Problems solved by technology

Finally, the lifetime of the SIM card and the banking application will likely be different, and this makes provisioning and updating of the application difficult, which further strains the business relationship between the bank (in this instance) and the various mobile phone operators added complexity
Thus, to date, there is no satisfactory solution for easily adding contactless communication to portable devices that do not already have this built-in hardware and functionality

Embodiment Construction

[0029] Currently available memory cards

[0030] In 1994, SanDisk Corporation (the assignee of this application) proposed a compact flash (CompactFlash) that is functionally compatible with PC cards but much smaller TM Card (CF TM Card). CF TM The card has a rectangular shape that measures 42.8mm by 36.4mm and is 3.3mm thick and has female pin connections along one edge. CF TM Cards are widely used with cameras to store still video data. Passive adapter cards are available, into which a CF card fits and which can then be inserted into a PC card slot of a host computer or other device. A controller within the CF card operates with the card's flash memory to provide the ATA interface at its connector. That is, the host computer to which the CF card is connected interfaces with the card as if the card were a disk drive. The Compact Flash Association has established a specification for the Compact Flash card, namely "CF+ and Compact Flash Specification Revision 2.0 (CF+ and...

Abstract

A mass storage memory card adds functionality to host devices with which it is used. In addition to the ability to store large amounts of user files and protect them from unauthorized duplication, a mass storage device according to the present invention enables near field communications with a portable electronic device that otherwise does not have such functionality. In a preferred embodiment the mass storage device has a mother / daughter configuration wherein the daughter card is a fully functioning micro-SD card that can be used independently. The mother card can be accepted in an SD card slot and communicates via the SD protocol. Whether or not the daughter card is present in the mother card, a host with the mass storage device therein will be capable of near field communications. These communications can be peer to peer or can be used to purchase goods or services as a sort of electronic wallet. A controller of the device is also operable to coordinate, control, and safeguard the financial transactions made when using the device and host as an electronic wallet.

Description

technical field [0001] This application relates to flash memory based portable mass storage devices, security and radio frequency communication of data and applications within such devices. Background technique [0002] All documents (including but not limited to standards, papers and patents) mentioned in any part of this patent application are hereby incorporated by reference in their entirety and are intended to form an integral part of the teaching of this document. [0003] Electronic payments and electronic commerce in general provide great convenience to users and equally to merchants. In addition to conducting electronic commerce on the Internet, payment can now be made with cards or portable devices equipped with radio frequency. One way of doing this is by utilizing near field communication ("NFC"). NFC allows payments to be made by simply touching an NFC capable device to an NFC reader or by placing the device within about 10 to 15 centimeters of the NFC reader....
