While similar in some ways to RFID—radio frequency identification—chips, there are key differences in Memory Spot technology in data transfer rates, storage and security.The chip can transfer data at 10 megabits per second, 10 times faster than Bluetooth wireless technology, comparable to Wi-Fi rates and far faster than RFID. Also, HP has managed to store up to 4 megabits in working prototypes of the chip, far more than an RFID chip can store.

The Memory Spot is about the size of a match head and is powered by inductive coupling. Data transfer requires a reader that touches or is within a millimeter of the spot.
