HÀ NỘI — Since early 2018, Hà Nội’s consumers have been able to scan quick response (QR) codes to trace the origins of agricultural products sold at supermarkets and convenience store, however, the impact of this change has been limited because producers find the system difficult to apply and consumers do not fully trust the codes' authenticity.

By scanning the codes on products' packaging, customers can learn where the fruits and vegetables are grown, who owns the farm and the names of the producers and distributors.

Hòa Bình Co-operative in Hà Đông District was one of the first co-operatives to use QR codes to identify their fruits and vegetables. But after just three months, the group stopped using the technology.

Trịnh Văn Vĩnh, the co-operative's director, told Kinh Tế & Đô Thị (Economic and Urban Affairs) newspaper that the technology requires farmers to keep track of information about their crops and cultivation and then enter it into the software system. Maintaining accurate information with the QR codes takes three to four times the usual efforts than just putting a normal stamp on the packaging to indicate a product's origins.

“After a short trial time, we realised that customers do not really care much about the technology," he said. "Only one to two out of 10 customers scan the codes so we decided to stop applying it."

Nguyễn Tú Linh, a customer of PT Mart in the city's Hà Đông District, told the newspaper that it takes time to get out her smartphone and scan the codes.

“Each product has many different stamps and codes with various shapes and sizes," she said. "I can’t distinguish which one is the most accurate."

Trần Thu Hồng, a customer in Long Biên District, expressed doubts over the authenticity of the information displayed after scanning the codes. She said the information comes only from producers without the verification or supervision of any agency, so it could be one-sided.

Nearly two years after introducing the codes, 81 per cent of the city's fruit stores use QR code. The city’s Department of Agriculture and Rural Development issued QR codes for 236 enterprises and more than 4,000 products.

According to the city’s plan, the application of QR codes will be expanded by the end of this year to trace the origins of other agricultural products, production facilities, farms, slaughterhouses, large-scale processing establishments, supermarkets, wholesale markets and market management boards.

In 2020, all production chains in the city will use the codes to trace product origins and provide transparency for consumers. 

Under the plan, the rate of products with traceable origins through the codes from small-scale production and businesses will increase by 30-50 per cent.

To reach these targets, however, there are tonnes of work ahead for Hà Nội City.

Nguyễn Thị Thu Hằng, deputy head of city’s Agricultural-forestry-fishery Product Management Division, said the adoption of the technology remained slow and instructions on how to begin using the codes lacked details.

Most traceability efforts are conducted manually, requiring a lot of workers and raising doubt over the authenticity of the data, according to the official.

Farmers are not used to keeping origin records for produce, making it difficult to manage and supervise food quality.

Tạ Văn Tường, deputy director of the city's Department of Agriculture and Rural Development, proposed the agriculture ministry and Ministry of Science and Technology issue a full set of national standards on origin traceability for food.

In the future, QR codes will be mandatory for domestically produced goods. — VNS
