RFID has the capability to automate and enhance workflows and improve operational efficiencies, specifically in healthcare and life science organizations. However, there are different types of RFID technologies and their differences affect market adoption and outcomes. As RFID technology continues to evolve at a rapid rate, it is important to consider which form of RFID is appropriate for different applications.  


RFID, which stands for radio frequency identification, is a form of wireless communication that uses radio waves to identify and track objects. There are a number of forms of RFID technology on the market today. The most recognizable include low frequency (LF), high frequency (HF), and ultra high frequency (UHF).

Low Frequency (LF):

  • Frequencies from 30 KHz to 300 KHz
  • Short read range, approximately 10 cm
  • Slower read speed
  • Low sensitivity to radio wave interference
  • Applications include access control and livestock tracking

High Frequency (HF):

  • Frequencies from 3 to 30 MHz
  • Read range between 10 cm to 1 meter (3 feet)
  • Moderate sensitivity to radio wave interferences
  • Applications include ticketing, payment, and data transfer applications
  • Several HF standards in place

Ultra High Frequency (UHF)

  • Frequencies from 300 MHz to 3 GHz
  • Read range up to 12 meters (40 feet)
  • Comply with the global, universally adopted UHF Gen2 standard (EPCglobal Gen2 ISO 18000-63)
  • Use the 860 to 960 MHz band
  • Fastest growing segment of RFID technology
  • Cheapest tag to manufacture
  • Application of UHF technology spans many markets; including retail, healthcare, life science, pharmaceutical, anti-counterfeiting, transportation, and manufacturing  


Ultra high frequency technology, referred to as RAIN RFID, is the fastest growing segment on the RFID market. The majority of new RFID projects are using UHF, as opposed to HF or LF systems. To date, UHF technology has over 20 billion connected items providing real-time visibility and data to a myriad of everyday items. UHF systems are known for generating long read ranges, up to twelve meters (forty feet), whereas HF systems carry a much shorter read range of approximately one meter (three feet). UHF allows for a faster data transfer rate, up to 20 times the range and speed of HF systems. This enables quicker transaction capture times and faster data processing.

As UHF solidifies its position as the global standard and preferred RFID technology across vertical markets, tag prices continue to drop. In 2017, UHF RFID tags cost approximately $.05 to $.15 per tag, whereas HF tags range from $.50 to $2.00 per tag.

Using a UHF RFID system eliminates the need for manual processes, thus increasing inventory visibility and automating workflows. There are countless benefits to incorporating UHF RFID systems into healthcare and life science markets, including:  

  • Gain real-time visibility of inventory
  • Automate inventory tracking and workflows
  • Prevent use of expired or recalled products
  • Meet industry regulations such as FDA, UDI, and JHACO
  • Remotely monitor temperature and inventory alerts
  • Reduce shrinkage and prevent inventory stock-outs
  • Secure access to specified areas or products
  • Improve overall business operations
