下列影片介紹藏在衣褲鈕釦裡的RFID，真是如此則以後大家的隱私就不保了～

下列影片介紹藏在賣場監視系統加上RFID偵測(0'25")之後，消費者的一切都被監控了～

在電影「關鍵報告」中有一幕(2'05")，是主角一路走著看到周邊播出的都是針對他所做的廣告，這也是RFID引發的隱私問題～

下列影片介紹護照裡的RFID若被恐怖份子偵測到然後引爆炸彈攻擊(2'50")，然後介紹可阻隔RFID訊號的防護套～

It is a novel application of simple circuitry to prevent access to any information stored on the chip of a contactless RFID device. In its normal or “locked” state, the device’s antenna is detuned; effectively analogous to shorting the antenna. In this condition, it is impossible for a reader to access the chip and prevents the chip from transmitting any information; the card is completely disabled. Being completely disabled also prevents the chip from being detected and the card from being tracked. To use a card that incorporates ‘Dead Bolt’ technology, the user positions it near the desired reader, as they would with any such RFID enabled card, then applies and releases a gentle and intuitive pressure. Using time tested piezo technology, this pressure activates our circuitry which momentarily retunes the antenna, “unlocking” the card. Once the antenna is retuned, the reader can energize the antenna, access the chip and the chip can transmit its stored information. As highlighted, this is a momentary condition. Duration of reader access to the chip can be varied to the requirements of the device provider. For purposes of demonstration the card in our video is set at 200 milliseconds. At the end of the predetermined access period our circuitry automatically detunes the antenna, returning the device to its normal or “locked” condition and again, positively preventing access to the chip.
