The machine induces an electrical circuit in the NFC device, which allows a short exchange of data to effect a transaction, such as deducting a fare from the stored value.

NFC设备内部发生电流感应，造成了影响交易的短时数据交换，比如从储蓄值中扣除某种费用。

But then there is another difficulty: making the components exactly the right size is even more crucial for a quantum-effect device than for a regular transistor.

To find out what effect a cooling device might have on athletic performance, Dr Grahn and Dr Heller recruited a colleague who was a recreational weightlifter.

It's also unclear why RIM bothered using fancy piezoelectric switches rather than simple mechanical ones, because they're not doing anything with the technology other than letting you click -- when you turn off the phone, the switches "harden" and prevent you from pressing the screen, but there's no option to keep that effect going when the device is on.
