The POS system according to one or more of the preceding claims, wherein the mobile unit (2) or the stationary unit(3) are configured to transmit an ID via a physical contact connection or wireless local area connection which can be NFC., RFID, Zigbee, Bluetooth and/or Bluetooth low energy, in order to then transmit the ID to the management unit (6) via a network, which can be WLAN, Ethernet or Bluetooth.

The POS system according to the previous requirements, wherein the first connection (10) and/or the connection (10.1) is arranged between the mobile units (2), the stationary unit (3), the management unit (6) or the POS peripheral unit (5.1, 5.2, 5.3) as an encrypted connection, and wherein the management unit (6) is preferably configured to transmit keys of an encryption key pair to the mobile unit and/or stationary unit, and can also be configured to generate them.

The POS system according to one or more of the preceding claims, wherein a virtual interface, which can be RS232 or USB, of the POS system application is provided on the mobile unit (2) which is configured to establish a logical connection (X) (Y) to the stationary unit (3) and/or POS peripheral unit (5.1, 5.2, 5.3), and the authentication is carried out via the management unit (6).

The POS system according to one or more of the preceding claims, wherein by the rule set verifies whether the allocation, the ID, the timing, the spatial distance, the user login and/or the category of the POS peripheral unit are allowable in order to grant a connection.

The POS system according to one or more of the preceding claims, wherein the mobile unit (2) is configured to allow an interactive selection of stationary units (3) and/or POS peripheral units (5.1, 5.2, 5.3), and/or wherein a physical interlock is provided to physically to establish a interlock after a physical connection of the stationary unit (3) to the mobile unit (2), wherein the lock being controlled by the management unit (6) according to the rule set.

The POS system according to one or more of the preceding claims, wherein the POS peripheral unit (5.1, 5.2, 5.3) is one or more of the following components:

• an automatic cash safe, a cash drawer, a printer, a keyboard, a scanner, a 3d scanner, a pin pad (over LAN), a card reader, a monitor, a line display, a scale, a NFC reader, a banknote deposit device, a banknote disburse device, a coin deposit device and/or a coin disburse device.

The Method according to the preceding method claim, wherein the management unit (6) receives both a request via the second connection (11) from the mobile unit (2) and in parallel has to receive a request via the third connection (12) from the stationary unit (3) to allow access via the logical connection (X) (Y), and the inquiries should arrive within a defined time window.

The Method according to one or more of the preceding claims, wherein an ID of the mobile unit (2) and/or an ID of the stationary unit (3) are acquired and these are transmitted to the management unit (6) for identification.

The Method according to the preceding claim, wherein the connections between the mobile unit (2), the stationary unit (3), the management unit (6) and/or the POS peripheral unit (5.1, 5.2, 5.3) are encrypted.

The Method according to one or more of the preceding claims, wherein a virtual interface, which can be RS232, USB on the mobile unit (2) is provided to the POS software, which is provided as logical connection (X) (Y) to the stationary unit (3) and/or to the POS peripheral unit (5.1, 5.2, 5.3).

The Method according to one or more of the preceding claims, wherein the rule set is used to check whether the assignment, the ID, the timing, the spatial distance, the user login and/or the category of the POS peripheral unit are allowed.

The Method according to one or more of the preceding claims, wherein a physical interlock is present and an interlocking occurs after a physical connection of the stationary unit (3) to the mobile unit (2) is determined, wherein the interlocking is performed by the management unit (6) according to the rules set.
