  2. Opportunities through Radio Frequency Identification (RFID) system

  3. What is RFID? RFID is an Automatic Identification technology of gathering data about a particular item without the need of touching and seeing the data carrier through the use of inductive coupling or electromagnetic waves. The data carrier is commonly known as Transponder or Tag and the latter which energizes the tag to transmit information is known as Transceiver or Reader • First Bar code patents – 1930s • First use of RFID device – 2nd world war – Britain used RFID-like technology for Identify- Friendly and enemy aircraft • First RFID Patent - 1973 • UHF RFID got a boost in 1999, when the Uniform Code Council, EAN International, Procter & Gamble and Gillette put up funding to establish the Auto-ID Center at the Massachusetts Institute of Technology • Auto-ID center founded at MIT – 1999 • Standardization effort taken over by EPC Global (Electronic Product Code)

  4. A typical RFID system comprise of two types of elements • Hardware: 1. RFID Tags or Transponders • Integrated Circuit (IC) • Antenna • 2. Protective Packing (determined by application) • 3. Computer • 4. Reader • Software: 1. Middleware (eg., Oracle, SQL server, MySQL) • 2. Web Application Software • RFID Tag:An RFID tag is an object that can be applied to or incorporated into a product, animal, or person for the purpose of identification and tracking using radio waves. • Passive Tag: A passive tag is an RFID tag that does not contain a battery; the power is supplied by the reader • Active Tags: An RFID tag is an active tag when it is equipped with a battery that can be used as a partial or complete source of power for the tag's circuitry and antenna. • RFID Reader:An RFID reader typically contains a module (transmitter and receiver), a control unit and a coupling element (antenna). The reader has three main functions. • 1. Energizing • 2. Demodulating • 3. Decoding • RFID Middleware:RFID middleware applies filtering, formatting or logic to tag data captured by a reader so the data can be processed by a software application.

  5. Fig.1 RFID system operations Near field coupling for RFID tags use strong magnetic field to detect. This is a valid mode of operation at lower frequencies (13.56 MHz). At microwave frequency, the effective wavelength seen by the tag is small enough to ensure that only far-field operation is valid. From Figure1, we see that the reader antenna emits energy which is received by the tag and is used to energize the microchip. This microchip acts as a load to the tag antenna. As the load impedance varies over time, the reflected signal from the tag will undergo amplitude changes similar to a pulse modulation. This variation is used by the reader as information received

  13. SATCOM’s Role in Design & Innovation

  14. Miniature and Wearable Ring type Passive UHF RFID Tag(Patent pending, Application no: 14/KOL/2010 ) The invention relates to the use of radio frequency (in Ultra-High Frequency band) and, more specifically to passive tags for use in radio frequency identification systems (RFID). In particular, this invention relates to a novel architecture of a passive RFID tag which is embedded in a ring worn by persons on their fingers thus miniature in size and capable of responding to UHF RFID reader interrogation from a distance of 1 foot. This invention relates to a method of encapsulating the passive tag with radio transparent materials acting as rugged ring holders and ring cap so that the encapsulated tag can withstand external environmental effects while maintaining the required performance. The commercially available UHF passive tags are usually bigger in size than the active tags. It is thus apparent form the above said that there is a need in the art for advancing the art of UHF passive RFID tag designs involving size limitations such a miniaturized tags which would be adapted further to meet the requirements for impedance match as well as achieving radiation efficiency to facilitate in the efficient tracking of the human personnel in restricted zones.

  15. Significance of the Invention Personnel identification using RFID can potentially dramatically alter the manual tracking method for people inside a restricted zone. An unobtrusive and non invasive device acting as a tracker can improve security features inside restricted zone, track patients as well as caregivers in hospitals and also act as a personnel authentication for entry and exit in regions of special attention and protection such as places of public gatherings including temples and places of religious worship and the like. This new device is a RFID tracker in the disguise of a ring; thus it offers relatively little discomfiture to the concerned people who are generally open to wear a ring.

  16. RFID Site Survey In an indoor environment, the RF propagation is uncertain (typical propagation models are empirically generated) to a large extent. This is due to multi-path scattering. Such uncertainty coupled with obvious “null” patterns seen in commercial tags leads to a lot of heartburn in the customer’s mind. It has been observed many a times that large scale RFID deployment in an enterprise, in spite of its greater value, has been scrapped because of the failure of the system integrators to grasp the finer nuances of physical medium. To overcome this problem, RFID Site Survey is required. An RFID site survey identifies optimal locations for the RFID tags on the products, as well as the optimal locations for readers so the RFID processes work satisfactorily at customer’s premises. The objective of an RFID site survey is to gather enough information and data to determine the number and placement of your work points that will provide the total coverage required. Coverage required generally means the support of a minimum data rate in a given area. SATCOM has all the expertise, experience and T & M instruments required to perform a RF survey (from LF to 6 GHz frequency) and provide a complete report to the customers along with innovative suggestions.

  18. Some RFID applications

  19. Supply Chain Management Through RFID, it is possible to enter and access real time accurate data right from Plant to Warehouse to Retail inventory. Entire process can be synchronized without any human interaction. The whole system optimizes stock put-away based on real-time information about the status of bin utilization. Improves ROI.

  20. Vehicle Tracking System RFID improves Parking lot security through automatic identification and notification of vehicle during entry and exit. It helps to create parking areas, dedicated to any organization’s staff and inaccessible to visitors and delivery vehicles. The entire tracking system is not at all affected by weather changes. The system can also manage the data necessary to help ensure that accurate parking and usage fees are charged and collected. During movement of the vehicle, data can also be captured and database.

  21. RFID enabled Document Verification RFID Tags can be embedded inside a paper document. Hitachi’s µ-chip (mu-chip) is designed to be small enough that it could be embedded in paper at the point of manufacture. The tiny chip measures just 0.4 millimeter (0.02 inch) by 0.4 millimeter (0.02 inch) and has an antenna built into it. The chip operates at 2.45 GHz and can be read only from a very short distance. Because it is so small, it feels like a little bump in the paper that is almost undetectable. The mu chip involves the electrodes, where the ends of the coiled antenna are attached. These are usually on the top of the chip, but on the new mu-chip, one is on the top and one is on the bottom. This will dramatically improve its ability to mass-produce RFID tags with mu-chips.

  22. Significance of the Invention Authentication of important documents like University certificates, Agreement Papers etc. will be easier using this embedded RFID tag. The mu-chip is an attractive alternative to applications where Barcode isn't suitable and more conventional RFID tags are too expensive. Because of its small size, it feels like a little bump in the paper that is almost undetectable. The RFID enabled document is tamper-proof and highly secured from fraudulent activities.

  23. On-line Smart Inventory Management System Simply put, real-time based Smart inventory is an inventory control system that operates in real-time. So an organization really knows what they have available every day or every hour.

  24. Objective • SIMS provides a cost effective solution for the management of inventory which leverages RFID technology. • Combines an antenna array to a single RFID reader to map out an area for inventory detection

  25. What’s the Benefit? • Automatically Manage inventory more effectively by implementing RFID Devices. • Real time visibility of product and quantity • Improve traceability of misplaced items • Theft prevention and administrative shrinkage (asset tracking) • Waste management • Planning/ trend analysis • Live updates to the database through wireless communication • Periodical Report Generations • Sync the Devices - "Automatic Handheld Synchronization" occurs each time a handheld is connected to a PC. Inventories that are conducted in the field automatically update the database

  26. RFID in Asset Management

  27. Identification of Asset Location RFID can be used to locate costly assets in a closed environment Maximum Usage of Asset in its lifetime Maximum ROI on Asset Investment Prevention of theft of valuable asset Minimum loss to the company Identification of misplaced asset Nearly zero search time due to asset misplacement

  28. Monitoring of Asset Movement RFID can be used to monitor the movement of costly assets Allow only authorized personnel to move asset Prevention of asset theft by unauthorized person Automatic recording of asset movement history Easy to identifying the cause in case of asset misplace Best possible movement of costly asset Minimum downtime due to asset movement

  29. RFID Solution Structure Assets’ information can be read simultaneously from a distance via wireless technology Assets’ data is transferred to the central system via wireless technology RFID Tag is attached to each of costly instruments ---------- ---------- ----------

  30. RFID Solution Structure Assets’ information is logged whenever they have been moved in or out particular location Assets’ movement data is transferred to the central system via wireless technology RFID Tag is attached to each of costly instruments ---------- ---------- ----------

  31. RFID Software Screenshot User can access the consolidated report of asset location, characteristics, movement history in one place

  32. RFID Software Screenshot User can view the detail information of each asset also

  33. Conclusion • One type of tag is not suitable for every possible application. • Selection of appropriate solution is very critical to the success of a deployment • The price of a tag is dependent on the context of usage • The proximity of a tag to different materials affect its performance. • Optimizing performance in a warehouse deployment requires strong background in RF technology
