A system to write information on a display of a card, the card including: a first longitudinal side, and a second longitudinal side opposite to the first longitudinal side, the display being between the first and second longitudinal sides (108, 110), the system comprising a writing system, the writing system including: a first slot for receiving the first longitudinal side of the card, the first slot being formed between two first opposing slot members (120a1, 120a2), and a second slot for receiving the second longitudinal side of the card, the second slot being formed between two second opposing slot members (120b1, 120b2), an actuation mechanism for actuating the first slot and the second slot by imparting movement on at least one of the respective opposing slot members so as to respectively constrain the first and the second longitudinal card sides (108, 110), constrainment being implemented by effecting a reduced slot width, the writing system further comprising a transparent volume formed between the first and the second slot (118a, 118b) so that the display is externally viewable while the first and the second longitudinal card sides (108, 110) are constrained at the first and second slot (118a, 118b) and an imager to operate the display in an area opposite to the transparent volume while the first and the second longitudinal card sides (108, 110) are constrained by the first and second slots (118a, 118b), the imager being external from the display, the display including passive electronic paper, and the imager including a writing device to operate the passive electronic paper passing in relation to said writing device. a first longitudinal side, and a second longitudinal side opposite to the first longitudinal side, the display being between the first and second longitudinal sides (108, 110), the system comprising a writing system, the writing system including: a first slot for receiving the first longitudinal side of the card, the first slot being formed between two first opposing slot members (120a1, 120a2), and a second slot for receiving the second longitudinal side of the card, the second slot being formed between two second opposing slot members (120b1, 120b2), a first slot for receiving the first longitudinal side of the card, the first slot being formed between two first opposing slot members (120a1, 120a2), and a second slot for receiving the second longitudinal side of the card, the second slot being formed between two second opposing slot members (120b1, 120b2), an actuation mechanism for actuating the first slot and the second slot by imparting movement on at least one of the respective opposing slot members so as to respectively constrain the first and the second longitudinal card sides (108, 110), constrainment being implemented by effecting a reduced slot width, the writing system further comprising a transparent volume formed between the first and the second slot (118a, 118b) so that the display is externally viewable while the first and the second longitudinal card sides (108, 110) are constrained at the first and second slot (118a, 118b) and an imager to operate the display in an area opposite to the transparent volume while the first and the second longitudinal card sides (108, 110) are constrained by the first and second slots (118a, 118b), the imager being external from the display, the display including passive electronic paper, and the imager including a writing device to operate the passive electronic paper passing in relation to said writing device.
