The QR toolkit for small businesses

Built for freelancers, shops and service businesses. Scanning, QR codes, contacts and history work the moment you open it — no account. Sign in with Google only to publish your BizCard or a letter, or to back up. Every tool below also runs in your browser — pick one to jump straight in.

BizCard

Your digital visiting card at one permanent link: photo, role, phone, email and links, plus Pay with UPI and Leave a review buttons. Edit it any time — every QR you ever printed shows the latest version.

Teky Letters

A private letter behind an ordinary QR code, for a thank-you, an invitation or a birthday. It unlocks with a word only the two of you know, and it is encrypted before it leaves your device.

BizCard

One card. Every phone. No app on their side.

Your name, role, contact details and links at one address you hand out as a QR code, a link on WhatsApp or an NFC tag. Whoever scans it opens the card in their browser and saves you to their contacts in one tap.

  • Pay with UPI and Leave a review buttons, right on the card
  • Edit any time — printed codes never go stale
  • An offline contact QR for places with no signal
  • Card images in eight styles for print and social posts

Codes that look like they belong to you

Most QR generators give you a black square. This one gives you a live preview and every dial worth having, then exports at a resolution you can actually print.

  • Square or rounded modules, square or circular finder eyes
  • Drop in a logo — error correction jumps to High so it still scans
  • Save to your gallery, share it, or download it on the web

Teky Letters · try it right here

This is what your recipient sees

No install, no sign-up — the same lock screen a scanned code opens.

The word is the key — literally

There is no password stored anywhere to check your guess against. The word you type derives the decryption key. Get it wrong and there is simply nothing to read; get it right and the letter appears.

Demo secret word: forever — try a wrong one first.

Guides

Up and running in four steps

Pick what you came for. Each one takes about a minute.

1

Sign in once

A BizCard lives at a public link, so publishing it needs an account. Tap My card and sign in with Google. Everything else works without one.

2

Fill in your details

Add your photo, name, role, company, phone, email and links. Add a UPI ID and your Google review link to show Pay with UPI and Leave a review buttons.

3

Publish and share

Publish to get your permanent link and QR. Send it on WhatsApp, show the QR, save a card image, or write it to an NFC tag on Android.

4

Edit whenever

Change your number or job and just update the card. Every QR and tag already out in the world opens the new details.

Private by design

Your letter is sealed before it leaves your phone

This isn't a server checking a password. The message is encrypted on your device, and what we store cannot be read by us, by an administrator with console access, or by anyone who breached the database.

You write

The message and your secret word exist only in the app, on your phone.

The phone seals it

Your word derives a key — PBKDF2-HMAC-SHA256, 210,000 iterations — and AES-256-GCM locks the letter.

We store ciphertext

Only the sealed envelope, a salt and a nonce. Never the message, never the word, never a hash of it.

They unlock it

Their browser derives the same key from the word you told them and decrypts it locally. A wrong word simply fails.

Contacts stay on your phone unless you turn on backup Paper cards are read on your phone, never uploaded No ads, and analytics that never see your content No account for scanning, QR codes, contacts or history

Questions

Straight answers

The things people ask before they start.

What is BizQR Teky?

A free app for small businesses and professionals. It gives you a digital business card (BizCard) at one permanent link, a contact book for the cards you collect, Google review QR stands, ready-made business QR codes for WhatsApp, UPI, Wi-Fi and more, a QR studio, and secret letters. It runs on Android and in any web browser.

Is it free?

Yes. It is free on Google Play and on the web, with no ads. Contacts are unlimited and there is nothing to unlock.

Do I need an account?

Not for scanning, the QR Kit, QR Studio, Contacts or history — those work straight away. You sign in with Google only to publish a BizCard or a letter, or to back up your contacts and history to your own account.

Does the person receiving my BizCard need the app?

No. They scan the QR with any phone camera, or open the link, and your card opens in their browser. One tap saves you to their contacts. No install, no account.

Can I use BizQR Teky on a computer?

Yes. Open the web app in any modern browser for your BizCard, Contacts, QR Kit, the review kit, QR Studio and Letters. Writing NFC tags and reading paper visiting cards need the Android app; scanning works in the browser once you allow the camera.

How does the Google review QR work?

You paste the review link from your Google Business Profile once. The app turns it into a QR and print-ready templates — counter card, table tent, poster, stickers and business-card backs. Customers scan it and land on your review form.

Can customers pay me with the UPI QR?

The UPI payment code opens any UPI app with your UPI ID and name filled in, and your BizCard can show a Pay with UPI button. The money goes straight to your bank through UPI; BizQR Teky never handles payments.

Are my contacts uploaded anywhere?

No, unless you switch backup on yourself. Contacts are stored on your device, and paper visiting cards are read on your phone without uploading the photo. Backup is off until you enable it, and it syncs to your own private account area.

What is a secret letter, and can anyone else read it?

It is a private message hidden behind a QR code that opens only with a secret word. The message is sealed on your device with AES-256-GCM using a key derived from that word (PBKDF2-HMAC-SHA256, 210,000 iterations), so what is stored cannot be read by us or anyone who breached the database. Nobody can recover the word if you forget it.

Does the app track what I scan or write?

The Android app uses Microsoft Clarity to see which screens people use and where they get stuck, with masking applied to the entire app, so the text you type and the images on screen are obscured before anything is sent — your letters, secret words, contact details and the contents of codes you scan never leave your device. The web app does not record sessions. There is no advertising SDK.
