How do I register for the Guardian alerts service?
Signing up is easy. In fact, you can sign up in just a few steps at the Guardian website
Can I request the criteria for alert messages be customized for me? For example, can I increase or decrease the amount of the transaction before an alert is generated?
No. Bank Midwest has determined the criteria for the types of transactions that will generate a Guardian Alerts text message. These rules apply to all debit card customers and cannot be customized for individual cardholders.
As a cardholder, is it safe to receive text alerts regarding my transactions?
Yes. Text alerts do not contain detailed cardholder information. Only the last 4-digits of your card number appear in any text message.
What happens if I don’t reply to a text message?
Nothing. 12 hours after the transaction, the alert will expire and it is assumed that the transaction is valid.
What happens if I reply to the text believing that the transaction is fraudulent?
Your debit card will automatically be deactivated preventing your card from future use. Once your card is deactivated, this action cannot be reversed. A new card will automatically be ordered for you. If you do not wish to receive a replacement debit card, contact Bank Midwest within one business day.
I’ve received calls from the Fraud Center on behalf of Bank Midwest in the past regarding suspicious card activity. Now, will I receive both text alerts and calls?
Yes, because these are two different security solutions. It’s possible you could receive a text message and a call. The text alerts will automatically be generated for three specific types of transactions – whether or not there’s any sense of suspicious activity:
- Authorization amounts greater than $400
- Transactions where the card is not present or the card number is manually keyed
- International transactions
Fraud Center staff will know when you’ve received a text alert on a transaction. If you reply to a text alert, analysts will work the fraud case, deactivate the debit card, and notify Bank Midwest. Fraud Center analysts will place phone calls to cardholders regarding suspicious card activity using a different set of guidelines.
What if I received a text alert for a transaction but I’m not sure whether it is fraudulent or not?
If you have any questions about a transaction and whether it was authorized or fraudulent, please review your account details online. Or, you can call your local Bank Midwest branch or Customer Support at 888.902.5662. You have 12 hours from the time of the transaction to investigate it. If no response is received, it’s assumed that the transaction is valid.
Will I recognize that the text is from Bank Midwest?
The text message will begin with “BkMid Guardian Alert … ”. BkMid is a shortened abbreviation for Bank Midwest.
Does it matter what kind of mobile device or carrier I have?
The cell phone or mobile device must have the ability to send and receive text messages and the use of “short codes” must not be blocked. Short codes are special telephone numbers, often five digits long, which are used to send text messages from mobile phones.
You are responsible for any text messaging fees from your carrier. Message and data rates may apply. There are no additional fees from Bank Midwest.
