Chapter 3 — Developing and Using RFID Applications

54 IF61 Fixed Reader User’s Manual

RFID Applications and the IF61

The IF61 supports Java and C# applications. Your application

communicates with the IF61 through one of two RFID services:

• the Basic Reader Interface (BRI) server, which controls the reader

by issuing BRI commands. For more information on the BRI

server, see “Configuring the BRI Server” on page 70.

For more information on using BRI, see the Basic Reader Interface

Programmer’s Reference Manual.

• the Low-Level Reader Protocol (LLRP), based on the EPCglobal

standard. For more information on LLRP settings, see

“Configuring LLRP Settings” on page 72.

For more information on LLRP, see the LLRP Programmer’s

Reference Guide.

There are two ways to use the IF61 with your RFID application:

• You can run the application on a remote server. In this case, all

processing is performed by the server.

• You can run the application locally on the IF61. In this case, the

application resides on the IF61, and much of the processing occurs

on the IF61 and not remotely on the server.

Running your application on the IF61 improves system scalability by

minimizing network traffic, since the IF61 can handle many

processing tasks such as data filtering.

You can set up your application to auto-start when the IF61 boots.

For more information, see “Auto-Starting Applications at Boot

Time” on page 57.

If your application uses the IF61 GPIO interfaces to control external

devices such as indicator lamps, running the application on the IF61

decreases response time for those devices. For more information, see

Chapter 5, “Using the IF61 GPIO Interfaces.”

Using the RFID Resource Kit

The Intermec Developer Library RFID Resource Kit includes Java and

C# tools you can use to develop applications that enable control of

the reader and data management.
