The chip has a 10 megabits-per-second data transfer rate—10 times faster than Bluetooth wireless technology and comparable to Wi-Fi speeds— with a storage capacity ranging from 256 kilobits to 4 megabits in working prototypes. It could store a very short video clip, several images or dozens of pages of text. Future versions could have larger capacities.

The chip incorporates a built-in antenna and is self-contained, with no need for a battery or external electronics. It receives power through inductive coupling from a special read-write device, which can then extract content from the memory on the chip. Inductive coupling is the transfer of energy from one circuit component to another through a shared electromagnetic field. A change in current flow through one device induces current flow in the other device.
