Hi cindy
Thanks for your nice sharing.As QR Code has a wide valid data scope, thus, people often encode a website link into QR Code. Then one can easily visit this website by just scanning the QR code barcode, instead of entering the url in the web browser. Therefore, QR Code has been widely used in the marketing and advertising field as a promotion tool. So i want to know that if you know any free trial from qr code barcode generater.Thanks a lot.
