About Our QR Codes

We do QR codes for a living and have been at the forefront of QR code technology since we started in late 2007.

We don't use the Google Charts API for QR Code generation - we've gone to the trouble of building and developing a custom ISO-compliant alogorithm - so we aren't bound by the data type, image size and resolution limits imposed by other sites that use somebody else's third-party generator as their back-end.

Batch Processing

Upload a single TSV file containing the details of up to 500 individual QR codes and process them as a single batch. Once processing has been completed a single ZIP file containing a image file for each of the QR codes in the batch can be downloaded or sent by email.

QR code image size, resolution, output file format (raster or vector) and colour can be specified for the QR codes in a batch. Batch processing directly supports our main data types and QR codes within a single batch can be mixed format.

Processing Large Batches

The maximum online batch size limit of 500 codes per batch has been set to avoid undue server load across the sessions of other users. For registered users with more than 20,000 codes to generate we offer a service whereby the job is run locally at our end - the cost of this service is:

US$2.50/1000 codes

(a reduced rate of US$1.10/1000 applies for jobs involving >100,000 codes)

+

US$130

processing fee

Just send us the TSV or Excel file containing your batch data and we'll look after the rest. The QR code image files for the batch are then emailed to you in zip files.

Payment is by Paypal prior to job commencement and turnaround is 48-72 hours from when payment has been received. Send us an email for more information.
