A computerized identity card checking system has been introduced at 12 local blood collection centres and 19 medical clinics to prevent blood sellers from making illegal profits, Shanghai Morning Post reports.

The system was purchased from the public security bureau, according to officials of the Shanghai Blood Administration Office.

While the city encourages voluntary blood donation, it still imposes quotas on companies to guarantee a sufficient blood supply.

As some employees are unwilling to donate blood, some employers or staffers hire "professional" blood dealers or sellers to give blood in their place to fulfil the company's quota.

Many blood dealers and sellers use counterfeit ID cards when selling blood.
