K3 F

The third generation of Custom's fiscal products

K3F starts the third generation of Custom's fiscal products. With an ever more advanced and specialized technology, K3F not only improves speed and reliability performances, but also opens the doors to mobile communication with its Ethernet interface (standard equipment) and Wi-Fi connectivity (optional). These features have been conceived to use the product with applications designed for mobile and cloud-oriented sales. K3F has no technological limits: it can be managed via LAN or via a geographic network and it can be easily reached by any device, like tablets or smartphones with network access.
