※ 다음 글을 읽고 물음에 답하시오. [문 6 ～ 문 7] _______________ When it comes to getting through the airport, travelers have found it's one or the other. Now biometrics may offer the solution to getting both at the same time. Passengers flying with Cathay Pacific and Emirates from London's Heathrow are being invited to take part in a trial of 'My Sense', the latest in biometric recognition systems. The security of a country's borders is one reason why this new technology is being introduced. Another reason is to help speed frequent travelers through passport control. In the future, these frustrated travelers will be able to speed past the queues with a touch of their fingers. If successful, this pilot scheme will be expanded, eventually including all European nationals flying out of Heathrow's terminal 3. All this technology is still very much in its infancy. It is, however, clear that in the years ahead the ticket for getting into most countries will be your fingerprint and your eye. That's the passport to the future. 문맥 상 밑줄 친 부분에 가장 적절한 것은?
