In constrast to a barcode which is ink on paper and is basically one scan beam one read; a RFID tag has a scan field where many tags can be read at a time given that scan fields overlap. In a nutshell a stationary or portable RF reader sends out a signal through its scan field. Any tags in the field take power from that signal and respond by sending their data back to the reader. The reader takes attendance, ignores the duplicate responses, and negotiates any data collisions. Then the reader transmits the short list to “the system”.

RFID has some extra complications. Different tag antennae are required for different applications. The only way to be sure is to test. Don’t be surprised to see different tag specified for products containing different materials. A canned good may take one antenna while a dry good would take another. If you are lucky, you might find one model of RFID tag that works for all or your cases and pallets.

Because of this complexity, qdata has created the RFID Try n Buy Program. This is a simple and low cost method of effectively testing and proving if RFID is the correct way to proceed for your chosen application.

We will perform the following:

• review of the intended RFID application
• create measurable objectives
• review of suitable RFID technologies for your application
• site mapping of your facility or area where you need RF coverage
• work flow design of the RFID application in conjunction with the recommended technology set
• creation of a pilot that will allow you to establish a budget and define the scope of the pilot

Upon completion of the pilot you will then have the option to purchase the equipment or simply walk away.

To learn if you qualify for our Try n Buy program please contact qdata at 800-900-SCAN and ask to speak to our RFID specialist
