In this paper, 14 digits were adopted for encoding collection bins and ultra high frequency RFID was to identify the bins. The relationships of harvest information and production information, package information and harvest information were established by developing portable record-keeping system for vegetable harvest and upgrading vegetable production management system. Based on the identification and information recording, a solution was designed to improve traceability precision on the mode of specialized farmer cooperatives. The solution was applied in the traceability management of one specialized farmer cooperatives in Tianjin. The results showed that the solution could improve the traceability precision. Comparing with the existed traceability solution, the solution had obvious advantages of basic traceability unit, recall cost and check cost, but needed additional investment for equipments and staff.
