Hello, I know that QR code is an interesting topic because the QR code is the later version of the bar code, and it has multi-purposes of usages. Since the applications of QR codes are vast, it’s easy to loose the focus when talking about them. You did well in explaining what the QR codes are and how they are used. However, what you lack of are the reasons that QR codes are used widely in the industry and other fields. I’m sure that having those information will attract your readers.
ReplyDeleteHi Vimal,
ReplyDeleteFirst I would like to thanks for commenting on my blog. Second, I really like your QR code, which posted on the top right. It looks really cool with black and white pattern effect. In this post, I agree with you that scanning QR code by using smartphone might get some security issues. Most of malicious QR codes we see on the street are not safe to scan. Scammers are currently using these codes to lure people to their traps. However, most people scan the QR code because they are curious about these little black and white decoded squares. Who isn't right? When scanning fake QR codes, they easily get attacked because of installing a application to their PC, or input required personal information from the visiting website.
Your post is very informative. The only thing that I would like to suggest that your post have some typing errors, which are very easy to see when copy and paste to a word editor like MS Word.
