據美國食品安全新聞網消息，目前美國多家公司利用手機二維碼技術，構建食品安全可追溯系統，方便消費者了解產品的生產時間、產地等信息。
消費者利用智能手機掃描產品包裝上的二維碼，就可獲取食品的產地、農場的信息，甚至食品的召回信息。同時商家可以利用二維碼追溯系統，可了解消費者對產品的反饋情況，拉近與消費者的距離。
部分原文報道如下：
Imagine that you're in the produce section at the grocery store. You pick up a container of leafy greens with a QR （quick response） code on the label and you pull out your smart phone. The camera on the device instantly reads the code and tells you exactly where and how the greens were grown, when they were harvested, and who owns the farm. Your phone also recommends recipes and gives you the option of automatically adding the other ingredients you need to your digital shopping list.
You decide to buy the greens. You take them home and put them in the fridge. The next day, you get a text message alert: "The product you purchased has been recalled. Throw it away and click here for a full refund." You toss the greens and breathe a sigh of relief.
This is not the future of food traceability, this is what is possible today and what shoppers will increasingly be able to do with any item in the grocery store.
