I'm using this script to generate QR codes for all the PyCon India 2014 attendees' names and ticket id

generate_qrcodes.py

import csv
import qrcode
from PIL import Image, ImageFont, ImageDraw

attendees = []

with open('completed_attendees.csv') as userlist:
    userreader = csv.reader(userlist, delimiter=',')
    for row in userreader:
        attendees.append({
            'ticket': row[0],
            'name': row[1]
        })

font = ImageFont.truetype('ubuntu.ttf', 30)
qr = qrcode.QRCode(
    version=1,
    error_correction=qrcode.constants.ERROR_CORRECT_L,
    box_size=6,
    border=0,
)

for at in attendees:
    backimg = Image.open('back.png')
    qr = qrcode.QRCode(
        version=1,
        error_correction=qrcode.constants.ERROR_CORRECT_L,
        box_size=6,
        border=0,
    )

    qr.add_data(','.join([at['name'], at['ticket']]))
    qr.make(fit=True)
    qrimg = qr.make_image()
    qrimg = qrimg.resize((210, 210))

    backimg.paste(qrimg, (20, 20))
    draw = ImageDraw.Draw(backimg)

    # Just to check the images for people with longest names
    if len(at['name']) > 25:
        print at

    draw.text((250, 20), at['name'], font=font, fill=(0, 0, 0))
    draw.text((250, 60), 'Ticket ID: {}'.format(at['ticket']), font=font, fill=(0, 0, 0))
    draw.text((290, 200), '_____________________________', font=font, fill=(0, 0, 0))

    backimg.save('new/{}.png'.format(at['ticket']))
