Early this year, the state authorities concerned issued the information that China's first national standard on eggs---national standard of nuisance free eggs will come out this year. In due course, the tested qualified eggs will be attached with an "identity card", i.e. spraying printing ink on egg to indicate place of origin, production date, etc. The originally narrow egg code machine market is widened suddenly for code equipment manufacturers. National Business Daily: known from Shanghai Huabei Photoelectric Technology Development Co., Ltd., its egg code machines see booming market from the next half of the year.

According to the coming standard, eggs must be attached with the "identity card" when they are put into the market, i.e. they must be sprayed edible grade red ink to indicate "organic egg" and "nuisance free egg", their producer, trademark, lot number and other data, while these must be done by special purpose code machine. Mr. Yao Jin, the general manager of Huabei Marketing Department told: "such requirement has been given to egg suppliers in some supermarkets in Beijing and Shanghai". To poultry cultivation farms, egg code machine has become the necessary equipment for daily operation, and hereby the code machine market is promising.
