QR has been around since 1994. Print one at roughly a tenth of its scanning distance and leave the quiet zone clear.
What is Online QR Code Generator?
QR Code Generator is a free online tool for generating QR codes. QR Code stands for "Quick Response Code". QR Code is a 2-Dimentional barcode first used in 1994 originated from Japanese automotive industry. Its popularity within other barcode types is its high capacity for storing data. You can store any text-type data in QR Codes, but it is generally used for storing links recently.
Although there are many usage areas of QR Codes, it is mostly used for giving links to websites and mobile applications on Google Play and Apple Store. Other than that, you can use them to create vCard's (Contact Cards on Mobile), sending e-mails, making, or getting payment etc.
QR Codes can be scanned by smartphones either natively or by using 3rd party apps. You can search mobile markets if you need a QR Code Scanner.

Frequently asked questions
What can a QR code hold?
A URL most often, but also plain text, an email address, a phone number or contact details. A URL is usually the better choice even for other content, because you can change what sits behind it later.
Does a QR code expire?
The code itself never does — it is a picture of some data, and it will scan in ten years. What expires is whatever it points at. A code printed on packaging outlives most URLs, which is the usual way these end up broken.
How small can I print one?
As a rule of thumb, about a tenth of the scanning distance — a code read from a metre away wants to be around 10cm. Leave the quiet zone of clear space around it too; codes printed hard against other artwork often fail to scan.
Why will my code not scan?
Usually too small, too little contrast, or no quiet zone. Inverted colours are another common cause — most scanners expect dark on light, not the reverse.
Does a longer URL make a denser code?
Yes. More data means more modules, which means a code that needs to be printed larger to stay readable. Shortening the URL first is the simplest fix.
What about traditional barcodes?
The Barcode Generator covers the one-dimensional formats used in retail and logistics.
