    Generating Barcodes

    Note: If your database is empty, you’ll first need to fill it either with values directly entered or autofilled. This tutorial shows you only how to view and save those values as barcode images.

    It is important to note you do not need to use barcodes or QR codes generated by the codeREADr platform. In fact, most clients generate and print their own barcodes and just upload the barcode values to databases on our servers.

    If you prefer, you can use codeREADr to generate QR code images and then merge the images into printed media and/or electronic media (email, web, etc.). You then can distribute the images with whatever tools you have for your application.

    View and Save One Barcode at a Time

    To generate barcodes through the database menu, do the following:

    1. First, click on the ‘Databases’ link on the navigation menu.
    2. Second, click on the database (or its Edit button) from which you would like to generate barcodes.
    3. Third, click on the barcode link on the top right side of any barcode value entry to generate a barcode image.

    You can right click to “Save Image As”

    Bulk Export Barcode Images

    QR code images can be exported in bulk from the Databases page or the Tasks page.

    1. Click “Export Barcodes” on the Tasks page and we will send you an email with a link to download a ZIP file. From there you can extract your QR codes and merge them into emails using your email service provider.
    2. Alternatively, click on the “Export” tab of your Database and select to download the images as a ZIP file directly.

    Standard vs. Branded Barcodes

    Without a paid plan you can generate both Standard and Branded QR codes for testing purposes. A Standard QR code includes just the QR code and associated human-readable text. Branded QR codes can be customized with an image and text.

    If you’ve signed up for at least a 5-Device paid plan, you can generate a large number of QR codes. You can upgrade to a paid plan and downgrade back to the Free Plan as needed.

    There is a limit of 100MB per generation request. The number of QR codes that limit represents depends on the image used and the QR code size. The typical size for a Standard QR code is 5KB. The typical size of a Branded QR code is 25KB (assumes small image size – e.g. 120×120 pixels).

    • Standard ~ 20,000 QR codes (typical).
    • Branded ~ 4,000 QR codes (typical)

    If the number of values in your database could create an export file larger than the 100MB limit, please contact Learn more about branded QR codes.

    Printing Barcodes

    1. Buy a desktop program like iBarcoder for PC and MAC (<$50) or a program like those offered by ID Automation.
    2. Buy custom labels from a label printer like ImageTek ($150 for 1,500 labels). Note: there are many excellent label printers globally. Ideally, look for ones that can print variable data QR codes or Code 128 barcodes as they are the best for scanning.
    3. Buy a label printer desktop or portable label printer from companies like Dymo. They have PC/MAC connected printers like the LabelWriter 450 and mobile Rhino Industrial 4200 and similar models. Also, these devices can print Code 39 and Code 128 barcodes. Importantly, we would recommend Code 128.
    4. Buy our pre-printed labels with database ($49.95 for 1,000 labels).
    5. Buy variable data plastic cards with barcodes printed by suppliers like Plastic Printers, costing roughly $0.50 to $2.50 per card depending on volume and type. Also, embedded RFID/NFC chips are available.
    6. Buy wristbands with QR codes, barcodes, or RFID/NFC chips from suppliers like ID & C. Importantly, they supply wristbands for large and small events alike, including some of the world’s largest festivals.

    Further Recommendations and Suggestions

    If you can choose the type of barcode to use, we highly recommend 2D barcodes for accuracy and speed, especially QR codes. However, codeREADr can scan up to 50 different barcode languages. So we’ve got you covered!

    Importantly, if you order QR Code labels from a printing company, be sure they use Model 2. Also, before deploying your 1D or 2D barcode labels, test scanning with the iOS and/or Android OS devices you plan to use.

    You can use mail merge to insert your exported images into documents, emails, etc.

    To print them on labels we recommend that you purchase label sheets (Avery, etc.) where the entire sheet is a single, adhesive-backed label. Once printed you can then use a paper cutter or scissors to cut out the individual barcodes.

    If you have a large number of barcodes to print you might consider buying a purpose-build program like iBarcoder for PC and MAC; or buying labels in bulk from a label printer like ImageTek; or plastic cards from Plastic Printers. Note: there are many excellent label printers globally – ideally look for ones that can print variable data QR codes as they are the best for scanning.

    Developers can use an API call to insert barcode values singularly or in bulk to databases on our servers and then use another API call to generate a QR code to display each value in electronic media, such as email, messaging and web pages.
