South Korea's credit card spending grew at a slower pace in February than a month earlier due to a one-time effect, data showed on Tuesday. Purchases made with credit cards reached 41.48 trillion won (US$38.52 billion) in February, growing 2.5 percent from a year earlier, according to the data compiled by the Credit Finance Association. The February figure is compared with 46.9 trillion won worth of credit card spending a month earlier and also marks a slowdown from a 9-percent on-year gain in January.
