Everything a printed code should be able to do
Once a code is on a menu, a box, or a billboard, reprinting is the expensive part. Dynamic links move the decisions into your account instead.
Per-scan analytics
ProEvery scan recorded with approximate city, device, OS, and time, exportable to CSV. Free plans keep aggregate counts by day, device, and country.
Repoint any time
FreeChange where a printed code goes in seconds. 3 links free with unlimited scans; unlimited links on Pro.
Your domain on the code
ProScanners see your name, not ours, with custom endings you choose instead of a random slug.
A file behind the code
ProHost a PDF or image at the code itself and swap the file without reprinting. Menus, spec sheets, price lists.
replaced, same code
Smart routing
ProOne code, many destinations: route each scan by country, language, device platform, or time of day.
Link pages
ProA hosted page of up to 12 link buttons behind one code, editable any time. One QR for everything you do.
Made in your browser
Static codes are generated entirely on your device. Nothing is uploaded unless you create a dynamic link or host a file, and we say exactly what those store.
No scan-count paywall
Free dynamic links have unlimited scans and no expiry. A code you printed keeps working; we do not hold it hostage.
Data you can erase
Free plans keep aggregate counts only. Pro per-scan records are kept about 90 days, and you can export or delete them at any time.

One place to create, design, and download: the Studio. Dynamic codes you can change after printing, plus free static codes for URLs, Wi-Fi, vCards, text, email, SMS, phone, events, locations, and crypto.

How a crypto QR code works
A crypto QR code encodes a payment link: bitcoin:bc1q…?amount=0.001 for Bitcoin (the BIP-21 format) or ethereum:0x… for Ethereum. Wallet apps recognize these on scan and prefill the recipient address, and optionally the amount, in the send screen. The sender still reviews and confirms the transaction in their own wallet; a QR code can never move funds by itself.
Since one wrong character in a pasted address sends funds into the void, scanning instead of typing isn't just convenient; it's the safer way to share an address. Common uses: tip jars, donation posters, invoices, merch tables, and stream overlays.
Filling in the fields
Pick the coin, paste your receiving address (a bc1…/1…/3… address for Bitcoin, 0x… for Ethereum), and optionally set an amount, useful for fixed-price invoices, and the sender can still edit it. Bitcoin codes also take an optional label that many wallets show alongside the payment ("Coffee fund").
Safety notes
Your address is public information: printing it exposes nothing a blockchain explorer wouldn't; a receiving address can never be used to withdraw. The thing to be careful about is accuracy: always test-scan with your own wallet and verify the address matches before printing, and check the first and last few characters of the address on the printed piece. Reticle generates the code entirely in your browser; your address is never uploaded.
Frequently asked questions
Which cryptocurrencies are supported?
Bitcoin and Ethereum. Bitcoin codes use the BIP-21 payment format with optional amount and label; Ethereum codes carry the address with an optional amount.
Is it safe to print my wallet address on a poster?
Yes, a receiving address is public information, and knowing it never allows withdrawals. The real risk is a wrong address, so test-scan the code with your own wallet and verify the characters before printing.
Does the amount lock what the sender pays?
No, it prefills the amount in their wallet as a convenience, and they can edit it before confirming. For fixed invoices, state the amount on the sign too.
Can a QR code take money from someone who scans it?
No. The code only prefills a payment the sender must review and confirm in their own wallet. Nothing is transferred by scanning.
Is my address uploaded or stored anywhere?
No. The code is generated entirely in your browser; your address never leaves your device unless you sign in and explicitly save the code.
