We are positioning ourselves between pricey rfid chips and qr codes , ' says sascha voigt , printechnologics ' founder and chief executive .

printechnologics创始人兼首席执行长福格特（saschavoigt）说，我们将自己定位于昂贵的射频芯片和二维码之间。

Yet silver , unlike gold , also has industrial uses in electronics , solar energy , medical devices and increasingly popular radio-frequency identification , or rfid , tags .

但白银与黄金不同，白银在电子产品、太阳能、医疗设备和越来越流行的无线射频识别（rfid）和标签上还有工业用途。

The system , which uses radio waves to send information from an rfid tag to an information reader from a distance of several feet , can be found in a range of broader applications , as well , from animal identification to tracking library books .

这种使用无线电波从一张rfid卡上发送信息到几英尺远的信息解读器上的系统，应用已极为广泛，从动物鉴定到图书馆书籍搜索都可使用。

Consumers know that if it doesn 't come with the rfid tag , which looks like an extra price tag , then it isn 't the real thing .

消费者只要看到商品没有附加无线射频识别标签（看上去就像价格标签一样）就知道这是假货。
