16 3. Problems and Concerns 1. Quality Improvements There were Many troubles 1. Mega Bank system troubles Performance trouble, when huge number of transactions came 16

17 3. Problems and Concerns 1. Quality Improvements There were Many troubles 2. Railway Ticket gate system trouble Programming error Ticket gate glitch hits over 600 Tokyo rail stations. TOKYO, Oct. 12 Kyodo Around 4,400 automated ticket gates at 662 railway and subway stations in the Tokyo area failed to operate properly early Friday morning when they were turned on for the first train runs of the day, prompting operators to give passengers free access at almost all stations by around 11 a.m. to avoid rush hour confusion, the operators said, adding that train runs had not been disrupted. The operators said the extensive malfunction is suspected of having been caused by a glitch in the programming that links gates and computer servers which handle the data for IC fare cards -- Suica for JR East passengers and Pasmo for other metropolitan subway and rail operators. All the affected gates were built by Nippon Signal Co. 17
