Oltre.app (by Oltremare, a brand of Zucchetti Axess - www.oltremare.net) offers both data collection and interaction with the Oltre suite (Time&Attendance, Access Control, Patrol Route Control, Job Costing, Rostering, Fixed and Mobile Devices Handling).
It is available both for tablets and smart-phones.
As a data collector it can act as a terminal (reading the badge identifier) and as a badge as well (reading the terminal identifier or the identifier of a location) by means of NFC, barcode, QRcode (or keyboard) and georeferencing. The off-line mode is also supported.
