We've also got an iris scan which we had last year as well as facial recognition.

它还有去年就推出的虹膜扫描和脸部识别。

The checkpoints at each intersection with their metal detectors, ID checks and iris scans, the CCTV cameras which pervade the city and the riot police on every corner.

每个十字路口的检查站都有金属探测器、身份检查和虹膜扫描，遍布城市的闭路电视摄像机和每个角落的防暴警察。

Every month, aid organizations transfer money to individual blockchain accounts, and then that individual can go into a store, shop for the groceries and at the checkout they pay with the iris scan or with another authentication method.

每个月，援助组织会把钱转入个人的区块链账户，那个人就可以去商店，购买杂货，在结帐时，他们用虹膜扫瞄来付款，或用其它身份验证方式。
