A retail system includes a printed display (12), for example shelf edging or display stand, an electronic basket (13), which may take the form of a module attached to a physical basket or trolley (14) or a mobile device, and a checkout module (15). The printed display comprises a processor (27) memory (28) storing data (30) identifying a product (4), a capacitive touch switch (23) coupled to the processor and a wireless interface (29), for example a Bluetooth wireless interface. The display processor is configured, in response to user actuation of the capacitive touch switch, to cause the wireless interface to transmit the data. The electronic basket comprises a processor (36), memory (37) and a wireless interface (38). The basket processor is configured to transmit the data. The checkout module comprises a processor (44), memory (45), a wireless interface (46) and a network interface (41). The checkout module processor is configured, in response to receiving the data via the wireless interface, to transmit a request to retrieve the product. |
