A card dispenser (10, 20) comprising: a card store configured to hold a stack of cards; a card feed mechanism configured to move a card in a horizontal direction from the card store to a read position and to dispense said card from the read position by further movement of the card in the horizontal direction; a communication module arranged to read data from a card provided at the read position; a capture chamber configured to receive a card dispensed from the read position by the card feed mechanism, the capture chamber comprising walls defining an exit aperture for dispensing a card to a user; a capture flap (5, 25, 45) provided within the capture chamber, wherein said capture flap is moveable from a first orientation to a second orientation, wherein in the second orientation the capture flap is arranged to guide a card through said exit aperture, wherein said capture flap comprises a floor member along which a card may slide when the capture flap is orientated at the second orientation, wherein said floor member makes a first non-zero angle with the horizontal when the capture flap is at the first orientation, and wherein said floor member makes a second non-zero angle with the horizontal when the capture flap is at the second orientation, wherein said second angle is smaller than the first angle; a card bin configured to receive a card from the capture chamber when the capture flap is arranged at the first orientation, wherein in the first orientation the capture flap provides a path from the read position to the card bin; and a control system for controlling movement of the capture flap in accordance with an output received from the communication module based on reading data from a card at the read position such that if a first output is received indicating that data stored on the card has not been correctly encoded to the card, the capture flap is held at the first orientation such that the card dispensed from the read position moves under the influence of gravity through the capture chamber into the card bin; characterised in that said capture flap is biased towards the first orientation, wherein at the first orientation the capture flap fully closes the exit aperture, and if a second output is received indicating that data stored on the card has been correctly encoded onto the card, the capture flap is moved from the first orientation to the second orientation such that a card dispensed from the read position slides along the capture flap under the influence of gravity through the exit aperture, and wherein said movement of the capture flap from the first orientation to the second orientation opens the exit aperture and closes said path to the card bin. a card store configured to hold a stack of cards;
