What are Quick Response Codes?

QR codes are a type of barcode which can be read using a mobile device's camera with the appropriate software installed.

QR codes can contain different kinds of information such as web links/URLs, phone numbers, videos, others pieces of textual information, or even a combination of these. (example: scanning the code on the left will open up the website shown on the right)

If you scan a QR code that contains a URL link and your mobile device has internet access, you can use your devices´s browser to open the link. Alternatively you can save the information and use it later – it will at least save you having to write it down at the time. Other kinds of information can also be saved for later.

Using QR Codes in the Library

Group Work Room Booking

There are QR codes posted on the doors of each Bookable Group Work Room in the Library. These QR codes link directly to the booking calender for their respective rooms, and make it possible to book a room in seconds as you are walking into it. You will have to log into your U of L account the first time you book a room using the QR codes, but you can save your credentials on your phone for future use. Bookings can also be made from our website or by visiting a service point in the library.

A poster like the one seen in the image above is posted the door of every BOOKABLE group work room in the LIbrary. Bookable group work rooms are available on level 10 and level 11 in the library. 

Other places you might see QR codes.

The Library uses QR codes in pamphlets, on posters, on notice boards, and on other printed items to link you to online feeds, help guides, directories, and connect you with our help desk. Wherever you see the Ask US QR code, you can quickly scan it to send the help desk a text, or talk to them on the phone.
