The procedure to create a point of sale (POS) register is as follows:
1) First, go to Retail and commerce, enter Channel setup, then POS setup, when you get to Registers, click New.
2) Now create an ID for new register in the Register number field. The register ID would include codes that allow mapping of registers to the stores it belongs and specific locations within the stores.
3) Insert a descriptive name for the register, in the Name field,
4) Now enter or select a value, in the Store number field.
5) Moving to the Hardware profile field, again enter or select a value. Hardware profiles specify the retail peripherals to be connected to the register, like cash drawers and receipt printers.
6) In the Visual profile field, again you would be required to enter or select a value. Visual profiles specify the images utilized in the POS background and login page including themes for the POS.
7) Moving to the EFT POS register number field, insert a value. The EFT POS register number effectively informs the payment processor of the payment terminals sending authorization requests. 8) This value generally found on a sticker attached to the payment device is called the "Terminal ID" or “TID”. Now click Save.
