About PCR QR Codes
A PCR QR code stores a structured text payload in the exact format you enter. Solancr does not reformat the content, because different lab and testing systems use different conventions. Whatever format your software expects, enter it as-is and the code will contain it exactly.
Because the payload is encoded directly into the pattern, the code works without any network or server. It can be scanned by a lab scanner or a phone and read as plain text.
Common Uses
- Sample tracking. Attach a code to a sample so scanning pulls up its metadata.
- Test result labels. Encode an identifier that links to a record in your system.
- Chain of custody. Encode a payload that records the sample's handling path.
- Batch processing. Label racks or plates with codes for automated readers.
- Internal workflows. Anywhere a structured payload needs to move between systems.
Payload Format
Solancr does not impose a format. The most common conventions in lab systems are:
- Key-value pairs with semicolons:
SampleID:12345;PatientID:ABC;Date:2026-01-01 - Pipe-separated fields:
12345|ABC|2026-01-01 - JSON:
{"SampleID":"12345","Date":"2026-01-01"} - Custom delimited strings specific to your lab's software
Enter the payload exactly as your downstream system expects. Any mismatch will cause the receiving software to reject the scan.
Tips for Reliable PCR Codes
- Keep the payload short. Dense QR patterns are harder for automated readers to scan reliably.
- Test the code with your actual scanner before printing in bulk.
- Avoid special characters that your scanner might misinterpret. Stick to ASCII where possible.
- Use a QR error correction level that matches your environment. Solancr uses medium (M) as a balance.
- Print at a size that matches the reading distance of your scanner.

Frequently Asked Questions
What is a PCR QR code?
It stores a structured payload in the format required by PCR (Polymerase Chain Reaction) testing systems. This is used in labs and testing workflows to pass sample metadata between systems.
What format should the payload be in?
The exact format depends on your lab's software. Common conventions are key-value pairs separated by semicolons or pipes. Enter the payload exactly as your system expects it.
Can I edit the payload later?
No. Static codes cannot be edited. If the payload changes, generate a new code and replace the print.
Is the PCR QR code free?
Yes. No signup, no watermark, and no scan limit.
Will the code work with automated lab scanners?
Yes. The code follows the standard QR format. Any scanner that reads QR codes can read this one.
Can I include line breaks in the payload?
Line breaks are supported and encoded as-is. Some scanners display them, others ignore them. If line breaks cause issues, use a single-line format.
