The system had the potential to include real-time risk analysis that could trigger the request of a PIN for a transaction that falls outside of normal parameters.
Studies on people have left more questions than answers, and laboratory experiments have failed to pin down a plausible mechanism whereby weak magnetic fields could trigger the disease.
Other advantages include a lighter magnesium alloy body, an NX power pin-enabled hot shoe for adding an external mic or flash, and a new micro-USB trigger cable.
