The best thing about this product is that it can be used to scan any device without having previous knowledge of its type or model number (Possible with other products).It also provides excellent support via live chat feature available 24/7 for customers' assistance in solving their issues related to security devices such as RFID readers etc., It will definitely help you if your organization has many employees who often need access control solutions at different places within an office building like retail stores, banks offices ect..The worst part I've found so far are some delays when using mobile applications due lack luster internet speed but they have good customer service team ready always willing to assist us anytime we call them from our side! So no dislike yet just waiting patiently until my experience meets more positive results than negative ones :) As mentioned before there might sometimes appear small delay while scanning certain items through android application especially large files over 5mb-10 mb may take longer time compared to smaller size file.
