RFID Detects Food Safety With Innovation from MIT Media Lab Research

By Claire Swedberg

Companies are preparing to test the system to enable the detection of contaminants in food, such as melamine in baby food or methanol in liquor, with off-the-shelf UHF tags and a modified RFID reader.

Researchers at the MIT Media Lab have developed a solution using passive UHF RFID technology to detect potentially poisonous contaminants in containerized products, such as baby food and liquor. The system, known as RFIQ, employs basic UHF RFID tags, a modified off-the-shelf RFID reader and machine-learning software to interpret the RF response the reader receives from each tag. According to the researchers, the solution will be tested in real-world ...
