We can read METRC RFID tags for states in which that is applicable. Otherwise, we can source affordable RFID tags for you. There is a variety of choices for RFID sensors and readers. We like to evaluate the equipment needs on a case-by-case basis with each client to help identifiy the best and most cost effective choice specific to their facility. Other examples of sensors are those used to monitor temperature, humidity, etc. We have an extensive list of hardware solutions on the market to choose from. We'd love to discuss this in more detail so contact us and we can set up a meeting!
