Certificate of authenticity with a QR code: what scanning it proves, and what it doesn't
On a Perfeito Studio certificate, the QR code opens the work's official page on perfeitostudio.com, which carries the medium, dimensions, year and Archive ID. Scanning it lets you compare the paper with a public record. It does not authenticate the paper, the painting or its value by itself.
What the QR code on the certificate opens
Amber Strata is built in horizontal passages of ochre, bone and oxidised umber on a canvas of 150 x 100 cm, and its certificate carries a QR code in the same way every certificate from the studio does. The studio describes it plainly: the code links to the official page of that specific work on perfeitostudio.com. A QR code is only a machine-readable way of writing a web address, so what it opens is an ordinary page on the studio's own site, not a separate verification service and not a database run by a third party.
That page is the studio's published record of the work. It carries the authoritative medium, dimensions, year, Archive ID, availability and price. For Amber Strata the Archive ID is AP-TAE-2026-004; for Prism Garden (acrylic on canvas, 100 x 100 cm, 2026) it is AP-LMR-2026-006; for Golden Passage (60 x 80 cm, 2025) it is AP-BNG-2025-001. The fields on the paper and the fields on the page are meant to be the same values, which is what makes the comparison useful.
What scanning it proves
Stated narrowly, scanning proves three things, and each is a fact about the page rather than about the object.
- The studio publishes a record under that Archive ID. If the code leads to a page on perfeitostudio.com showing the same title and Archive ID as the certificate, the paper refers to a work the studio has catalogued.
- The stated description is public and checkable. Title, series, year, medium and dimensions on the certificate can be set against the same fields on the page, line by line. A mismatch is a reason to write to the studio before anything else.
- The record is public, not only on the paper. The work's page can be reached from the studio's gallery without the printed code, so the description of the painting is not held only by the document.
The studio's own wording is that this makes provenance verifiable at any time. Read that as a statement about access to the record, which is exactly what a QR code can deliver.
What it does not prove
The limits matter more than the mechanism, because a QR code looks more technical than it is.
- It does not authenticate the paper. A QR code can be printed on any sheet. The artist's signature on the certificate is the representation itself; the code only points to a record.
- It does not confirm that the canvas in front of you is the one on the page. That check is physical: title, dimensions and surface against the photographs and description. The surface of a work such as Golden Passage, with sculpted texture paste and imitation gold leaf (metallic leaf), is hard to mistake for another painting once you compare it with the detail photographs.
- It does not show who owns the work today, and it is not a registry of title or a transfer of ownership. That is the job of the invoice and the acquisition agreement.
- It does not state value. The page gives the studio's price in Brazilian Real; it carries no appraisal and makes no statement about future worth.
- It has no legal weight of its own. What a signed certificate does or does not mean in law depends on the jurisdiction; see does a certificate of authenticity have legal weight.
How to tell the page is the studio's official one
The simplest check does not need the QR code at all: read the address. The official page sits under perfeitostudio.com, in the form perfeitostudio.com/{series-slug}/{work-slug}/, and the same page can be reached by browsing the studio's gallery. If the address after scanning is a different domain, or a shortened link, treat it as a reason to stop and ask, not to continue. Typing the address by hand, or opening the work from the gallery, reaches the same record without relying on the printed code.
A sensible way to use the page is as a second source. Compare the Archive ID, title, series, year, medium and dimensions on the certificate against the page, then against the painting. Three matching sources are stronger than any one of them, and a mismatch in any of the three is something to raise with the studio directly.
A QR code, an invoice and an agreement: three different jobs
The certificate is one document in a set. Every acquisition from the studio is made directly from the artist and includes the original, unique painting; a signed Certificate of Authenticity with the technical record and Archive ID; a fiscal invoice or official receipt; an Artwork Acquisition Agreement covering transfer of ownership, copyright and image use; an artist dossier; conservation and care guidance; and professional packaging.
So the QR code does not replace the invoice. The invoice records what was paid and is usually the document customs offices, insurers and accountants ask for; the agreement records the transfer of ownership; the certificate and its page identify the work. For a field-by-field reading of the certificate itself, see a real example, and for the eight elements any serious certificate should carry, what a certificate must include.
For those acquiring a work from abroad
Documents. Ask which document will carry the Archive ID of the work you are considering, and read that ID against the work's page before and after it arrives. Details. For buyers outside Brasília, additional detail photographs and video of a specific work are available on request through WhatsApp, which is the practical way to compare surface and scale. Shipping. The studio ships within Brazil and internationally. Freight is quoted per destination and paid by the buyer, as are any import duties and taxes in the destination country; professional packaging is included and transit insurance is available. International shipping is quoted on request, so ask for the quote and the schedule together. Details are on the shipping page.
From the studio
From the studio: the QR code as a reference to a detail sheet
Trained as an architect, I read the QR code the way I read a reference mark on a drawing sheet: it does not contain the information, it tells you which other sheet does. The certificate holds the signed statement; the page holds the full record, and the two are meant to say the same thing about the same canvas.
That is also why I would not ask the code to do more than that. A reference mark cannot certify the building. In the first body of work, painted between 2025 and 2026, each painting is unique and numbered under an Archive ID, and the pairing of a signed paper with a public page is the whole mechanism.
Frequently asked
What does the QR code on the certificate open?
It opens the official page of that specific work on perfeitostudio.com. The page carries the authoritative medium, dimensions, year, Archive ID, availability and price, so the printed certificate can be compared with a public record. The code leads to the studio's own site, not to a separate verification service.
Does a QR certificate replace an invoice?
No. The invoice records the payment and is the document customs offices, insurers and accountants usually ask for. The certificate and its QR code identify the work, and the acquisition agreement covers the transfer of ownership. Every acquisition from the studio includes a fiscal invoice or official receipt alongside the certificate.
How do I know the page is the studio's official one?
Read the address: the official pages sit under perfeitostudio.com, in the form perfeitostudio.com/{series-slug}/{work-slug}/. The same page can be reached from the studio's gallery without scanning anything. A different domain or a shortened link is a reason to stop and write to the studio before going further.
Does scanning the QR code prove the painting is genuine?
Not by itself. A QR code only leads to a record. It shows that the studio publishes a page under that Archive ID, and lets you compare title, year, medium and dimensions with the paper. Whether the canvas in front of you is that work is a physical check against the description and detail photographs.
What if the printed code does not work or the paper is lost?
The work's page can be reached without the code, through the gallery on perfeitostudio.com, and an Archive ID, which follows the format AP-XXX-YYYY-NNN, identifies the work in the studio's records. If you need help matching a document to a work, write to the studio over WhatsApp with the title and the Archive ID.
Does the QR code say what the painting is worth?
No. The page states the studio's own price in Brazilian Real and carries no appraisal. A certificate and its page record authorship, materials and description, and make no statement about future value; the studio does not set or quote secondary-market values.
Ask about the documents for a specific work
Write to the studio with the title of the work you are considering and ask which documents and detail photographs accompany it.
