TOKYO - Railway firms including East Japan Railway Co. and West Japan Railway Co. experienced a technical glitch with their ticketing system Monday morning that temporarily prevented credit card purchases, their ticketing system management company said.

Cash purchases and Central Japan Railway Co.'s "Smart EX" online shinkansen reservation service were unaffected, according to Railway Information Systems Co.

The glitch occurred around 4 a.m. when ticketing machines and counters opened, the company said. A problem was found in the database of servers responsible for processing credit card transactions and was resolved around 8:40 a.m., Railway Information Systems said.
