2 * RFID support for Koha
4 * Writtern by Dobrica Pavlinusic <dpavlin@rot13.org> under GPL v2 or later
6 * This provides example how to intergrate JSONP interface from
8 * scripts/RFID-JSONP-server.pl
10 * to provide overlay for tags in range and emulate form fill for Koha Library System
11 * which allows check-in and checkout-operations without touching html interface
13 * You will have to inject remote javascript in Koha intranetuserjs using:
15 // inject JavaScript RFID support
16 $.getScript('http://localhost:9000/examples/koha-rfid.js');
