Create a lot QR quickly
Start from fishery lot, processing lot, or general templates and turn lot data into a QR code immediately.
Балық шаруашылығы Traceability QR Generator (офлайн, Жеке деректер жоқ)
Create QR codes from lot information and check whether they can be scanned right away. It works without a network connection and does not send your енгізу to a server.
Anyone can read QR contents. If you are unsure, include only the lot ID and information that is қауіпсіз to publish.

What this page does
Shrink payload with compression
Use the public `fishery-v1` dictionary to shorten keys and improve scan stability.
Verify on the same screen
Check the generated QR right away with paste comparison or camera scanning.
Reuse history and templates
Keep recent entries and reusable templates on this device only, then duplicate old lots for new runs.
How to use it (3 steps)
- Choose a template, then enter the lot ID and any fields you need.
- Adjust compression, URL wrapping, hashing, error түзету, and quiet zone while watching the capacity meter.
- Before saving the QR, run a scan test with paste comparison or the camera.
Recommended items not to include
Anyone can read QR contents. Do not include personal data, direct contact details, confidential contract information, or internal URLs without authentication.
Мысалдар to avoid
- Names, phone numbers, email addresses, physical addresses, or social handles
- Detailed location data that could identify a private residence
- Private prices, contract numbers, internal URLs, or API keys
Safer replacements
- Use a worker ID or staff code instead of a name
- Use a port code, regional code, or prefecture instead of a detailed address
- Use a public help page URL instead of direct contact details
ЖҚС
The QR code does not scan well.
The payload may be too large, error түзету may be too high, or the print size may be too small. Turn on compression mode, shorten ескертпелер, and lower error түзету if needed.
I want scanning to open a web page.
Turn on URL wrapping. URLs often increase the character count, so if the capacity meter shows caution or danger, also reduce fields or increase the print size.
Can it sign the payload?
The first version can add a local hash, but it is not a cryptographic signature. A third party can still rebuild the payload in the same format.
Is my енгізу uploaded anywhere?
Жоқ. Everything runs in the браузер. History is stored only when you enable local content history on this device.
Маңызды ескертпелер
- Anyone can read QR contents. Do not include personal data or sensitive information.
- This tool helps traceability workflows, but it does not guarantee legal or standards compliance.
- The hash is only a reference for change detection. It is not authenticity proof or a signature.
