Am I able to view my deposit history within Mobile Deposit?

The deposit history can be viewed within Mobile Deposit for thirty (30) days after submission. History prior to that will be available through Online Banking.

When can Mobile Deposits be submitted to St. Mary's Credit Union?

You can submit Mobile Deposits 24 hours a day, 7 days a week including weekends and holidays.

When will my Mobile Deposits be posted into my account?

Mobile Deposits are typically processed like traditional paper deposits, and will be posted on the current or next business day depending on when they are received. In some cases, the window for processing Mobile Deposits may be extended beyond the hours for traditional paper deposits. Please refer to our Funds Availability Policy to determine when your deposit will be available for use.

What should I do with the original paper checks after the Mobile Deposits are made?

We recommend that you store original paper checks in a secure location for 60 days. This will allow you to keep track of which checks you have deposited with us and which still need to be deposited. Plus, the software is designed to compare each check to all previous checks that you have deposited. If a possible duplicate item is found, St. Mary's Credit Union will be alerted and all duplicates will be closely analyzed and addressed.

How do I know if the picture quality is acceptable?

Picture quality is required to meet certain specifications, including:

  • Checks should be written in blue or black ink
  • Handwriting must be legible
  • The MICR line must appear fully intact
  • Checks must be made payable to the member in ownership of the receiving account
  • Checks must be signed by the payor
  • Checks must be properly endorsed by the member
  • Checks must be properly dated
  • The numeric dollar amount must match the written dollar amount

If the check picture does not meet any of these specifications, you will be alerted.
