Clipped Tag Development
The concept of the clipped tag was first introduced in a paper authored by IBM researchers Paul Moskowitz and Guenter Karjoth in 2005, RFID Journal, November 7, 2005. In their paper, presented at the 2005 ACM Workshop on Privacy in the Electronic Society, the authors suggest that by providing the consumer with a means to shorten the antenna, the read range of the tag may be reduced from many meters to just a few centimeters. Several mechanisms were suggested. The mechanisms included perforating the tag like a sheet of postage stamps to allow the tearing off of a portion of the antenna. Another proposed mechanism was to manufacture the tag antenna with exposed conducting lines which could be scratched off by the consumer.
IBM teamed up with Marnlen RFiD, a manufacturer of RFID labels, and Printronix, a maker of RFID printers, to demonstrate prototypes of the Clipped Tag, Wired News, May 1, 2006. The tag took the form of a garment hang tag with v-shaped notches in the edges and perforations to direct the tearing of the tag. Reactions by RFID privacy experts were favorable to the invention. According to Wired, Robert Atkinson, president of the Information Technology and Innovation Foundation, said "The Clipped Tag shows that IBM is addressing privacy concerns, even those that are unreasonable." Subsequently, IBM and Marnlen RFiD announced that Marnlen had licensed the technology from IBM and was shipping samples to select users, RFID Update, November, 2006.

Famous quotes containing the words clipped, tag and/or development:
“To treat a “big” subject in the intensely summarized fashion demanded by an evening’s traffic of the stage when the evening, freely clipped at each end, is reduced to two hours and a half, is a feat of which the difficulty looms large.”
—Henry James (1843–1916)
“I believe in the flesh and the appetites,
Seeing, hearing, feeling, are miracles, and each part and tag of me
is a miracle.
Divine am I inside and out, and I make holy whatever I touch or am touch’d from,
The scent of these arm-pits aroma finer than prayer,
This head more than churches, bibles, and all the creeds.”
—Walt Whitman (1819–1892)
“Dissonance between family and school, therefore, is not only inevitable in a changing society; it also helps to make children more malleable and responsive to a changing world. By the same token, one could say that absolute homogeneity between family and school would reflect a static, authoritarian society and discourage creative, adaptive development in children.”
—Sara Lawrence Lightfoot (20th century)
