RF Energy Saver Socket

It works with RF-Mifare port cards. It is activated by reading the information inside the card with radio frequency. It doesn't matter which direction the card is inserted into the slot, it works in any direction. However, it does not even work with other RF-Mifare smart cards of the same type (Public transportation, bank, petrol, store, university ID, etc.), it only works with hotel lock cards. Thus, the energy saver system achieves its purpose. It works with 5V, it is safe. It has LED lighting to be noticed in the dark. It can be applied to the desired switch-socket series.
