On March 18th, IC card ticket, PASMO which can be used at most trains; JR, private railroads, municipal trains, subway, and buses in Tokyo and seven neighboring prefectures started.
PASMO inserts IC chip, and you can charge money from 1,000 yen to 20,000 yen at ticket machine. The fare is deducted from automatically when you hold PASMO over the automatic ticket gate for trains or buses. You can use PASMO even in shops in the station yard as electronic money, such as eat Soba and buying drinks at vending machine by hold PASMO up over a reader.
The new transfer card system started with 27 railway companies and 32 buss companies. After April, the use of PASMO can be expanded into 30 railway companies and 76 buss companies.
In fact, there, Suica which has almost the same function with PASMO by JR already exist. So, you can use mutually both PASMO and Suica now. Besides, you can change your usual magnetic commuter card into PASMO.
I already have one PASMO for my commutation ticket. It is nice for me when I take it from my bag. I just hold card case PASMO inside over the reader, and I don’t need to stop in front of the reader to take one card. That’s what is good as IC card.
