If you want to suspend using ZA Card, you can use the 'Lock Card' function:
1. Tap the「ZA Card」icon in the menu bar
2. Tap the「Setting」icon in the top right of the screen
3. Select「Lock card」
Once you have locked your ZA Card, all card purchases and ATM withdrawal
will be automatically declined (excluding the transaction adjustments initiated by bank on a previous purchase, if there is any). After card activation, ZA card can only be cancelled together with ZA Bank account closure.
