FAQs
What are some of the benefits of mobile check deposit?
Convenience
Being able to deposit a check using your mobile phone is incredibly convenient. You can deposit checks anywhere and at any time, so long as you have access to your phone and an internet connection. This increases the flexibility of where and when you get work done, all while reducing the need for additional trips to the bank.Avoid Waiting in Line
In addition to being more flexible, depositing a check using your mobile phone is much faster than going to the bank. It can be as simple as snapping a photo of your review and uploading it via the app. This process doesn't require you to wait long periods or go through extensive security protocols to access your bank account. This makes it much more suitable for busy individuals who don't have much free time to wait around at the bank.Security
Security will always be a central concern when it comes to mobile banking, and Arsenal Credit Union has you covered! We use industry-standard encryption protocols to protect your account information and prevent unauthorized users from accessing it. The ability to deposit checks using your mobile phone is a significant convenience and can save you time and money in the long run. Make the most of your free time and manage your money conveniently with Arsenal Credit Union—get the app today!
How long does it take for funds to become available when I use mobile check deposit?
It takes roughly one to two business hours at max. Funds may be held on certain deposits. If you make a deposit at night or on the weekend, the funds will usually appear in your account the morning of the next business day (usually before 9:00 a.m.).
What requirements does mobile check deposit have?
You must have an open and active savings account, mobile banking and be a member in good standing. Your account must also have a positive balance for the past 90 days.
Do I endorse checks normally?
You will endorse your checks with a signature. In addition, on the back of your check, you will have to write FOR E-DEPOSIT ONLY AT ACU.
How much can I deposit with mobile check deposit?
The amount a user can deposit is based on tiers. Members enter a new tier based on successful transactions. Tier one starts at a $1,500 single-day deposit, while tier three starts at $10,000. Ask us for more information.
Can I give others access to mobile banking so they can deposit checks on my behalf?
No. Some fraudulent loan companies will claim that they need your username/password to access Mobile Check Deposit to place funds in your account using a bogus check. When Arsenal receives these “checks,” we reject the deposits because they look suspicious. We also have to close your compromised account and have you come in to open a new one for safety reasons.

An alert is a text notification sent to your cell phone when a transaction takes place with a specific card. A control/restriction limits the use of the card based on the preferences or filters you defined.
Will the card alerts and controls previously set up on Arsenal’s website still work?
No, if you previously set up alerts for your card on our website, you will need to set up new alerts in the app.
How quickly are the alerts, controls and lock/unlock features activated?
Within moments after you hit “submit,” the locks, controls and alerts are activated.
If I’ve enabled alerts, how will I receive my notifications?
Alerts, when enabled, will be sent as SMS text messages to the phone number that is in on your profile. If you enable alerts, please make sure a valid phone number that can receive text messages has been added to your profile. You may receive your alerts at the email address that is on your profile if the service that delivers text messages is temporarily unavailable.
I’m trying to report my card as lost or stolen and I’m getting a message “It looks like you are trying to update your address.” Why can’t I complete my lost/stolen report in this app?
You are getting this message because you reported that the address we have on file is not correct. We do not want to process the report and then send your replacement card to the wrong address, so we need to update your address first. Please call us at 314.962.6363, Option 6, for assistance.
