during my search i found that following Types are valid to generate Bar/QR code in Qweb PDF

'Codabar', 'Code11', 'Code128', 'EAN13', 'EAN8', 'Extended39', 'Extended93', 'FIM', 'I2of5', 'MSI', 'POSTNET', 'QR', 'Standard39', 'Standard93', 'UPCA', 'USPS_4State'

how i know which one is perfect for the requirement? recently in my testing, i used Code128 but it some times work and some times not. like on page 1 record 1 it is showing data correctly but when scanning through mobile app but on 2nd it is showing wrong data, which leads me to use another Type but please help to understand which Type? please note, i am using 2 fields data to generate barcode like below (thanks to @Cybrosys Tech for help):

img t-attf-src="/report/barcode/Code128/{{o.name}}{{o.ref}}" style="width:200px;height:50px" alt="Barcode"

all odoo data types are applicable to generate Bar/QR code?

i want to generate Bar/QR code with combination of fields like: name, price, expirty date etc.

regards
