The National Police Agency said Thursday it will develop a data-sharing system aimed at curbing the surge in crimes involving counterfeit credit cards, which caused losses exceeding 9 billion yen last year.

The new system, which will analyze fake cards seized nationwide, will help investigators work out the characteristics of forgery devices and crack down on counterfeiting rings, NPA officials said.

The NPA has applied for some 548 million yen in the supplementary budget for this fiscal year to develop a system for analyzing data on fake credit cards and to equip each prefectural police force with terminals to access the system.
