ka-CHOP! 🏁 the sound of your stamp hitting the paper
Snap your IC, passport or licence. Kachop stamps it with who it's for, why, and when — then you share a copy that can't be reused for a loan you never applied for. The unstamped original never leaves your phone.
No more emailing a clean scan of your IC to a stranger. Kachop is the photocopy-with-attitude, in your pocket.
The scanner finds the document's edges itself and perspective-crops it. Point it at the sky and it captures nothing — we're not that kind of app.
The stamp is burned into the pixels: purpose, recipient, date and "COPY — NOT VALID FOR OTHER USE". Front and back land in one PDF.
WhatsApp, email, AirDrop — one tap. The stamped render is the only thing that ever leaves your phone. The original is never uploaded.
Five stamped copies are free — no card required. Then pick a lane: subscribe, buy a lifetime pass, or grab a pack of stamps.
Prefer to pay as you go? Stamp packs: 5 for $2.99 · 15 for $6.99 · 50 for $19.99.
Identity-copy fraud is real — fraudsters reuse clean scans of IDs to open accounts, loans and phone plans in your name. Kachop follows the discipline that regulators in India and Singapore already recommend: purpose-bound, masked-style copies.
The unstamped photo never leaves your phone. Only the stamped render is ever uploaded.
Recipient + purpose + date are burned into the pixels, so reusing the copy elsewhere is visibly wrong.
Delete your account from the app and your profile, copies and history are erased.
Edge detection runs on your phone via ML Kit — no cloud scanning of your document.
A pixel stamp is deterrence plus declared-purpose evidence — it makes misuse obvious, not impossible. We never claim "fraud-proof". That's why the original stays off the internet entirely.
"Chop" is Malaysian/Singapore English for stamping a document. Ka-chop is the sound it makes. Ka-chow, but for paper. 🏁
Yes — IC, licence and cards scan front and back, and both sides export as a single PDF at the document's real physical size. Passport and other documents are single-page.
No — build your stamped copy first, and only sign in when you're ready to send it.
Five copies are on the house. The sixth one will still be cheap.
