Review on AMEXCOS Proximity EM4100 Control Security by Daniel Mandal

Just returned seven orders. It is planned to use it as an access control to a vending machine for bulk purchases. Our original access control system failed in our first national customer demo. We order this detachment to step in and rush to the golden ring. It's impossible to express how hard our team tried to handle this product. It comes in such nice clean packaging, why make such a bad product? Waste of good PCB sealant. Why?! I don't understand these companies that spend time developing a product that doesn't even come with minimally useful programming or functional instructions. in the garbage can on the roof. ME with the EE consulting team. At full production, we would use a thousand units per month. These guys missed the money boat.
