You can begin using the service immediately following registration. When turning the card off, the little green button in the top right corner of the card image will turn to red. This means that all transactions (except recurring) will be declined. When ready to make a purchase, you can turn the card back on instantly.
In addition to the card on/off function, you can start selectively setting controls and alerts by channel (in-store, online, mobile, ATM, etc.). You can also set transaction spend limits, select geographic locations where the card can be used, set specific merchant categories, view recent transaction history, receive real-time alerts and much more.
