As everyone know, the library is where we often go to read books, but with the continuous development of the retail economy, bookstores are becoming an important place for people to gain knowledge. People prefer to read slowly and treasure this book. Bookstores generally only sell books, unlike libraries that need to return books. Therefore, the clerk only needs to take measures to prevent theft of books. The anti-theft label required for the book is flat. Emeno recommends using a radio frequency soft label to be attached to the back of the book with outer packaging. It is matched with Emeno RF6818 acrylic antenna. After the customer purchases the book, the shop assistant uses a specially configured radiofrequency decoder board. After unlocking the anti-theft, you do not need to remove the label to complete the book purchase.
