Bluetooth is a wireless technology standard for exchanging data over short distances using short-wavelength radio transmissions in the ISM band from 2400–2480 MHz from fixed and mobile devices, creating personal area networks (PANs) with high levels of security. In short, a Bluetooth connection allows a card payment terminal to be portable. With a range of up to 100m from a fixed base unit, the terminal can be moved around, whilst the base unit still maintains a secure and reliable telephone or broadband line from a fixed point. This is the perfect solution for businesses that wish to use a fixed connection but benefit from the flexibility of portable terminals that can be passed over to customers and taken to tables in restaurants and bars.
