Abstract
An indicator device comprises a first slide member (22) mounted on a planar base (1). The first slide member (22) is displaceable between a first position in which it reveals a first status indicating area (26) indicative of a first condition or state and a second position in which it reveals a second status indicating area (28) indicative of a second condition or state. A second slide member (30) is mounted on the base (10) and is displaceable into and across the path of the first indicator member (22) when the first indicator member is in the first position, to inhibit displacement of the first indicator member. The second indicator member (30) is displaceable between a first position in which it does not inhibit the displacement of the first indicator member (22) and a second position in which it inhibits the displacement of the first indicator member to its second position. The device may also be provided with one or more RFID tags (80, 82, 84) to permit remote monitoring of the status of the device. The device can be used, for example, in conjunction with a dispenser (60) to provide an indication of when stock needs to be reordered and whether reordering of the stock has taken place.
