1. A portable device, comprising:
- one or more processors;
a first wireless interface;
a second wireless interface;
a non-transitory computer readable medium comprising executable instructions that, when executed by the one or more processors, cause the one or more processors to perform the steps of;
receiving, via said first wireless interface, an account information request signal from a merchant machine;
transmitting, via said first wireless interface, a response message to said merchant machine, said response message comprising said account information for said merchant machine;
encrypting a first message using a first encryption key, said first message comprising a requesting to get information about a financial account configured in said portable device;
mapping, by a packet filter, said encrypted first message to a pre-established non-GBR bearer;
generating a fourth message by encrypting said encrypted first message for an additional time employing a third encryption key;
transmitting on said non-GBR bearer, via said second wireless interface, said fourth message on a first plurality of subcarriers of an OFDM wireless network;
receiving on said pre-established non-GBR bearer, via said second wireless interface, a second encrypted message on a second plurality of subcarriers of said OFDM wireless network;
decrypting said second encrypted message using a fourth decryption key, said second encrypted message comprising said financial account information;
decrypting said decrypted second message using a second decryption key, and store said financial account information; and
sending to a display at least a portion of said financial account information.

Abstract
A portable device transmits a payment card number to a merchant machine. The portable device generates an encrypted first message comprising a request to get information about a financial transaction. A packet filter maps the encrypted first message to a pre-established non-GBR bearer. The portable device generates a fourth message by encrypting the encrypted first message and transmits the fourth message. The portable device receives and decrypts a second encrypted message. The portable device decrypts the decrypted second message and sends financial transaction information to a display.

9. A portable device, comprising:
-
one or more processors; a first wireless interface; a second wireless interface; a non-transitory computer readable medium comprising executable instructions that, when executed by the one or more processors, cause the one or more processors to perform the steps of; receiving, via said first wireless interface, a request signal from a merchant machine; transmitting, via said first wireless interface, a response message to said merchant machine, said response message comprising a payment card number for said merchant machine; receiving a certificate from an account server subsequent to transmitting said response message; verifying the certificate from the account server; generating an encrypted first message, subsequent to verifying said certificate, by encrypting a first message using a first encryption key and by adding at least one packet header, said first message comprising a request to get information about a financial transaction of said payment card; mapping, by a packet filter, said encrypted first message to a pre-established non-GBR bearer; generating a fourth message by encrypting said encrypted first message for an additional time employing a third encryption key; transmitting on said non-GBR bearer, via said second wireless interface, said fourth message on a first plurality of subcarriers of an OFDM wireless network; receiving on said pre-established non-GBR bearer, via said second wireless interface, a second encrypted message on a second plurality of subcarriers of said OFDM wireless network; decrypting said second encrypted message using a fourth decryption key, said second encrypted message comprising said financial transaction information; decrypting said decrypted second message using a second decryption key, and store said financial transaction information; and sending to a display at least a portion of said financial transaction information. - View Dependent Claims (10, 11, 12, 13, 14)
