K10 is one of the first cash registers to combine the features of a desktop and a mobile unit. The cordless system can connect with other devices via Bluetooth and has a hands-free function. The touchscreen interface is adjustable to the user’s individual needs. On the exterior, the casing is coated in non-slip elastomer, which has a pleasant feel and is moisture-repellent. The interior consists of hard ABS plastic to protect the device from damage if dropped.
