A mobile payment device 130 provides a trusted code base which obtains a password from a customer for processing a payment transaction and encrypts the password using a public key. Access to the trusted code base by unauthorized processes is prevented to protect the password while unencrypted. The mobile payment device 130 transmits the encrypted password over a network 140 to a transaction host 160. The transaction host 160 decrypts the encrypted password and applies the decrypted password to process the payment transaction.
