What
Matters Most?
Recently, AIM
completed a survey to determine the most important requirement for potential
users of RFID technology. Leading the list of requirements (read barriers) was,
not surprisingly, the cost of tags. Nearly 36 percent of the respondents cited
the cost of tags, whereas 22 percent noted the overall system cost, as a
barrier. From a technical point, read-distance of the equipment was cited by
more than 22 percent as the thing of greatest concern.
Another survey,
this from The Logistics Institute at Georgia Tech University, concluded that
companies seem slow, or reluctant to use newer technologies in transportation
functions. This reluctance seems to be based on cost and complexity of
implementation. In the contradictory way of most surveys, at the same time
respondents indicated that implementing new technologies offered substantial
savings through improved planning.
RFID keeps tire info rolling
The process of
putting an identifying marker on a part is called direct part marking (DPM),
and we’ll be hearing more about it this year. The Automotive Industry
Action Group (AIAG) released its revised tire and wheel label RFID standard in
late February. Equipment manufacturers, like Intermec, are quickly stepping up
to endorse this standard. Developed by a group of users and manufacturers
within the association, the standard helps to error-proof the tire assembly
process and automate the collecting of tire information.
Suppliers of wheels
and tires to the automotive industry will now have guidelines for printing and
placement of two-dimensional bar code labels and passive read/write RFID tags.
Placed on the inside of vehicle tires, the RFID tags will identify tires that
are associated with a specific vehicle. For more information, visit aiag.org.
Everything based on the badge
At Rite-Aid’s
Mid-Atlantic Distribution Center, the 1,400 employees in the
one-million-square-foot facility need a badge produced on Zebra’s Eltron
card printers for just about everything they do.
Badges serve four
purposes at the center. They are used for photo identification, access control,
time clock activity and productivity measurement. The badge itself is an
RFID-based proximity card, custom designed, based on who ultimately wears the
badge. The Eltron printers place a color employee picture on the front and a
bar code on the back.
Everything is based
on the badge. Besides allowing employees to enter the facility and clock in, it
can measure productivity as employees swipe in at the beginning and end of
activities such as order selection in the pick-to-light operation. Data
collected indicates what an employee did in the last eight hours or, for that
matter, the entire time they’ve been employed. For more information,
visit eltron.com or zebra.com.
Tracking pallets
CHEP, a global
pallet and container pooling supplier, working with Marconi InfoChain, has
launched a program of real-time tracking of its pallets and containers. CHEP
will use customized RFID tags and a variety of fixed mobile readers from
Marconi that are compatible with established minimum performance protocol
requirements of the GTAG (global tag) Project.
By initially
focusing on the tracking of pallets through repair and inspection facilities,
damage to pallets can be identified by specific location. A more accurate
measurement of cycle times and greater optimization of asset utilization and
pallet loss can be made.
The program also
incorporates the expertise and technical strengths of Intermec
Technologies’ Intellitag technology. Savi Technology has provided its
asset management software, SmartChain, a real-time data collection software
platform that integrates with automatic identification equipment. For more
information, visit marconi-infochain.com, savi.com, intermec.com, and chep.com.
Printers do double duty
For a year or so
there has been a lot of talk about bar code label printers
“writing” information to an RFID tag placed underneath the bar code
label — creating the so-called smart label. For example, Zebra’s
R-140 printer can read, write and print labels carrying embedded ultra-thin
RFID transponders. Transponders contain integrated circuits that can be read,
programmed and re-programmed using non-contact radio waves. This revolutionary
technology enables you to change and update data repeatedly throughout the life
of the RFID smart label.
Working in a rugged
environment? Because RFID technology uses radio waves, smart labels can be read
through dirt, paint and many non-metallic objects. RFID smart labels feature
anti-collision technology, which allows you to scan and identify several
objects simultaneously, such as totes of supplies.
The question
remains, who needs this technology? “The applications for ‘smart
labels’ are starting to happen,” says Terry Pruett, director,
thermal products, Printronix, “but people won’t be putting smart
labels on every piece. The mass volume of labels will still be bar code
labels.”
The applications for smart labels will most likely be for
major subassemblies within certain industries. Pruett says the use of smart
labels will expand when someone creates applications that are high-volume and
based on RFID technology. And these applications will no doubt be in
mission-critical process applications such as aerospace or pharmaceuticals. For
