So after I got an email from Traveloka, I went straight to Osaka Station and looked for a place to exchange it. So, remember, REMEMBER, this ticket is only valid for Metro stations, not for JR or other train companies. After exchanging it at the Metro counter at Osaka Metro Station, the way to use it is to just insert it on the platform. Remember, insert it on the platform (not on the platform). It is valid for 2 days after use on the platform. The point is, whoops it up if you want to explore Greater Osaka using this. AWESOME👍👍
