Creating barcode images

votes

I need to send emails out to several thousand customers with a unique barcode present so they can redeem it either instore or online.

We have a list of coupon/barcode codes to use and have a way to dynamically pull these codes into the email so a customer will see a unique code. The problem is I need to somehow generate several thousand barcode images that are created using the unique codes. How can I solve this?

This would be perfect if our email marketing company had this functionality but unfortunately they don't: http://www.emaildirect.com/blog/2011/11/create-unique-barcodes-with-emaildirect/

Any help would be greatly appreciated.

I have found my answer!

By using the barcode generator www.barcodesinc.com I generated a URL and input this into my email.

Eg: http://www.barcodesinc.com/generator/image.php?code=999999999&style=197&type=C128B&width=200&height=50&xres=1&font=3

I then changed the 999999999 in the URL to my conditional code to change to the specific code for that person and also bring back the barcode image for that code too!

Does your application require QR Code? What is the format of your data? - Brian Anderson
No I don't think a QR code is required. Just the barcode as this will be scanned in stores or redeemed online using the barcode number present underneath. - Damodog

I'm no expert on this and haven't touched html but you could serialize each image and follow this example that has some sample code on QR code given a string.

Imports ThoughtWorks.QRCode.Codec

Dim objQRCode As QRCodeEncoder = New QRCodeEncoder()
    Dim imgImage As Image
    Dim objBitmap As Bitmap

    objQRCode.QRCodeEncodeMode = QRCodeEncoder.ENCODE_MODE.BYTE
    objQRCode.QRCodeScale = 2
    objQRCode.QRCodeVersion = 5
    objQRCode.QRCodeErrorCorrect = ThoughtWorks.QRCode.Codec.QRCodeEncoder.ERROR_CORRECTION.L
    imgImage = objQRCode.Encode("Test Data")
    objBitmap = New Bitmap(imgImage)
    objBitmap.Save("C:\QRCode.jpg")

Hi Try getting in touch with http://www.linktagger.com and ask if they can help. They provide Enterprise type services for the city where I live on maps and bus terminals so it might help you.

Here is an working example to generate barcode for the array of barcodes.We can retrieve thousands of barcodes from csv file using pandas as well. This example calls API and save the response in image(.png format) obtained as response from API call.

import shutil

import requests

data = [11111111111, 22222222222222222, 33333333333333, 4444444444444]

url = 'https://www.barcodesinc.com/generator_files/' + 'image.php?'

for d in data: params = {

    'code': d,
    'style': '197',
    'type': 'C128B',
    'width': '200',
    'height': '50',
    'xres': '1',
    'font': '3',
}
    response = requests.get(url, params, stream=True)
    with open('image-%s.png' % d, 'wb') as out_file:
        shutil.copyfileobj(response.raw, out_file)
    del response
