1. Recopier ce module

2. Ajouter dans la base :
    - ps_configuration (14 = id dans ps_order_state_lang): nouvel_id 	NULL	NULL	PS_OS_CARTE 	14	0000-00-00 00:00:00 	0000-00-00 00:00:00
    - ps_order_state_lang: 14 	1 	En attente du paiement par carte 	carte
    - ps_order_state: 14 	0 	1 	carte 	RoyalBlue 	1 	0 	0 	0 	0 	0 	0

3. Remplacer les PS_OS_CARTE à chaque fois qu'il apparait dans le module.
4. Surcharger la classe PaymentModule dans override/classes/PaymentModule.php (pour prendre en compte cette modification, ne pas oublier d'effacer le fichier cache/class_index.php -> il se regénèrera)
