Abstract
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.
