The tablet computer can run a merchant application to provide the typical functionality for a point-of-sale system. The stand can be rotatable to face either the merchant or the customer. The stand can incorporate a card reader. The tablet computer can be connected through a hub to other peripheral components, such as a controllable cash drawer, a printer and/or a bar code reader. The cash drawer can include a slidable drawer having sliding rails that are hidden from a top view of the drawer. ## Claims ### Claim 1 A cash drawer for a point of sale system, comprising: a slidable drawer including a front face, a back face, a first side face, a second side face, and a bottom face, an inner shell attached to the first side face, the second side face, the front face, the back face, and the bottom face, and two sliding rails, the two sliding rails positioned under the inner shell and extending parallel to the first and second side faces; a drawer enclosure having two rail supports to slidably support the rails such that the drawer is slidable between a closed position and an open position and a closed position; a latch movable between a first position in which the latch holds the slidable drawer in the closed position and an open position; and an actuator configured solenoid move the latch from the first position to the open position. ### Claim 2 (depends on 1) The cash drawer of claim 1, wherein the actuator comprises a solenoid. ### Claim 3 (depends on 1) The cash drawer of claim 1, comprising a catch that couples the drawer to the drawer enclosure. ### Claim 4 (depends on 1) The cash drawer of claim 1, where the inner shell is formed to support a tray within the drawer. ### Claim 5 (depends on 1) The cash drawer of claim 1, where the drawer enclosure comprises an opening and a fastener, wherein the opening is configured to receive a mating feature of a stand and wherein a trigger of the fastener locks the stand enclosure in place. ### Claim 6 (depends on 5) The cash drawer of claim 5, where the opening is formed to include a plug, and where the triggering of the fastener releases the plug. ### Claim 7 (depends on 5) The cash drawer of claim 5, wherein the opening includes a data port configured to mate to a data port of the stand. ### Claim 8 (depends on 1) The cash drawer of claim 1, wherein one of the two sliding rails is attached to the first side face and another of the two sliding rails is coupled to the second side face. ### Claim 9 (depends on 1) The cash drawer of claim 1, wherein the latch comprises a first piece, a second piece, a first spring configured to urge the first piece to rotate in a first direction, and a second spring configure to urge the second piece to rotate in a second direction opposite the first direction. ### Claim 10 (depends on 9) The cash drawer of claim 9, wherein in the closed position a pin attached to the slidable drawer fits into a slot in the first piece and the second piece is position to prevent the first piece from rotation such that an edge of the slot prevents forward motion of the pin. ### Claim 11 (depends on 1) The cash drawer of claim 1, wherein in the closed position a back surface of the front face of the slidable drawer bears directly against a front surface of the drawer enclosure. ### Claim 12 A cash drawer for a point of sale system, comprising: a slidable drawer including a front face, a back face, a first side face, a second side face, and a bottom face, and two sliding rails; a drawer enclosure having two rail supports to slidably support the rails such that the drawer is slidable between a closed position and an open position and a closed position, wherein in the closed position a back surface of the front face of the slidable drawer bears directly against a front surface of the drawer enclosure; a latch movable between a first position in which the latch holds the slidable drawer in the closed position and an open position; and an actuator configured solenoid move the latch from the first position to the open position.
