Abstract

A reader is proposed that includes a reader core having a web server provided thereon. The web server is made accessible to users via an advertised IP address. One set of scripts made available via the web server provide a user with the ability to optimize a tuning network for the reader.

Claims

1. A method, comprising:

determining an IP address of a web server contained within a reader core of a reader;

entering the determined IP address into a web browser of a computing device;

obtaining, from the web server, at least one antenna calculation web page, the at least one antenna calculation web page comprising instructions, directions, and/or formulas for determining a tuning capacitance value for use with the reader; and

rendering the at least one antenna formula web page on a user interface of the computing device.

2. The method of claim 1, further comprising:

receiving instructions to measure at least one parameter of an antenna to be included in a credential interface of the reader; and

providing a measurement of the at least one parameter as an input to the at least one antenna calculation web page, wherein the at least one antenna calculation web page uses the measurement to determine the tuning capacitance value; and

rendering the at least one antenna formula web page on a user interface of the computing device with values calculated by the formula represented on the antenna calculations web page.

3. The method of claim 2, wherein the tuning capacitance value correlates to an antenna having a predetermined inductance and wherein the tuning capacitance value include both a capacitance value for a series tuning capacitor and a capacitance value for a parallel tuning capacitor.

4. The method of claim 1, further comprising:

configuring the reader to emulate a mass storage device a first time that a communication link is established between the reader and computing device;

causing the reader to install a driver on the computing device which enables the computing device to access the web server via the web browser;

determining that the driver has been successfully installed on the computing device; and

in response to determining that the driver has been successfully installed, altering a behavior of the reader to no longer emulate a mass storage device.

5. A computer-readable medium comprising processor-executable instructions that, when executed by a processor of the terminal, perform the method of claim 1.

6. An RFID reader, comprising:

a processing core, the processing core having access to memory which includes antenna optimization instructions, wherein the antenna optimization instructions are made accessible via an IP address and include information which enables a consumer of the RFID reader to determine optimal parameters for an antenna that enables the RFID reader to reader RFID transponders; and

a processor configured to execute the antenna optimization instructions.

7. The reader of claim 6, wherein the consumer accesses the antenna optimization instructions via a web server running in the processing core of the reader.

8. The reader of claim 7, wherein the web server is responsive to html requests and comprises a script for generating responses to such html requests.
