To use remote deposit, endorse the back of your check with your signature and the words “For Mobile Deposit Only,” open your bank’s mobile app, photograph the front and back of the check, type in the amount, and submit. That covers the mechanics. What matters more is what happens after you tap submit: which checks your bank will actually accept, how long before you can spend the money, and why seeing a deposit in your balance is not the same as the check having cleared.
Remote deposit is legal because of the Check Clearing for the 21st Century Act, which made digital images of checks legally equivalent to the paper originals.1Office of the Law Revision Counsel. 12 USC 5003 – General Provisions Governing Substitute Checks The law didn’t require banks to offer image deposits; it just made them valid. Each bank sets its own rules on top of that: which checks it accepts, how much you can deposit, and how long the money is held.
Endorse the Check the Right Way
Endorsement trips up more mobile deposits than blurry photos do. Sign the back and write “For Mobile Deposit Only” along with your bank’s name. Some apps reject the deposit outright if that language is missing.
The reason banks insist on this restrictive endorsement is legal, not cosmetic. Under Regulation CC, a bank that accepts a mobile deposit must indemnify another bank if the same paper check later gets deposited elsewhere and paid a second time. But if the paper carries a “For Mobile Deposit Only” endorsement, the second bank cannot make an indemnity claim because it accepted a check that was plainly marked as already deposited.2eCFR. 12 CFR 229.34 – Warranties and Indemnities Your bank requires the endorsement to protect itself, and by extension you, from a double-payment claim.
Photographing and Submitting the Check
You need a smartphone or tablet with a working camera, an internet connection, and your bank’s app installed and logged in. Place the endorsed check on a flat, dark surface with all four corners visible. Uniform lighting matters more than you might expect; shadows across the routing numbers at the bottom of the check or across the amount line will cause the software to reject the image.
Open the app, go to the deposit function, and align the front of the check inside the on-screen frame. Most apps auto-capture once the image is sharp and level. Flip the check and photograph the back, making sure the endorsement is fully legible.
The app will ask you to type the dollar amount even though the software already scanned it. That is a deliberate cross-check to catch misreads. If the written amount and the numerical amount on the check don’t match, the bank goes by the written amount, and the deposit may be rejected outright. Pick the account you want the money in, review the details, and submit.
You should get a confirmation screen within seconds, usually with a transaction ID. Save it. Many banks also send an email or push notification. Keep in mind that “received” means your images are in the queue, not that the check has cleared.
Businesses handling large check volumes typically use dedicated desktop scanners connected by USB rather than a phone camera. The same endorsement rules apply, and the bank provides setup guidance for supported scanner models.
Checks Your Bank May Not Accept Remotely
Banks decide individually which check types they accept through mobile deposit, and the exclusion lists are longer than most people expect. Commonly rejected items include:
- Third-party checks (made out to someone else who signed them over to you)
- Foreign-currency checks
- Money orders
- Checks older than six months
- Cashier’s checks and U.S. Treasury checks, at some banks
Other rejections are more mundane: a missing date, a payee name that doesn’t match your account name, or a check written to multiple people when not all of them are on the account. Anything unusual may require a trip to a branch or ATM.
When You Can Actually Spend the Money
How quickly the deposit becomes usable depends on federal law, the type of check, and your bank’s own policies. The baseline rules come from the Expedited Funds Availability Act, implemented through Regulation CC.3eCFR. 12 CFR Part 229 – Availability of Funds and Collection of Checks Regulation CC
The first $275 of a check deposit that isn’t already subject to next-day availability must be available by the next business day after the banking day you deposit it.4eCFR. 12 CFR 229.10 – Next-Day Availability The rest generally becomes available within two to five business days, depending on the check type.
One wrinkle matters specifically for mobile deposits. Several categories of checks that normally get next-day availability only get that treatment when deposited in person to a bank employee. Cashier’s checks, certified checks, state and local government checks, and U.S. Postal Service money orders all require an in-person deposit for next-day funds.4eCFR. 12 CFR 229.10 – Next-Day Availability Deposit a cashier’s check through your phone and the bank can hold it longer than it would at the counter. Your bank may also set its own timeline for mobile deposits beyond what the regulation requires, so check its disclosure.5Consumer Financial Protection Bureau. How Long Can a Bank or Credit Union Hold Funds I Deposited
Longer Holds Banks Can Apply
Banks can extend hold periods in specific situations. For deposits exceeding $6,725 in a single day, the amount above that threshold can be held for up to seven business days. New accounts (open fewer than 30 days) face tighter rules: only the first $6,725 of certain check types gets standard availability, and anything above that can be held up to nine business days.6eCFR. 12 CFR 229.13 – Exceptions Banks can also invoke exception holds for accounts with repeated overdrafts, checks they have reasonable cause to doubt, or redeposited checks that were previously returned unpaid. When they place an exception hold, they generally must notify you and tell you when the funds will be released.
Availability Is Not Clearance
This is where people lose money. Availability rules control when the bank must let you access the deposit. They say nothing about whether the check will ultimately clear. A check can bounce weeks after the funds appeared in your balance.
Scammers work this gap. They send a check (for a fake job, an “overpayment,” a loan qualification), you deposit it remotely, the money shows up, you spend it or wire part of it back, and days later the check is returned unpaid. The bank then debits your account for the full amount plus any returned-check fees. If your balance can’t cover it, you’re in overdraft. Banks can also close your account if they suspect involvement in the fraud, even when you were the target. The person who deposits a bad check bears the loss regardless of how they were tricked.
Deposit Limits
Every bank sets its own daily and monthly caps. For standard consumer accounts, daily limits typically run between $2,500 and $10,000, with long-standing customers sometimes qualifying for higher thresholds. Monthly limits often run two to four times the daily cap. These aren’t federally mandated numbers; they’re risk decisions each bank makes on its own, and they vary widely.
Business accounts work differently. Banks offering commercial remote deposit capture with dedicated scanner software set daily limits that can run well into six figures, sometimes with no monthly cap, usually for a monthly fee and under a separate agreement. If you process a high volume of checks, consumer mobile deposit won’t cover it.
If the App Rejects Your Deposit
Rejected deposits are common and almost always fixable. The usual causes are image quality (blurry text, shadows on the routing numbers, a corner cut off) and endorsement problems (missing signature, missing “For Mobile Deposit Only” language, wrong bank name). Amount mismatches, stale-dated checks, and payee-name mismatches also trigger rejections.
A rejection doesn’t void the check. You still have the paper. Fix what the app flagged and try again, or take it to a branch or ATM if the issue is something mobile deposit can’t handle, like a third-party check or a check type your bank excludes. A rejected mobile deposit doesn’t affect the check’s validity or your account standing.
What to Do With the Paper Check After Deposit
Once you have confirmation that the deposit was received, the paper check becomes a risk rather than an asset. You need to keep it briefly in case the bank has trouble processing the image, but you also need to make sure it can’t be deposited a second time. Write “VOID” or “DEPOSITED” across the front right away.
How long to keep it depends on your bank. Some say five days; others recommend 30 days. The mobile deposit agreement spells out the specific retention period. Once that window closes, shred the check with a cross-cut shredder. It carries your name, the payer’s account and routing numbers, and enough information to attempt fraud, so it doesn’t belong loose in the trash.
