IB CardControl app for iPhone and iPad

CardControl allows you to block and unblock your card with the click of a button. When the card is "on" transactions are allowed. When “off,” purchases or withdrawals are restricted.
CardControl protects your card by sending transaction alerts and enabling you to define when, where and how your cards are used. Set your preferences to monitor and manage your cards.
Alerts Enable Safe, Secure Card Usage
Real-time alerts for PIN and signature transactions keep you informed of your card usage to quickly detect unauthorized or fraudulent activity.
Location-Based Controls and Alerts
Restrict transactions to merchants near your location (using your phone’s GPS) or by region using city, state, country or zip code on an interactive map.
Usage Controls and Alerts
Set spending limits to decline transactions above your thresholds. Monitor activity by category such as gas stations and restaurants, and by type: in-store purchases, e-commerce transactions and ATM transactions.
