QR code for EZID


A QR code is a type of two-dimensional barcode that can be scanned by many mobile phone cameras.  In EZID the QR code can be thought of as a kind of persistent graphical hyperlink. Uses include automatically reading a web address from a printed page or offline display into a mobile phone’s browser.   Simply right click on the code to copy the image and use it anywhere you’d like.

If you’d like to test this new function, go to EZID’s Help tab. You’ll see there that you can make test DOIs and test ARKs without an EZID account. Just click Create. Once you do, you’ll be on the Manage tab where you will see the QR code for the new identifier. For information about getting an EZID account, contact us.

Please feel free to post comments here and let us know how you are using the codes.
