At the beginning we choose the library - the libraries we use and then ...
it is enough to scan (or more precisely, photograph) the book's barcode with the phone's camera to get full information about the volumes of the series or other items written by the author. In the case of a series (cycle), let's additionally find out whether the individual volumes are to be read in the right order or not - we read freely. The application works with both the library code and the ISBN code printed on the book. A scan of the code from the book (new) in the bookstore will tell us which institution already has it in its collection. The information is supplemented with a map with the selected facility and its opening hours.
The application allows you to store library cards in QRCode formats, as well as quick access to library accounts (prolongation of items, information on return dates, etc.). There is no limit to the number of supported cards or library accounts - you can store the cards of the whole family and easily select them while at the counter (renting items).
