Abstract

L'objectif de la présente invention est de permettre de préserver les performances de lecture d'informations magnétiques d'un dispositif de traitement de carte tout en réduisant la lecture illicite d'informations magnétiques à partir d'une carte magnétique. La présente invention concerne un dispositif de traitement de carte, comprenant : un trajet de transport de carte sur lequel une carte magnétique est transportée depuis son insertion dans une ouverture d'insertion de carte jusuq'à son éjection de l'ouverture d'insertion de carte ; des première et seconde unités d'émission de champ magnétique qui émettent respectivement des champs magnétiques de brouillage à proximité de l'ouverture d'insertion de carte ; et une unité de commande qui commande le fonctionnement des première et seconde unités d'émission de champ magnétique. Pendant que la première unité d'émission de champ magnétique et la seconde unité d'émission de champ magnétique émettent les champs magnétiques de brouillage, si une opération prescrite doit être effectuée par rapport à la carte magnétique sur le trajet de transport de carte, l'unité de commande amène la première unité d'émission de champ magnétique à entretenir l'émission du champ magnétique de brouillage et amène la seconde unité d'émission de champ magnétique à suspendre le champ magnétique de brouillage.
