[@Double] Since my character while employed at D-Connect was responsible for programming cards and Digimon do you wish to put a restraint on her ability to do such things? She wouldn't be able to it on the fly in the field, that requires a computer with the right software and blank cards or reprogramming an existing card. What does the Digivice look like? EDIT: Now that I think about it could be done on a tablet or smartphone with a card reader. Though it would still take time and couldn't be done in the heat of battle.
