Terms of Service
Effective Date: March 10, 2026 | Last Updated: March 10, 2026
These Terms of Service ("Terms") govern your access to and use of the VerifiedKnock pre-arrival authentication platform, including all associated software, hardware, APIs, and services (collectively, "the Service"), operated by VerifiedKnock, Inc. ("VerifiedKnock," "we," "our," or "us"). By accessing or using the Service, you agree to be bound by these Terms.
Critical Limitation — Identity vs. Behavior
VerifiedKnock verifies IDENTITY, not BEHAVIOR, CHARACTER, or INTENT.
A positive verification result confirms only that the person presenting the NFC credential is the registered officer whose public key is bound to that card. It does not constitute a background check, a guarantee of safety, an endorsement of the individual's conduct, or a representation that the individual poses no threat. Users must exercise independent judgment at all times. VerifiedKnock is not liable for the actions of any verified individual.
1. Acceptance of Terms
By creating an account, purchasing a subscription, enrolling an officer, or otherwise accessing the Service, you represent that: (a) you are authorized to enter into this agreement on behalf of your organization; (b) your organization is a legitimate law enforcement agency, licensed utility, licensed contractor, or authorized healthcare organization; and (c) you agree to comply with these Terms and all applicable laws.
If you do not agree to these Terms, you may not access or use the Service. We reserve the right to update these Terms at any time with 30 days' notice for material changes.
2. Biometric Data — Agency Obligations
The VerifiedKnock NFC card stores a fingerprint template within its tamper-proof secure element. VerifiedKnock does not collect or process this biometric data. However, the agency deploying the cards is the data controller and bears the following obligations:
Illinois (BIPA — 740 ILCS 14):
Before enrolling any officer's fingerprint, the agency must: (a) inform the officer in writing that biometric data is being collected and the specific purpose and length of term for which it is being collected; (b) obtain a written release signed by the officer; and (c) maintain a publicly available written policy establishing a retention schedule and guidelines for permanent destruction of biometric data. Failure to comply may result in statutory damages of $1,000–$5,000 per violation under BIPA § 20.
Texas (CUBI — Tex. Bus. & Com. Code § 503.001):
The agency must inform the officer before capturing biometric data and obtain consent. Biometric identifiers may not be sold, leased, or disclosed to third parties without consent, except as permitted by law.
Washington (HB 1493 / RCW 19.375):
The agency must obtain consent before enrolling biometric data, provide notice of the specific purpose and retention period, and allow individuals to request deletion of their biometric data.
By using the Service, the agency represents that it has obtained all required consents and maintains all required written policies for each enrolled officer. VerifiedKnock provides template consent forms upon request at [email protected].
3. Permitted Use
The Service is licensed, not sold, for use solely by verified partner agencies for the purpose of authenticating authorized personnel prior to residential or commercial interaction. You agree not to:
Use the Service to verify individuals for purposes other than pre-arrival identity confirmation in connection with legitimate official duties.
Attempt to reverse-engineer, decompile, or extract cryptographic keys from VerifiedKnock hardware or software.
Share NFC cards between officers or allow an officer to use another officer's credential.
Use the Service in any way that violates applicable federal, state, or local law, including laws governing law enforcement conduct, privacy, and civil rights.
Misrepresent the capabilities of the Service to residents, including claiming that a positive verification guarantees safety.
Interfere with or disrupt the integrity or performance of the Service or the Card Revocation List (CRL).
4. Subscriptions and Payment
Access to the Service requires a paid subscription. Subscription fees are billed in advance on a monthly or annual basis. All fees are non-refundable except as required by law or as expressly stated in a separate written agreement.
Payment is processed by Stripe, Inc. By providing payment information, you authorize VerifiedKnock to charge your payment method for all fees incurred. If a payment fails, your agency's subscription will be marked "past due" and officer verification capabilities may be suspended after a 7-day grace period.
We reserve the right to modify pricing with 30 days' written notice. Continued use of the Service after a price change constitutes acceptance of the new pricing.
5. Hardware and NFC Cards
NFC hardware cards are sold separately and are subject to a separate hardware agreement. Cards remain the property of the agency upon purchase. The agency is responsible for physical security of all issued cards. Lost or stolen cards must be reported immediately so VerifiedKnock can add the card UID to the Card Revocation List (CRL).
VerifiedKnock is not liable for unauthorized use of a card that has not been reported as lost or stolen. The agency assumes full responsibility for all verifications performed using cards under its account until revocation is confirmed in the system.
6. Limitation of Liability
TO THE MAXIMUM EXTENT PERMITTED BY APPLICABLE LAW, VERIFIEDKNOCK AND ITS OFFICERS, DIRECTORS, EMPLOYEES, AGENTS, AND LICENSORS SHALL NOT BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, PUNITIVE, OR EXEMPLARY DAMAGES, INCLUDING BUT NOT LIMITED TO DAMAGES FOR LOSS OF PROFITS, GOODWILL, USE, DATA, OR OTHER INTANGIBLE LOSSES, ARISING OUT OF OR IN CONNECTION WITH:
The actions, omissions, or conduct of any individual verified by the Service.
Any reliance placed on the completeness, accuracy, or existence of any verification result.
Unauthorized access to or alteration of your transmissions or data.
Any failure or interruption of the Service, including failure of the Card Revocation List to update in real time.
Any decision made by a resident to interact or not interact with a visitor based on a verification result. VerifiedKnock does not instruct residents to open their door and assumes no liability for any physical interaction that occurs.
IN NO EVENT SHALL VERIFIEDKNOCK'S TOTAL LIABILITY TO YOU FOR ALL CLAIMS EXCEED THE AMOUNT PAID BY YOU TO VERIFIEDKNOCK IN THE 12 MONTHS PRECEDING THE CLAIM.
7. Indemnification
You agree to indemnify, defend, and hold harmless VerifiedKnock and its officers, directors, employees, and agents from and against any claims, liabilities, damages, judgments, awards, losses, costs, expenses, or fees (including reasonable attorneys' fees) arising out of or relating to: (a) your violation of these Terms; (b) your use of the Service; (c) your failure to obtain required biometric consents from enrolled officers; (d) any claim by an enrolled officer or third party arising from your use of the Service; or (e) your violation of any applicable law or regulation.
8. Intellectual Property
The Service, including all software, cryptographic protocols, hardware designs, trademarks, and content, is owned by VerifiedKnock and protected by U.S. and international intellectual property laws. The VerifiedKnock name, logo, and hexagonal sticker design are trademarks of VerifiedKnock, Inc. The underlying authentication system is the subject of a pending U.S. patent application. You are granted a limited, non-exclusive, non-transferable license to use the Service solely for its intended purpose during the term of your subscription. No other rights are granted.
9. Governing Law and Dispute Resolution
These Terms shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to its conflict of law provisions. Any dispute arising out of or relating to these Terms or the Service shall be resolved by binding arbitration administered by the American Arbitration Association under its Commercial Arbitration Rules, except that either party may seek injunctive or other equitable relief in any court of competent jurisdiction.
Notwithstanding the foregoing, claims under Illinois BIPA shall be governed by Illinois law and may be brought in the Circuit Court of Cook County, Illinois, or any other court of competent jurisdiction in Illinois, as required by BIPA § 20.
10. Termination
Either party may terminate the subscription with 30 days' written notice. VerifiedKnock may terminate or suspend access immediately, without prior notice or liability, if you materially breach these Terms, fail to pay fees after the grace period, or engage in conduct that poses a risk to the security or integrity of the Service.
Upon termination: (a) your access to the Service will be revoked; (b) all officer cards under your account will be added to the CRL; (c) you must destroy or return all NFC hardware as specified in your hardware agreement; and (d) sections 2, 6, 7, 8, 9, and this section 10 shall survive termination.
11. Disclaimer of Warranties
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, AND UNINTERRUPTED OR ERROR-FREE OPERATION. VERIFIEDKNOCK DOES NOT WARRANT THAT THE SERVICE WILL MEET YOUR REQUIREMENTS OR THAT THE CARD REVOCATION LIST WILL BE UPDATED IN REAL TIME UNDER ALL CIRCUMSTANCES.
