The POS Tower 100 is a self-checkout system at which the customer can execute the complete checkout process on his/her own without the need for an assisting cashier. At the systems the customer scans the item him-/herself, puts the scanned items onto the adjoining weight platform – if available directly into provided bags – and pays the purchase either with cash or by card directly at the system. The POS Tower 100 is available as a flexible bag and DIY store solution.
