launched a sleepwear for small children that contain RFID tags (which when passed from the reading
device alarms), providing some peace of mind to parents, who might fear that their young ones may be
abducted while they are asleep [CLO05].
9.3.8 Golf Ball Tracking
RFID can also help in tracing golf balls. When a player plays a shot off the fairway into the unknown
place and if no RFID tag is embedded, this may result in time wasting in surfing the ball or possibly
the ball gets lost. Importantly, when multiple players are playing in the same area this possibly results
in ball mix-up if all or some are using the same brand [GBT04]. This situation can be prevented by
tagging the ball with an RFID tag with a unique ID. Not only does it save money but also speeds up
the game. The reader, a handheld device with an LCD screen and a pulsing audio tone, is generally
used to pinpoint the right ball when the ball is in its effective range (roughly 10–30.m). It would not be
long before a new golf will come embedded with an RFID reader to detect RFID-embedded golf balls.
9.3.9 Crowd Control
A visitor control and tracking system for a venue having various access points and multiple destination
points include a monitoring system that tracks location and movement of visitors to the venue. In
accordance with the invention, a monitoring system tracks a location and movement of individuals or
crowds in the venue and works in combination with a distributed network of screening units or kiosks
to provide effective crowd control and monitoring. In one embodiment, the monitoring system employs
RFID tags or devices, which are distributed at kiosks to visitors entering the venue. A plurality of RFID
readers or receivers is arranged about the venue and function to scan for the RFID devices. A central
control, operatively connected to each of the RFID receivers, tracks location and movement of each of
the RFID devices to determine a visitor-associated metric for each of the plurality of destination points
[VCC07]. In another embodiment, the visitor-associated metric is simply established by visual crowd
monitoring [ESM06]. For example, RFID will help control crowd trouble at the World Cup, says FIFA.
More than 3.5 million tickets will be sold with an embedded RFID chip containing identification information,
to be checked against a database as fans pass through entrance gates at all 12 stadiums, in June.
It is the first World Cup tournament to use RFID technology to identify cardholders. But, if one senior
FIFA official has his way, the amount of personal information required of fans all of which is quickly
identifiable with the help of RFID will be kept to a minimum at future events.
9.4 access Control
Access control is another area that needs key attention so as to avoid the risks of terrorism and theft.
In the past manual, procedure was used for accessing the building premises, such act of assessing the
building had increased the chances of theft and terrorism [AC07]. The efficient access control system is
generally demanded by many civil and military organizations, because of many reasons, which include
• Enhanced security to limit access to restricted areas
• Tracking employee activity
• Efficient and secure entry and exit
• Improve loss prevention
The various solutions were proposed like barcode, magnetic stripes, and proximity readers, all rely
on the user to either make contact or place the badge very close to the reader. Also, for example, the barcode
scheme has another problem of reading once at a time in addition to the line of sight issue. To address
the above listed issues and the drawbacks of the proposed access control schemes like barcode, etc.,
researchers proposed RFID access control system, which can provide an easy and efficient solution.
Using RFID for access control has the following advantages:
