KELLER — Book tracking will soon become faster and more efficient at the Keller Public Library.City Council approved a proposal Oct. 15 for the purchase and installation of radio-frequency identification technology, known as RFID.Jana Prock, library director, said the new technology will allow items to tracked and communicated through radio waves.The system includes a “smart book drop” with five bin sorters, tags, scanners, software license, upgrades to the current self checkout system and a mobile staff station for tagging the collection.“The customer service and convenience issue is one of the best features of the RFID,” Prock said. “Books are instantly checked in, patron accounts immediately reflect the items returned and the materials are immediately shown as available once scanned. This improves the efficiency of the self checkout process.”Prock said the library currently sorts, shelves and checks out more than 560,000 materials per year.“The RFID sorter automatically checks in books, sorts books by type and places them into designated bins,” she said. “This reduces check-in and shelving time and allows more time for interaction between the library staff and patrons.”The Keller Public Library is using an inter-local agreement with the city of Fort Worth to purchase the system, which will cost $141,070 including training.The Friends of the Keller Library, a non-profit organization that supports the Keller library by raising money through book sales, will donate $30,000.The special revenue fund, donations from citizens through water bills, will pay $105,820. Another $5,250 will come from the library’s budget.Councilman John Hoffmann said the purchase will be a great advancement for the library.
