the QR Codes created by QRickit have an expiration date or time
No. The QR Codes generated using the QRickit
QR Code Creators, QRickit
API and QRickit Widget do
not have time expirations or limits on them. The QRickit QR Code image is simply
a graphical representation of whatever data you entered. A QR Code reader app
installed on a handheld device (i.e. smartphone or tablet) is then used to scan
and translate the image back to its original data. *QRickit does not modify your
original data when generating QR Codes.
Some "QR Code" companies charge you a monthly/annual fee to use their "QR Codes" although QR Codes are free to make and use forever. These companies are, in fact, charging you to use their own URLs and the tracking (i.e. statistics) and management (i.e. redirection) of those URLs. They have so-called expiration dates because they want you to continue paying for using their service. It is not the expiration of the QR Code, but the expiration of your service. These companies can be convenient for most people.
is the error correction level of the QR Codes created by
QRickit? (This is for technical minds)
The default error correction level is set to medium (i.e. parameter e = M)..
L = Low (7% error correction)
M = Medium (15% error correction)
Q = Quartile (25% error correction)
H = High (30% error correction)
The "error correction level" or "e" parameter means that the QR Code can still be readable even if it is damaged (or hidden/covered). So if you set the "e" to L (Low 7%) the QR Code will still be readable if 7% of it is damaged. If you set the "e" parameter to H (High 30%) that means you can cover (i.e. damage/hide) about 30% of the QR Code and it would still be readable. However, the higher the "e" the less data the QR Code can store. If you have a lot of data, then you may have to set the "e" to Low for your QR Code to work. If you have only a little data, then you can set the "e" to High. The QRickit QR Code Creators are by default set to an error correction of 15% (Medium) which is sufficient for most cases.
* Only the QRickit QR Code Creator for URL is set to a default error correction of 30% (High) since some people like to customize this type of QR Code with their logo or other design. Theoretically, you can cover (not the corners though) up to 30% of the QR Code with your own logo/image and it will still be readable.
I change the QR Code or its data later?
The QRickit QR Code image is simply a graphical
representation of whatever data you entered. If your data changes then you need
to create a new QR Code.
* About URL Redirection (i.e. your URL data changes and you do not want to create/use a new QR Code)
You can use auto redirect (i.e. URL forwarding). Ask your URL/web provider to set this for you. Or you can put 1 line of HTML code in your webpage to automatically redirect to another URL.
Here is the line of HTML code you put in the <HEAD> section of your web
page to make it automatically redirect to another URL:
do I make a custom QR Code?
You can cutomize the size, color, background color, and footer text when using the QRickit QR Code Creators..
If you want to add a logo/image or further modify the QR Code image, first download a high res version of it. Then you can use almost any graphic editing software (i.e. Photoshop)
to change the colors or add small things on top of or around the
QR Code. If you (or your graphic designer) are fairly creative,
you can even come up with ways to place the QR Code inside your
logo or image instead of the other way around! Just make sure
you test your final image with your mobile phone to see if the
QR Code still works after your changes.
When creating a QR Code, it should be set with a high error correction rate (i.e. the "e" parameter). A higher "e" parameter means that the QR Code can still be readable if a higher percentage of it is damaged (or hidden/covered). So if you set the "e" parameter to 30% (the max) that means you can cover (i.e. destroy) about 30% of the QR Code with your logo/image on top and it could still be readable. The QRickit QR Code Creator for URL is by default set to an error correction of 30% (High). Work on a trial and error basis and always keep testing your QR Code to see if it still can be read whenever you modify it. You should also not cover or alter the 4 corners (i.e. the "eyes"). Customization works best when the QR Code data is very short/small, such as a URL (a shortened URL is even better).
