Overview

  • Local or Global: Selecting the right RFID technology can be a daunting task. If your application will be used in multiple countries, the choice of frequencies are reduced substantially
  • Liquids and Metals: To transmit through liquids, or around metals and corners, the choice of frequencies is again very important.
  • Tag costs: Passive tags are the lowest cost tags, but have the shortest range. Semi-active (semi-passive) tags have entered the market and cloud the choice even more.
  • Active Tags: They can transmit at will, have sensors added, and provide verification that the message is received. However, they have a finite battery life.
  • Cost of Tag vs. Interrogators: Some applications are better off using a more expensive active RFID tag that has a low cost integrator if many interrogators are used with only a few tags. Others applications may require the least cost passive RFID tag with an expensive interrogator.
  • Data security and encryption: This is an issue with some applications where it will demand semi-active or active tags.
  • Middleware solutions: Can cost anywhere from $30,000 to $100,000 and are used to interface between the RFID interrogators and some customer specified database management program.
