The present application relates generally to communication between a device and a smart card reader for reading a smart card and, more specifically, to optimizing the performance of a smart card driver.

A device that reads information from, or writes information to, a smart card typically does so using a smart card reader. The smart card reader may be connected, e.g., through a directly wired connection or a wireless connection, to the device. Specific software, called a “driver”, is generally executed by the device to facilitate reading from, and writing to, the memory component of the smart card using the smart card reader. The driver includes an application programming interface (API) that allows other programs to issue requests and commands that will be understood by the driver. An API generally comprises a source code interface that a computer system or program library provides in order to support requests for services to be made of it by a computer program.

When the connection between the device and the smart card reader is wireless, for example, using the Bluetooth™ wireless communication protocol, some complications arise. In a typical transaction, the device transmits, over the wireless connection, a request to the smart card reader and the smart card reader forwards the request to the smart card. The smart card then responds to the request with a response and the smart card reader forwards the response, over the wireless connection, to the device. Unfortunately, the speed (e.g., measured in bits per second) generally available for the wireless connection limits the speed with which the device can make use of the smart card, e.g., to authenticate a user of the device. The smart card driver is located on the device and has knowledge of how to talk to the smart card which is located in the smart card reader. There are many cases where, in order to perform an operation, there is a requirement for several transactions.

By splitting a smart card driver into multiple components; with one component residing on the mobile communication device and the other component residing on the smart card reader, the smart card reader driver component is enabled to do more than merely relay communication between the mobile communication device and the smart card. By transferring part of the communication handling of the smart card driver to the smart card reader, a reduction in communication over the connection between the smart card reader and mobile communication device advantageously results in a more efficient transaction.

In accordance with an aspect of the present application there is provided a method of communicating with a smart card. The method includes receiving a command code message from a device, determining an interpretation of the command code message and, according to the interpretation of the command code message, transmitting a plurality of request command Application Protocol Data Units to a smart card. The method further includes receiving a plurality of response Application Protocol Data Units from the smart card, each individual response Application Protocol Data Unit of the plurality of response Application Protocol Data Units corresponding to an individual request command Application Protocol Data Unit among the plurality of request command Application Protocol Data Units, amalgamating the plurality of response Application Protocol Data Units into an amalgamated response and transmitting the amalgamated response to the device. In other aspects of the present application, a smart card reader is provided for carrying out this method and a computer readable medium is provided for adapting a processor in a smart card reader to carry out this method.

Other aspects and features of the present application will become apparent to those of ordinary skill in the art upon review of the following description of specific embodiments of the application in conjunction with the accompanying figures.

FIG. 1 illustrates an exemplary communication system 100 that includes a mobile communication device 106 that is enabled to communicate wirelessly with a peripheral device in the form of a smart card reader 104. A smart card 102 is illustrated mounted in the smart card reader 104.

FIG. 2 illustrates the mobile communication device 106 including a housing, an input device (e.g., a keyboard 424 having a plurality of keys) and an output device (e.g., a display 226), which may be a full graphic, or full color, Liquid Crystal Display (LCD). In some embodiments, the display 226 may comprise a touchscreen display. In such embodiments, the keyboard 424 may comprise a virtual keyboard. Other types of output devices may alternatively be utilized. A processing device (a microprocessor 228) is shown schematically in FIG. 2 as coupled between the keyboard 224 and the display 226. The microprocessor 228 controls the operation of the display 226, as well as the overall operation of the mobile communication device 106, in part, responsive to actuation of the keys on the keyboard 224 by a user.

The housing may be elongated vertically, or may take on other sizes and shapes (including clamshell housing structures). Where the keyboard 224 includes keys that are associated with at least one alphabetic character and at least one numeric character, the keyboard 224 may include a mode selection key, or other hardware or software, for switching between alphabetic entry and numeric entry.

In addition to the microprocessor 228, other parts of the mobile communication device 106 are shown schematically in FIG. 2. These may include a communications subsystem 202, a short-range communications subsystem 204, the keyboard 224 and the display 226. The mobile communication device 106 may further include other input/output devices such as a set of auxiliary I/O devices 206, a serial port 20
