Images of RFID

Let’s understand the concept of Images of RFID. Literally there are many ways to get real Images of RFID. ADSL and other broadband services are proliferating at an increasingly rapid pace, and the distribution of stored image contents has now begun. Users can obtain network cameras at an affordable price, and we can expect to see a steady increase in the types of images that can be used, including live images sent by video phone. We expect that there will be an increase in demand for simpler selection of images that are of interest to users from among the huge number of available images.

There are various methods for obtaining positioning information such as PHS (personal handy-phone system), GPS (global positioning system) and RFID (radio frequency identification) tags and to take Images of RFID. RFID tags come in active (with built-in battery) and also passive types. Table below shows a simple comparison of these four methods. RFID tags can be used outdoors, but the installation of receivers has not yet reached the point of being a true infrastructure, and applications are limited to spot usage in the immediate vicinity of the receivers.

Passive RFID tags can only be used in close proximity to the receiver, while active RFID tags have a limited battery life. PHS is basically designed for outdoor use, but antennas are now being installed indoors, mainly in public facilities, providing a road scope of applications. Even so, the positioning accuracy is around 100 meters. GPS can only be used outdoors. Each of these methods thus has limitations, so methods must either be selected according to the service content, or combined so as to complement one another. Many developed systems are unique in the sense of being a combination of image systems and RFID systems.

	Position identification accuracy, etc.	Indoor use	Notes
Active RFID tag	Can be used within approx. 10 m dia.	Good	Requires internal battery in tag. Can be used for several years, depending on transmission intervals.
Passive RFID tag	Operates at close range (1 m or less)	Good	Powered by external radio waves, so frequency and distance between tag and receiver are limited.
PHS	Position identification accuracy: about 100 m	Fair	Positioning accuracy is rough. Can be used indoors in some cases, depending on antenna installation conditions.
GPS	Position identification accuracy: about 10 m	Poor	Cannot be used indoors. Good positioning accuracy when corrected using map information.

Existing Images of RFID systems cannot identify the subject in images. Some systems can identify the subject among several dozen people. They enable users to select camera images of the subject, who is identified by an active RFID tag placed on him or her, and to view the images via the Internet on suitable terminals. In the system introduced here, we chose the active RFID tag system as the most appropriate method for use in indoor facilities and within the range of the cameras being used (approximately 10 meters in diameter). Here we explain the functions for use in a kindergarten as a typical application.

They have developed image systems combined with positioning systems. These enable them to create new services for broadband users. The number of live Images of RFID is expected to increase even more in the future, with mass media images of interest to many people and individual images targeting a small number of users (e.g., images from cameras installed in kindergartens and daycare centers). The provision of attractive images as well as convenient and easy-to-use services holds the key to the future proliferation of broadband. The RFID tag image system introduced here will contribute to the further popularization of broadband applications, though it needs to be improved.

Reinforcing the public Images of RFID: the industry's next potential hurdle: The RFID market has clearly reached an inflection point. Recent major announcements include Gillette's order of 500 million ePC tags and Benetton's rollout of an item tracking system that has an estimated annual requirement of 15 million IC units. Through numerous developments in the RFID market, the major barriers of price and standards are being addressed to help spur adoption. However, a potential new challenge looms: industry players need to manage public scrutiny of high profile RFID applications, especially as they relate to consumer markets.

As with any new/emerging technology coupled with Images of RFID, a certain degree of skepticism is to be expected. The issue now becomes how public skepticism is managed by the industry. The recent announcement by Benetton stating that they will be embedding RFID transponders in items of clothing and onto shipping cartons has been received with some uncertainty. This is largely due to potential consumer privacy concerns raised by some media sources and privacy advocate groups (such as CASPIAN). The Benetton announcement did not clearly state whether the company would deactivate transponders before customers left the store. According to sources at Philips Semiconductor, Benetton presently plans to deactivate the tags at the point of sale. However, the potential ramifications of the misconception cannot be understated.

With RFID looking to gain momentum as a viable supply chain-tracking solution, especially in the consumer goods sector, industry participants need to very clearly communicate how RFID technology is being used and how it relates to average consumers. According to Michael Liard, "RFID suppliers need to acknowledge that the mainstream press and everyday consumers are not necessarily familiar with the performance capabilities of RFID technology and the applications which RFID supports. It is conceivable that misconceptions about how RFID is being used could further delay the rollout of future RFID solutions and negatively impact the public's opinion of RFID technology."

RFID industry participants need to more closely Images of RFID their public relations and communications campaigns. This is especially true as the primary audience shifts from technology insiders to technology outsiders. If industry participants skirt the privacy issue and do not directly address the topic, it may open the door for a potential bevy of negative press that could impede the progress of the RFID market. VDC recommends that industry players properly equip themselves to enact countermeasures to address emerging privacy concerns that are being associated with RFID technology.
