TM touch type: With a production history of over 15 years, it has advantages such as durability, low failure rate, damage resistance, and long battery life. It has always been the mainstream product of global patrol malls, with the beauty metaphor of "all-weather universal patrol". The patrol stick and patrol point are designed with all metal raw materials, with a service life of more than 15 years, high temperature resistance, no fear of open flames, corrosion resistance, acid and alkali resistance, no electromagnetic interference, and resistance to damage, rain and snow. Shortcomings: Every time I read a card, I need to have a quiet contact with the patrol staff and patrol points. The need for normal use after over 1 million conflicts and wear between patrol sticks and patrol points!

RFID induction type: With the development of RFID technology, induction type patrols are gradually being carried out. Its biggest advantage is that it does not require touch card reading and close range sensing. Able to embed patrol points shallowly into the wall (limited to non-metallic materials, if installed on the surface of metal objects, it can only be pasted). Sealed and waterproof, resistant to falling after use. The disadvantage is that the patrol stick and patrol point cannot be completely metal enclosed, and the card reading head and patrol point of the patrol stick need to be made of plastic material. In terms of firmness and service life, compared to touch based patrol, it is somewhat inferior
