RFID in a nutshell

What is Radio Frequency Identification (RFID)?

RFID or Radio Frequency Identification is a technology that provides wireless identification of people or assets.
A RFID tag is attached to an object and contains information about that object. The basic units of any RFID based systems are small RFID tags – devices which emit RF signals either at periodic intervals (active RFID technology) or when they come in close proximity to an RFID reader (passive RFID technology).

For active RFID solutions, the sensors are mounted at regular intervals throughout a facility, blanketing the entire region in a sensory network, which can pick up the location of a tag anywhere in the system. When the tagged object passes within range of an RFID reader (line of sight is not required), the reader will pick up the wireless signal from the tag and the information can then be transferred to a computer system for processing.

This makes it possible to track objects within a controlled environment, which may be a warehouse, a hospital, a high-security building, or wherever important valuable assets need to be tracked closely. Processes can be automated by including item specific information or instructions within the tag.

RFID value across  the industries

RFID is also expected to  unlock value  across  multiple industries.  While  retail  and  consumer   product companies   have  been   among   the  first  to  invest  in RFID and  the  emerging  Electronic Product  Code (EPC) standards,  LogSystems  sees  tremendous  potential   in the electronics, automotive, healthcare, retail and pharmaceutical among others.

The following engagements represent tangible examples of RFID benefits:

  • A semiconductor  manufacturer  is deploying  RFID in   manufacturing   and    distribution    operations, and is beginning to see reduced  inventory and logistics costs and improved visibility
  • An automobile distributor  is deploying  RFID as an enabler for import and inventory management, and has improved vehicle location and processing times
  • A pharmaceutical manufacturer is seeing  lower product handling and mate¬rial tracking costs by leveraging  RFID and related  sensor technology in a temperature-controlled environment

  • A food manufacturer is seeking accurate raw material usage tracking and recipe management by leveraging RFID in raw material  allocation  and  manufacturing operations
  • A book retailer implemented the “intelligent Shop” where the inventory is online collected and the customers  are targeted personally inside the  shop, based on their prior shopping and the current selections.

  • A retailer  has  identified  opportunities to  improve on-shelf  availability by  deploying  EPC technology within the store to monitor shelf replenishment.

Technology readiness

Most often associated with inventory tracking and supply chain   management,  RFID applications   are   growing rapidly.  From  manufacturing  facilities to  vehicles,  to airport   military  compounds,  store   shelves   and   toll booths, this technology – which has actually been available since 1969 – is steadily (and inevitably) transforming how the world does business

RFID enables   users   to   access   information   –  serial numbers,  colors  and  sources,  for  example  –  from  a remote  location. The technology  is based on a relatively simple concept that relies on radio waves to transfer data from a preprogrammed tag to a reader.

  • Tags:  – active, passive or semi-passive – that store information
  • Readers  – stationary and handheld – that read/write information from the tags

Companies  need  confidence  in performance and reliability to depend on new technology to manage their businesses. Over the past 24 months, RFID read reliability, tag  application,  and  reader  and  software  performance has improved  dramatically; however, there  is still room for improvement.

Our partners  Impinj and Reva are the  leaders  on Word Wide level  in  RFID technology.  As strategic  partners for these  companies  LogSystems has the  highest  level support.

We believe  RFID will follow an evolutionary  path  that is accelerated, but  similar to  many  other  technology initiatives that  have come  before  it, such as electronic data   interchange,  the   UPC  bar   code,  point-of-sale systems  and  global  data  synchronization.  Deployment has already begun  with early adopter pilots (Philips, HP, IBM, UPC, Sernam), and broader  implementations (Wal Mart,  Metro  Group,  Sony,  HP Foxconn,,BGN) and  will accelerate toward expansion where open standards, technology  stability,  enhanced  solution  options   and lower implementation costs combine  to drive a critical mass of adoption.

Tecnologies

An RFID system consists of a tag made up of a microchip with an antenna, and an interrogator or reader with an antenna. The reader sends out electromagnetic waves. The tag antenna is tuned to receive these waves.

A passive RFID tag draws power from the field created by the reader and uses it to power the microchip’s circuits. The chip then modulates the waves that the tag sends back to the reader, which converts the new waves into digital data.

What is the difference between low-, high-, and ultra-high frequencies?

Just as your radio tunes in to different frequencies to hear different channels, RFID tags and readers have to be tuned to the same frequency to communicate. RFID systems use many different frequencies, but generally the most common are low-frequency (around 125 KHz), high-frequency (13.56 MHz) and ultra-high-frequency or UHF (860-960 MHz). Microwave (2.45 GHz) is also used in some applications. Radio waves behave differently at different frequencies, so you have to choose the right frequency for the right application.

Do all countries use the same frequencies?

Most countries have assigned the 125 kHz or 134 kHz area of the radio spectrum for low-frequency systems, and 13.56 MHz is used around the world for high-frequency systems. But UHF RFID systems have only been around since the mid-1990s, and countries have not agreed on a single area of the UHF spectrum for RFID. Europe uses 868 MHz for UHF, while the U.S. uses 915 MHz. Until recently, Japan did not allow any use of the UHF spectrum for RFID, but it is looking to open up the 960 MHz area for RFID. Many other devices use the UHF spectrum, so it will take years for all governments to agree on a single UHF band for RFID. Governments also regulate the power of the readers to limit interference with other devices. Some groups, such as the Global Commerce Initiative, are trying to encourage governments to agree on frequencies and output. Tag and reader makers are also trying to develop systems that can work at more than one frequency, in order to get around the problem.

EPC Gen 2 And EPC Mark

What is EPC Gen 2?

Gen 2 is the shorthand name given to EPCglobal’s second-generation EPC protocol. It was designed to work internationally and has other enhancements such as a dense reader mode of operation, which prevents readers from interfering with one another when many are used in close proximity to one another.

Why is EPC Gen 2 important?

Gen 2 was designed to work internationally and has other enhancements that are significant, but the real benefit of Gen 2 is that it works anywhere in the world and major manufacturers of chips and tags have lined up behind it. That competition will drive up volume and drive down price. The first Gen 2 tags arrived on the market in the third quarter of 2005 and several companies, including Avery Dennison and UPM Rafsec, announced low-priced tags. Lower prices and the ability of tags to work internationally will drive adoption.

Meeting the Mark

EPCglobal Certification Testing-What it Means, Why it Matters

Key to market proliferation of UHF Gen 2-compliant products is the EPCglobal program to certify the hardware that implements the standard. This includes the testing of tag chips, readers, and printer/encoders with embedded reader modules. Products that pass the tests conducted by MET Laboratories (an independent 3rd-party lab contracted by EPCglobal) earn the EPCglobal certification marks, “seals of approval” indicating the products’ adherence to the stringent requirements of the standard. Says EPCglobal president Chris Adcock, “We want to enable companies that are implementing EPCglobal Standards in their businesses to have easy access to unbiased, objective and reliable information about EPC hardware. This way, companies will be better able to focus on their business at hand and have confidence in the products they select for EPC implementations.”

To this end, EPCglobal has defined three phases of certification: compliance, interoperability, and performance—each of which is described below.

Compliance
Compliance testing verifies that products comply with the UHF Gen 2 standard, and products bearing the certification mark are your assurance that they have been rigorously tested against EPCglobal standards. Monza is the first tag chip to achieve certification, while Speedway was one of first readers certified for operation in all modes of the Gen 2 standard, including “dense reader mode”. The dense reader mode was designed specifically for environments such as distribution centers and warehouses where a high number of readers must operate without interfering with each other. Shown below are the compliance marks for Impinj’s Monza tag chips (left) and the Speedway reader (right).

Interoperability
Interoperability testing builds on the compliance certification and verifies the ability of different compliance-certified Gen 2 components to work together. Interoperability is a cornerstone of Impinj’s product development efforts. Despite the obvious advantages of assuring interoperability among products, not all RFID vendors have been able to achieve this level of certification. In fact, Impinj is the only company to have earned Gen 2 interoperability certification for both tag chips and readers. By earning both certifications, we can assure our customers that their Impinj-powered tags and readers interoperate flawlessly with other Gen 2 certified products. Shown below are the interoperability marks for Impinj’s Monza tag chips (left) and the Speedway reader (right).

Performance (Q1’07)
Clearly, certified UHF Gen 2 interoperability is a major milestone in the development of RFID systems. As important as that is, though, performance is still what matters most to RFID deployments. RFID hardware must have a high degree of receptivity, meaning both tags and readers are not only extremely sensitive to each other’s signals, they are also able to reject the interference from other RF sources operating in the area. EPCglobal, recognizing the critical importance of receptivity to system performance, created a working group to address these and other issues. In the process of defining minimum requirements, they’ll address not only the performance of tags applied to various classes of products—such RF-friendly materials as paper, plastic, wood and so forth, as well as more problematic materials such as liquids and metals—but also the key aspects of tag performance: sensitivity, interference rejection, orientation, electrostatic discharge (ESD) and others parameters. Once the objectives are defined, the EPCglobal Hardware Action Group will draft the specifications for performance testing. And this will complete the promise outlined by the framers of the UHF Gen 2 standard.

The promise  of RFID

RFID technology  introduces   a  wide   range   of  new capabilities  with  the  potential   not  only  to  optimize current  business  processes, but  ultimately  create  new ways of doing  business  that  are anticipated to deliver unprecedented value, within and across company boundaries.

Unlike barcodes, RFID  can  read  multiple  tags  at  one time, with no line of sight required. RFID tags  are less vulnerable  to  damage,  and  offer  significantly  higher data capability to capture  detailed  product  information. RFID also offers the  potential  for read/write  capability – makings tags reusable.

Among these capabilities, RFID can help:

  • Expedite transaction  processing  by eliminating  the need  for line of sight and  manual  scanning  that  is associated with the use of bar codes or other manual data collection processes.
  • Improve value chain visibility and inventory control by creating the ability to “see” the location of actual products and other assets – in realtime
  • Enable track and  trace  authentication through  the identification  of discrete items at the various points in the lifecycle
  • Power “triggered” processes  or automation  in business  areas  like replenishment,  manufacturing and operations
  • Improve data collection accuracy for the purpose  of business intelligence and realtime decision-making

By relaying  data  about   location,  design  and  history to  a  remote   automated reader,  RFID  technology has the  potential  to  radically improve  the  effectiveness  of tasks as varied as inventory  control, production,  check in and  check out,  and  homeland security. Using RFID, organizations  can track products, parts  and services in the  warehouse and  on the  assembly  line on the  road, in the  store  and at baggage counters  in planes, trains, ships and ports, and in the field.

THE RESULT?

The ability to lower costs and heighten efficiencies tighter compliance  with health,  safety and  security mandates better  customer  care and  more  satisfying returns  from the assets that drive operations. The key is to start now -and start smart.
