Certificates of authenticity with QR and NFC

If you sell pieces that are valuable because they are authentic, your customer needs to be able to prove it, and you need to ensure that no one can counterfeit them.

A document with a signature can be copied in one minute. RKR Verify Authenticity It issues a digital certificate for each unit sold, with its own serial number, and a public verification page that can be accessed with a mobile phone: by scanning the QR code, bringing an NFC tag close or typing the code.

1 per unit
Each unit sold receives its own certificate, with its serial number, and is not duplicated if the order status changes.
23 topics
For the public verification page, with preview, without touching your store's theme.
QR + NFC
QR codes printed from the panel and NFC tags that pair with each certificate

/ It is issued only when the customer pays.

Art, limited editions, jewelry, collectibles: the certificate is issued with the sale and does not depend on you remembering to do it.

Automatic when paying for the order
A certificate is created for each unit of a certified product. If the order status changes multiple times, duplicates are not issued. You can also issue it manually from the product details page or the order.
Serial numbers with your rules
You define a template (default RKR-{YYYY}-{SEQ:5}) with counter, date, product, store or random blocks, and the preview shows you the result before saving.
Limited edition: No. X of N
The certificate indicates which piece it is within the series, so the buyer knows they have the 7th of 50 and not just any old one.
Author, work and own fields
Reusable author and artist profile, and custom fields (year, technique, dimensions, whatever you need) on each certificate.

/ A public page that anyone can check.

Anyone holding the item, or considering buying it second-hand, can scan the QR code or bring their mobile phone close to the NFC tag and instantly see if it's real.

Clear verdict
The page states whether the certificate is authentic, revoked, listed as lost, expired, or archived, along with the edition, author, and ownership history (with the owner's name masked).
QR code, NFC code, or serial number
Verification can be done via any of the four methods. Each query is logged (method, device, country) with a limit on the number of requests per IP address.
Footprint of integrity
Each certificate carries a SHA-256 fingerprint linked to the previous certificate for its product. If someone tampers with the database to change data, the website detects it as manipulation, and you can audit the chain from the dashboard.
Nobody prints a valid QR code without having one.
Searching by serial number gives the verdict, but it never reveals the code or the QR code. And your store's product page doesn't display the actual codes.

/ Ownership: the buyer owns and can resell

The buyer becomes the owner
Upon payment, the certificate is assigned to the customer's account. If the certificate was issued without an owner, claiming it requires the claim code that arrives in the mail or is included on the printed certificate.
Transfer upon resale
The owner initiates the transfer from their account, the recipient accepts it, and you can approve it beforehand if you wish. Unanswered requests expire automatically, and everything is recorded in the history.
Refund or cancellation = revocation
Optional: If the order is refunded or cancelled, your certificates are revoked and the public page no longer recognizes them.
My certificates, in My Account
Your customers can view and manage their certificates from their account, and can print the certificate with a secure link.

/ Labels that are stuck on the piece

QR code label sheets
Print sheets with QR codes (configurable columns, rows, margins, and template) from the certificate list, or a sample sheet to test beforehand.
NFC Tags
Match each tag with its certificate by UID, with batch import. The tag stores a single link to the public page, and compatible browsers can read it directly from the page.
Printable Certificate
A document ready to print or attach to the shipment.

/ Write with AI, if you want, and proofread before saving

It's optional and uses your own key: it works with OpenAI, Anthropic Claude, Google Gemini, Mistral, Groq, OpenRouter, DeepSeek, or any OpenAI-compatible service. It can generate certificate texts, translations, author biographies, and series rules. Nothing writes itselfEach proposal goes through a review screen where you mark what you accept, field by field.

/ Your brand, your style

23 themes and your own CSS
Colors, typography, radios, and effects for the verification page, with live preview. The CSS is published separately, so your store's theme remains untouched.
Statistics and verification records
Counters, graphs, and a list of each query with its result, to see how many times your parts are checked.
Integrated guide
22 sections within the panel that explain each function, plus a wizard with a list of steps to get started and demo data that can be removed with a button.

/ What worries you

Multistore and languages
Compatible with multiple stores and multiple languages. The module includes the panel and store in English and Spanish.
Security
The panel actions check the token, the public page limits requests per IP and is not indexed by search engines, and the printable document requires a link with its own token for each certificate.
What is sent to the AI?
Only if you activate it, and only for the specific information you request from your chosen provider. The key is stored on your server.
License and uninstallation
License AFL-3.0. When uninstalling, the certificate tables are preserved by default; the confirmation box allows you to delete them.

A digital certificate from the store, not an expert report. The module proves that a certificate was issued by your store, that it has not been altered, and who it belongs to; it does not, by itself, verify that a work is genuine, nor does it replace an expert appraisal.

Compatible with PrestaShop 1.7.8 to 9.2 · PHP 7.2 to 8.3

  • Reference
    rkrverifyauthenticity

v1.1.0

Complete review of the received module ( 1.0.34 ). Most importantly:

  • Integrity : Previously, each certificate's fingerprint included the module version, so any update would flag all certificates as "manipulated." This is no longer the case; updates now recalculate the fingerprints. The fingerprint is calculated based on the actual data stored in the database (previously, long text or text with quotation marks would flag it as "manipulated" immediately upon issuance).
  • Ownership security : Claiming an unassigned certificate now requires its claim code (from the purchase confirmation email or the printed certificate); previously, the serial number was sufficient. The token for store forms is linked to the visitor's session, and actions only accept POST (previously, a certificate could be stolen using a link). The transfer process verifies that the recipient genuinely accepts it, that the certificate still belongs to the sender and has not been revoked, and respects "store approval."
  • Public codes : the product page no longer displays the code or QR code of real certificates; searching by serial number provides the result but not the code, QR code, or printout. Notices from the certificate page are no longer included in the URL.
  • Issuance : "Issue upon order validation" did nothing (it read a non-existent key); without a serial number rule, all certificates were issued with the same number; a combination rule was applied to all combinations; saving the product rule resulted in a fatal error and overwrote the default rule; it was not possible to save from the product details page (it was a form within another form) or uncheck a box. With "Revoke upon refund," canceling or refunding the order revokes its certificates (the option existed but did nothing). Deleting a product's details page no longer archives the certificates for sold items.
  • Data : The JSON columns were saved empty (custom field options, AI headers, AI context and result, which is why it could never apply a suggestion). The author's biography retains its format.
  • Shop : The seal only appears on products eligible for certification (it used to appear on all of them), only once, and with its CSS and JS (which weren't loaded on the product page). "My Certificates" appears in My Account (Classic and Hummingbird). Texts with line breaks without
     in sight.
  • Back office : Actions that change data require profile edit permissions; all permissions are no longer granted to all profiles upon installation. The demo no longer issues demo certificates for real orders or deletes real statistics upon removal. Uninstalling preserves the certificates (they serve as proof of customer authenticity).
  • Mail with labels in the recipient's language, without duplicate shipments in transfers.
  • Multi-store: with "All stores" the default store is used, not store 1.
  • Clean Addon Validator (PHPStan included), AFL-3.0 license, PHP 7.2–8.3, tested on PrestaShop 1.7.8.11 , 8.2.8 , 9.0.0 and 9.2.0.
