The tra e in the period of produ tion is a bottle ne k in thewhole tra eability system be ause of farm produ ts long produ ing period and distr ibuted produ ing areas. A novel tra em ethod was proposed, in wh i h produ ing areas, produ t varieties, produ tion date and attestation types are en oded and all related inform ation is stored in tags. The tra e information in the period of produ tion ould be re orded and read outw ithout networks and database.
