How to Make a Quick Response Code (NYT Personal Tech)

I want to call readers’ attention to the fine information available via NY Times Personal Tech Q&A.

Here http://tech.nytimes.com/pages/technology/personaltech/index.html is a link to this section of their website.

Consider signing up for their weekly Personal Tech email.

Below is an example of what you’ll find.

Q. How can I make a QR code pointing to my personal Web site that I can attach to an e-mail signature?

A. Several Web sites will convert a standard URL into a Quick Response (QR) code. Once converted, the image can be attached to an e-mail signature, uploaded as a Facebook profile photo, printed out or posted elsewhere online. Some QR-conversion sites can also encode maps, text, phone numbers or RSS feeds.

These sites include Kaywa (qrcode.kaywa.com), Qurify (qurify.com/en) and Delivr (delivr.com/qr-code-generator). The Google URL Shortener (goo.gl) will also create a QR code file from a shortened link — just click Details to see the image file.

Quick Response codes are basically two-dimensional bar codes that can be interpreted by a cellphone camera equipped with a code-reading app. Once the code is scanned, for instance, the Web address embedded in the image pops up on the phone’s browser, saving the user some typing.

See? I told you they had good content. Each week they have several of these questions as a column.
