A digital check looks almost exactly like a paper check, just rendered on your screen. Open the file and you’ll see the payer’s name and address in the upper left, a check number in the upper right, a date line across the top, a “Pay to the order of” line through the middle, the dollar amount both in a box and written out in words, a MICR line of routing and account digits along the bottom, and a signature at the bottom right. The whole thing usually arrives as a PDF or high-resolution image through a secure link, not as a random email attachment.
That’s the short answer. The details below are what let you tell a legitimate one from a convincing fake.
The Front of a Digital Check
The layout is deliberately familiar. Payer name and address sit top-left. A check number appears top-right for tracking. The date runs along the top, and the payee line stretches across the center.
Every check shows the payment amount twice: as digits inside a box on the right, and spelled out in words on the line below the payee’s name. If those two ever disagree, the written-out amount is the one that controls.
Along the very bottom is the MICR line, printed in the same blocky font you’ve seen on paper checks. Reading left to right, it encodes three things: the nine-digit routing number that identifies the bank, the account number, and the check number repeated. On a digital check this line is just an image of the font rather than actual magnetic ink, but banks read it the same way during electronic processing.
The signature sits at the bottom right. On a digital check it’s typically a typed name, a stylized script rendering, or an image of a handwritten signature applied through the issuing software. A memo line to the left of the signature is where the payer notes what the payment is for.
Many digital checks also display a validity window somewhere on the face, such as “Void After 90 Days” or “Void After 180 Days.” Even without that stamp, the Uniform Commercial Code lets a bank refuse a check presented more than six months after its date.
The Back Side and Endorsement Area
Digital checks have a back, and it does real work. When a check is deposited by mobile app or processed electronically, the bank captures images of both sides. The back has to carry a legible endorsement from the payee, and for mobile deposits most banks require you to write “For Mobile Deposit Only” along with your signature and account number in the endorsement area. The Federal Reserve requires endorsement information to be legible on any check image submitted for electronic processing or adjustment.1Federal Reserve Services.

How It Arrives and What File You Get
Digital checks are usually delivered through email or text message containing a secure link. Clicking through takes you to an encrypted portal hosted by the payment processor, where you may need to enter a one-time passcode or answer a verification question before you can see the check. Once you’re authenticated, you can view the check image, download the file, or in some cases send the money straight to your bank account.
The download itself is typically a PDF or a high-resolution image. Viewed on a computer, the check often appears centered on a letter-size white background, formatted so you could print it at home if your bank accepts paper deposits. Mobile banking apps generally show it as a cropped image within their own interface.
The image has to meet quality standards set under the Check 21 Act, the federal law that lets banks process check images instead of shuttling paper.2Board of Governors of the Federal Reserve System. Frequently Asked Questions About Check 21 and Substitute Checks When a bank creates a “substitute check” from a digital image, that paper reproduction is legally equivalent to the original. So a printed digital check you deposit at a branch, or the image your bank converts for clearing, carries the same legal force as a check written by hand.
Security Features Built Into the Image
A legitimate digital check has security features baked into the file itself, not just the delivery. The common ones:
- Visible watermarks across the body of the check.
- Microprint patterns, often along the signature line or border, that degrade into blur when copied.
- QR codes or barcodes that link to verification data when scanned.
- A “Void” pantograph in the background, designed to stay hidden during normal viewing but appear if the check is photocopied or screenshotted.
None of these are foolproof on their own. Businesses that issue digital checks often layer on Positive Pay: the issuer uploads a file to their bank listing every check written, including check number, amount, and payee name, and the bank flags anything that doesn’t match when it comes in for payment.
Forging or altering a digital check’s security features, account information, or signature can trigger federal charges. Fraud involving access devices such as account numbers carries up to ten years in prison for a first offense,3Office of the Law Revision Counsel. 18 USC Chapter 47 – Fraud and False Statements and the general federal sentencing statute sets the maximum fine for any felony at $250,000 for an individual.4Office of the Law Revision Counsel. 18 US Code 3571 – Sentence of Fine
How to Tell a Real Digital Check From a Fake
Fake digital checks can look immaculate. The image may show watermarks, a valid-looking MICR line, and a real bank’s name, and the deposit can appear to clear in your account within a day or two. Then, weeks later, the issuing bank rejects it, your bank claws the money back, and you’re on the hook for anything you already spent or sent.
What to check before you trust the image:
- Delivery method. A real digital check from a reputable platform arrives through a secure portal with authentication. A PDF landing in your inbox from someone you don’t know is a warning sign, not a payment.
- Who sent it. Unsolicited checks from strangers, or from parties you’ve been talking with only briefly online, are the classic scam setup.
- The amount. Checks written for more than you agreed to, paired with a request to wire back the difference, are the overpayment scam. The check is fake even when it briefly appears to clear.
- Pressure to act fast. Legitimate payers don’t rush you to deposit and forward funds within hours.
- The account it’s drawn on. Unfamiliar bank names, or accounts that look recently opened, warrant a call to the issuing bank before you touch the check. Use the phone number on the bank’s own website, not any number printed on the check image.
- The two amounts match. The digits in the box and the words below the payee line should agree. A mismatch is either an error or a manipulation.
- The MICR line looks right. Nine digits for the routing number, followed by the account number and the check number. Missing or malformed digits are a tell.
A digital check that appears to clear is not the same as a digital check that has actually cleared. Funds availability under federal rules is a bank’s promise to let you access money, not a guarantee the check is good. Spending against an unverified deposit is where most check scam victims get burned.
Digital Check, eCheck, or ACH Transfer
People often mix these terms up, and the differences matter for what you’re actually looking at.
“Digital check” and “eCheck” usually describe the same thing: a check-like payment created electronically, presented as a check image, and processed through the ACH (Automated Clearing House) network. Both pull your bank’s routing and account numbers from the MICR line, and both typically clear within one to five business days.
A standard ACH transfer uses the same underlying network but doesn’t produce a check image at all. It’s the mechanism behind recurring bill payments and direct-deposited paychecks, generally set up as an ongoing authorization, and it tends to settle in one to three business days. Per-transaction costs run under $0.50 or nothing at many banks, versus roughly $0.20 to $1.50 for an eCheck.
So if you’re staring at a payment that looks like a check on screen, complete with payee line and MICR strip, you’re looking at a digital check or eCheck. If money simply appears in or leaves your account with no image attached, that’s an ACH transfer.
