Readers need to find a self-service lending and returning machine in the service desk or lobby of the library, which is generally marked with the words "self-service lending and returning".

Readers need to ensure that their reader ID cards (usually magnetic cards or paper cards with bar codes) are valid and registered. If readers don't have a reader's card, they need to go to the service desk.

According to the prompts on the self-service book borrowing machine, put the reader card in the sensing area on the machine, or scan the bar code on the reader card. At this point, the machine will read the reader's information, and display the reader's name, borrowing quantity, borrowing period and so on.

Readers need to choose the books to borrow and input the book number or title into the machine. The machine will display the information of the book, including the title, author, publishing house, status in the library and so on.

If the book is displayed as "loanable" in the library, the reader can click the "Lend" button to borrow it. At this point, the machine will print out a book borrowing voucher and prompt the reader to take away the book and voucher.

Readers need to check whether the information on the borrowing voucher is correct, including the borrowed book information, borrowing period, etc. If there are any mistakes, you need to contact the staff to correct them in time.

Finally, readers need to keep the borrowing voucher as a voucher when returning books.

It should be noted that the operation steps of the self-service borrowing machines in various libraries may be slightly different, but the general process is the same. In addition, readers should pay attention to protecting personal privacy and information security when using the self-service book borrowing machine, and do not disclose important information such as passwords to others. At the same time, if you encounter any problems or failures, you need to contact the library staff in time to deal with them.

Generally speaking, it is a convenient and quick way to borrow books by using the library self-service borrowing machine, which can greatly improve readers' borrowing efficiency and experience. At the same time, it can also reduce the workload of library staff and improve the service quality and efficiency of the library.
