How to make sure the QR Code image you are scanning is safe
May 22, 2013
There are QR Codes on the bus, magazines, internet. My phone has been infected with virus for three times. So I wonder is there any app with which I can testify the QR Code is safe?

QR code (abbreviated from Quick Response Code) is the trademark for a type of matrix barcode (or two-dimensional barcode) first designed for the automotive industry in Japan; a barcode is an optically machine-readable label that is attached to an item and that records information related to that item: The information encoded by a QR code may be made up of four standardized types ("modes") of data (numeric, alphanumeric, byte / binary, Kanji) or, through supported extensions, virtually any type of data.
Recently, the QR Code system has become popular outside the automotive industry due to its fast readability and greater storage capacity compared to standard UPC barcodes; applications include product tracking, item identification, time tracking, document management, general marketing, and much more.
A QR code consists of black modules (square dots) arranged in a square grid on a white background, which can be read by an imaging device (such as a camera) and processed using Reed-Solomon error correction until the image can be appropriately interpreted; data is then extracted from patterns present in both horizontal and vertical components of the image.
Originally designed for industrial uses, QR codes have become common in consumer advertising. Typically, a smartphone is used as a QR-code scanner, displaying the code and converting it to some useful form (such as a standard URL for a website, thereby obviating the need for a user to type it manually into a web browser).
You can generate and read different kinds of barcode with the help of many professional SDKs:
I'm studying about this recently.
I hope we can have some communication later.

As to scan the qr code barcode image in the best status, we'd better use an excelusive qr code reader.
