One approach, for example, would be to include on packaging a “scratch code” that includes a phone number for consumers to call in order to check that the batch number matches an authentic product. But, while this approach would certainly help to catch counterfeits, it would miss the substandard or degraded products made by legitimate firms, which are tested only by the consumer – and often at great cost in terms of health risks.
检测伪劣产品所需要的技术专家和设备通常超过了发展中国家的负担能力。但也有低成本替代方案。比如，一种方法是在嵌入“防伪码”，消费者可以根据码上的电话号码打电话验证产品批号和正品相同。但是，尽管这一方法必然有助于抓获伪劣产品，但合法企业生产的劣质或减料产品会成为漏网之鱼，消费者只有在使用后才能知道产品质量低下，通常这意味着极高的健康风险。
