Used cars
A signed walk-around showing the VIN, odometer, body condition, and a current newspaper or date stamp. Buyers send deposits faster. You stop driving to no-shows.
Real listings · More leads
Attach a Prson reality-proof to your car, apartment, or product listing — a signed live walkthrough that anyone can verify. Buyers commit faster, scams get filtered out, and qualified leads stop scrolling past you.
The trust gap
Every marketplace, from used cars to short-term rentals to handcrafted electronics, is full of the same friction: a buyer sees a listing, can't tell if it's real, sends three messages asking for more photos, gets an awkward Friday-night Zoom call, and still wires a deposit holding their breath. Most sellers are honest — the dishonest few are the reason every transaction is slower and more anxious than it needs to be.
A reality-proof link cuts through that. One scan, and the buyer sees a signed walkthrough that can't be lifted from anyone else's listing, can't be staged from stock photos, and can't be replayed by a second seller. They commit, or they move on quickly — either way, you spend zero time on the wrong leads.
How it works
In the Prson app, pick the item or property and capture a live photo or video — up to 6 minutes. The bytes are hashed and signed by your identity key before they leave the phone.
Prson returns a short URL or QR code. Paste it into your listing's description, your marketplace bio, or right next to the asking price. No app required to view — buyers tap the link in any browser.
Anyone scanning the link sees the walkthrough plus a green "verified by Prson" stamp. The capture is bound to your identity — they know who recorded it, when, and that it hasn't been edited since.
Serious buyers can also ask for a new prompt-bound challenge: "show the dashboard reading today's date" or "open the storage room I asked about." A fresh signed capture, on the spot.
What a reality-proof shows
A real walkthrough recorded in-app. No camera-roll uploads, no stock photos, no AI-generated room renders. The footage exists because someone with the seller's key made it.
The capture carries the seller's signed identity — name fragment, country, "verified human" status — at whatever level of disclosure they chose. Buyers know they're dealing with a real person, even if they don't know their full name.
The file hash plus the signature live on the proof page. A buyer who downloads the file can verify months later, offline, that nothing about it has changed.
Examples
A signed walk-around showing the VIN, odometer, body condition, and a current newspaper or date stamp. Buyers send deposits faster. You stop driving to no-shows.
A live pan from the front door across the living room and out the window — the most effective answer to "is this actually the place I'd be renting?" ever invented.
Power it on, show the serial number, scroll through the settings screen. Removes the "I'll buy if it boots" back-and-forth and tells re-sellers from real owners apart.
Photographers, contractors, repairmen, trainers — show your studio, your tools, your last finished project. Bookings go up because the buyer can tell, in 30 seconds, that you exist.
Show the workshop, the work-in-progress, the materials. Wholesalers and dropshippers can't fake it — independent makers stop competing on the same axis.
Where small details matter — coin grades, watch movements, signed memorabilia — a signed close-up walkthrough is the difference between a winning bid and a lurker.
Why sellers care
Tire-kickers, scammers, and "is this still available?" spammers move on quickly when the listing's headline proof says everything they would've asked for.
A reality-proof badge on your listing is the same differentiator a verified-merchant tick used to be — except buyers don't have to trust a platform, they trust the signature.
The same proof link works on classified sites, social DMs, WhatsApp listings, and your own page. One capture, everywhere you advertise.
