[Koha] To count users in the library rooms

Hi to all, in our library we want to count persons there are in the rooms. I think to read the library card when a user goes in and when he goes out. The library car has a unique barcode. I'm plannig to use Koha as DB of users. Do you know any open source solution about this request ? Do anyone develop something on Koha about it ? Bye Zeno Tajoli -- Dott.
