More than 80 percent of the nation's regional banks are considering switching from magnetic cash cards to ones embedded with IC chips to make counterfeiting more difficult.

A Kyodo News survey shows that 14 of the 112 responding regional banks have suffered damage from counterfeit bank cards.

But the survey, conducted last week, found that 47 banks, or more than 40 percent, set no upper limit on the amount of money that can be withdrawn from an automated teller machine, making it difficult to protect deposits.
