The ‘state of the art’ traceability platform is integrated with the industrial park’s existing big data platform provided by Beijing Aokemei Tech & Service. Upstream information such as batch, picking dates and inspection can be associated with the unique codes, allowing all data to be stored in one central platform for full traceability. The project involves the application of unique, secure, and traceable QR codes to every pack of radishes. In addition, there is a four-digit hidden pin code for authentication.
