Like RFIDs, Memory Spot chips store data and have a built-in radio transmitter but the similarities end there.
RFIDs store a very small amount of data – enough to identify and describe an object but not nearly enough for, say, a photograph. And they are able to transmit up to 15 feet, which makes them ideal for inventory control.
Memory Spots, on the other hand, can transmit only about 1 millimeter so the reader has to come into almost touching distance. That limits the applications but increases privacy and security because you don't have to worry about someone reading your data from across the room.
The Memory Spot has a fully integrated antenna that's part of the same silicon as the chip itself while RFIDs have attached antennas. Some RFIDs need a power source but the memory spot will never need any type of battery.
The power necessary to transfer data from the spot to the device is embedded into the reader. When the reader gets within a millimeter of the chip, it provides the necessary energy to transfer the data.
