According to an FCC filing, the folks at Keurig (they basically make a single serving coffee machine) could be adding RFID tags to their pods in order to allow the machine to sense the type of coffee being placed into the device. This would, in turn, allow the machine to change temperature, milk type, and whatever else the coffee requires.
It’s all very pie-in-the-sky right now with little information as to how the RFID tags will be used. However, it is an interesting move in the SSC world. For example, employees could get certain coffee types out of the machine with an RFID tag or the pods themselves could communicate with certain machines. You could also automate the pod process, creating an all-knowing coffee robot. It could happen.
