Luckily for Rizwan, my team and I, working in partnership with the largest pharmaceutical company in Africa, have placed unique codes -- think of them like one-time passwords -- on each pack of the best-selling heart medicine in Egypt.

里兹万很幸运，因为我和我的团队和非洲最大的制药公司联合，在埃及每一包卖得最好的心脏药上面加上了独特的编码，可以把这些编码想象成一次性密码。
