PASMO check is a handy app that lets you check the PASMO balance without having to take out your smartphone. It can be used on any PASMO-enabled device such as a smartphone or a tablet. Just hold the tag back and the app will show you the current balance.

It is also useful when you want to know the current balance of a specific account, even if that account is on another device. This can be useful if you want to transfer money from one account to another, or if you want to set up a recurring payment for a certain amount every month.
