Methods and systems are provided for processing secure transactions. An electromagnetic transmission packet is received from a portable device at a processing device. The electromagnetic transmission packet includes an encrypted magnetic-stripe image and an encrypted version of an alphanumerical identifier. A keyed nonencrypted version of the alphanumerical identifier is received at the processing device, and the encrypted version of the alphanumerical identifier is decrypted. The decryption of the encrypted version of the alphanumerical identifier is compared with the nonencrypted version of the alphanumerical identifier. Thereafter, a decryption of the encrypted magnetic-stripe image is transmitted to a host system for processing the secure transaction using an account identified by the decryption of the magnetic-stripe image.

L'invention concerne des procédés et des systèmes de traitement de transactions sécurisées. Un paquet de transmission électromagnétique est reçu en provenance d'un appareil portable au niveau d'un dispositif de traitement. Le paquet de transmission électromagnétique contient une image à bande magnétique codée et une version codée d'un identifiant alphanumérique. Une version non-codée à clé de l'identifiant alphanumérique est reçue au niveau du dispositif de traitement, et la version codée de l'identifiant alphanumérique est décodée. Le décodage de la version codée de l'identifiant alphanumérique est comparée à la version non-codée de l'identifiant alphanumérique. Ensuite, un décodage de l'image à bande magnétique codée est transmise à un système hôte pour le traitement de la transaction sécurisée au moyen d'un compte identifié par le décodage de l'image à bande magnétique.
