CHECK VERIFICATION

What the Print Checks Now verification QR actually verifies.

A successful result confirms a Print Checks Now registration and the integrity of four QR-signed fields. It is a comparison aid—not a guarantee that the paper check is genuine, funded, authorized, or collectible.

REGISTERED FIELDS MATCH

Now compare the paper yourself.

On a real result, the recipient must compare payee, amount, date, and check number with the physical check. If anything differs, do not accept it.

THE BOUNDARY

What it confirms—and what remains your job.

Verification can confirm

  • The QR's cryptographic signature is valid.
  • The verification identifier is registered with Print Checks Now.
  • The registration status is valid, voided, or recalled.
  • The QR-signed payee, amount, date, and check number have not changed inside the link.

Verification cannot confirm

  • Who physically handed or mailed the check.
  • Account ownership, status, available funds, or eventual clearance.
  • Signature authority, endorsements, paper, ink, or fields not displayed.
  • Bank acceptance or whether a physical check has been washed or altered elsewhere.

RESULT STATES

Let the status choose the next action.

ResultWhat to do
Valid registrationThe QR signature and registration match. Compare every displayed field with the paper before accepting it.
VoidedDo not accept the check. The sender marked its registration void.
RecalledDo not accept the check. Contact the sender using a trusted channel.
Not registered or invalid linkDo not treat the QR as verification. Confirm the check independently with the sender and bank.
Temporarily unavailableTry again later. Do not rely on an incomplete result.

PRIVACY ARCHITECTURE

The signed fields travel in the QR link fragment.

URL fragments—the part after #—stay in the browser and are not sent in an ordinary page request.
ON THE QRSigned field details

Verification ID, payee, amount, date, check number, and cryptographic signature.

ON THE SERVICELimited registration record

Identifier, hashes, status, timestamps, lookup count, and optional file hash—not the plain payee or amount.

IN YOUR BROWSERComparison and signature check

The page reads the fragment, checks the signature, retrieves status, and shows the four fields for a human comparison.

The public verification key is available at the official key endpoint. Technical availability does not change the physical-check limitations above.

SAFER ACCEPTANCE

Questions recipients should ask.

Does “registered fields match” mean the check will clear?

No. It does not prove available funds, account status, authorization, bank acceptance, or eventual clearance.

Can a copied QR make a fraudulent check legitimate?

No. A copied code can repeat signed data, but it cannot prove that an unrelated piece of paper is genuine. Compare every displayed field and evaluate the sender and transaction independently.

Does verification detect check washing?

This cannot detect check washing. It does not inspect paper, ink, handwriting, endorsements, signature authority, or fields not shown. Differences in the four displayed fields are a reason to reject the check, but a match does not eliminate other fraud.

What if the QR is damaged or unavailable?

Do not treat it as verified. Contact the sender through a known channel and independently confirm the payment with the issuing bank.
