With so many free QR code generators you may wander why sould I give 5$ to make me some QR Codes?
Answer: Clasic QR Code generators will give you a black and white code and you do not have a option to place a logo inside.
So if you want to attract more customers dont just use qr codes use one personalised to you.
Check the job I talk about at this link.
Promo if you mention this article you can order 2 codes with the logo inside at tha same amount of money.
