Hi Martin, I want to introduce RFID tags in a business that sells one type of a product only. The basic idea is very simple. Let me explain. The product is sold via a counter where it passes through, the RFID antenna and tags which will be placed on the counter and clear bags respectively and will be used to detect when the product has left the counter. What we want at the end of the day is to count the number of tags registered on the system and tally it with the physical cash and ensure it matches. So we wanted a user interface that can allow us to easily - Record the Counted tags that have passed - If a customer makes a return it will pass through the same counter and it must deduct it from the count. - An interface that is simple to use for anyone without any background i...
