In the same vein of electronic business cards, the original NFC design was expanded. The antenna traces around the outside were copied and shrunk to place five concentric antennas around the card. Conceptually, this should allow the field shape to be defined better than waving a single LED. Similarly, more than five LEDs would give an even higher definition idea of how the field is shaped.
It turned out that the inner-most antenna traces picked up the least energy. This could be a matter of the shorter antenna traces or it could be the distance between the traces. In all the other antennas, there was a significant gap between all the traces.
