the situation. At the press of a button, the smart portable jammer device you connected will send a signal to your door and unlock it to allow your friends to enter. You can apply it to your car. In the hot summer, you can turn on the air conditioner, and in the cold winter, you can heat the engine and passenger compartment.
Although this amazing technology has many uses, there may be some dangers. Thieves, hackers and other fraudsters will eventually become more technical. They will use electronic devices to break into your house or steal your car. Therefore, you must be prepared. As mentioned at the beginning, wireless wifi is always more destructive to reliably defend against these villains. You will not let thieves do their dirty things, when you return home, you will use the remote control to turn them off at different frequencies. Therefore, you can be protected in the future and combine the advantages of new technologies with security measures.
