Many years ago, scientists predicted the coming of non-cash age. Since the popularity of credit card, the public was so excited about the improvement. But now, people have gone much further, they can pay online with Alipay. When the public is crazy about the non-cash age, the technology has pushed people to come the time of scanning face.

When the public first heard about scanning their faces in the shop, then they could buy the products they wanted and the machine would recognize their faces, they thought it was impossible. But when the shop was put in the market, they realized it did work. Scanning face could save much time. They don’t need to waste much time to stand in line. How convenient it is.

But people worry about the reliability of this new technology. What if a person looks much like another, or how the machine can recognize the twins. The machine can identify the person by the facial features according to different person, but for the twins, it is hard to tell. Though this technology is not perfect, it is still the future way to pay.

許多年前，科學(xué)家預(yù)測了無現(xiàn)金時(shí)代的來臨。因?yàn)樾庞每ǖ钠占?，公眾對于這樣的進(jìn)步感到很興奮。但是現(xiàn)在，人們走得更遠(yuǎn)了，可以用支付寶在線付款。當(dāng)公眾還在對無現(xiàn)金時(shí)代興奮時(shí)，科技可以通過掃描面臉部讓人們走得更遠(yuǎn)。

當(dāng)人們第一次聽說在商店掃描他們的臉，就可以買他們想要的產(chǎn)品，因?yàn)闄C(jī)器會(huì)認(rèn)出他們的臉，大家都認(rèn)為這是不可能的。但是當(dāng)這樣的商店投放到市場的時(shí)候，他們意識到這確實(shí)可行。掃描面部可以節(jié)省很多時(shí)間，人們不需要浪費(fèi)太多的時(shí)間去排隊(duì)，真的非常方便。

但人們擔(dān)心這種新技術(shù)的可靠性。如果一個(gè)人跟另外一個(gè)人長得很像，或者說機(jī)器怎么分辨雙胞胎？雖然機(jī)器可以根據(jù)不同的人識別面部特征，但對于雙胞胎，卻是很難分辨。雖然這個(gè)技術(shù)還不完美，但是仍是未來的支付方式。
