radio-frequency

基本解释

Unlike previous ones, the e-passports contain biometric data embedded in a radio-frequency identification (RFID) chip, along with the usual mugshot and optical bar-code.
跟上一代不同，電子護照除了包含照片及光感條碼之外，還記有生物躰征數據，植在無線電頻率識別（RFID）芯片上。
They suggest that any alien civilisation worth its salt would alight not on the photons of the electromagnetic spectrum—whether optical or radio-frequency—to send messages to other solar systems.
他們指出，任何有頭腦的外星文明都不會發射電磁波譜中的光子——無論是可見光波段還是射頻波段——曏另一個太陽系傳送信息。
A far simpler kind of chip called a radio-frequency identification (RFID) tag, which sends a tiny quantity of data over a short range when activated, can already be manufactured for 4 cents apiece.
有一種更簡單的芯片叫做無線射頻識別（RFID）標簽，它在被激活之後可以在小範圍內發送很短的一段數據，現在，其造價衹要4美分一片。

Other anti-counterfeit efforts include the use of radio frequency identification tags.

The company has been selling a new kind of anticheat chip, embedded with radio-frequency identification technology.
