This app only supports Felica transit cards.
Do you want to check-in your event participants with their transit IC card (like Suica)? Do you want your employees to check-in quickly?
You can register your event participants / employees transit IC card with the application. Then, you will be able to scan the card to record a check-in.
You can also view the recorded check-in events by dates, or by scanning a transit IC card.
Notice: For important events, you should manually verify the participants identity by asking for an identity document. Its not safe to only rely on the scanned ID of the transit card.
