From Venkatramanan Krishnamani:
You can activate up to three credit cards. You can personalize each credit card. The user can specify their credit limit, initial balance, and a personal alert level, which notifies the user when the Spending on the card approaches the alert amount level set by the use. This is especially useful and serves as a reminder to make a payment to the credit card. The interface also provides spending Limit Tracker, indicated by a blue bar which gives the user an idea of how the user is doing based on his/her "personal alert level". Always make sure you see the blue bar and you will build excellent credit faster than you can imagine. Easy inputs for both expenses and payments made to the credit card are provided. This allows the user to record the payments made back to the credit card as well.
