How Key Tags Work
Monday, February 7th, 2011Everyone has at least one key tag these days. It may be a supplement to a credit card or an easier way to keep track of a gym membership or simply a way to take advantage of sale prices at the local grocery store. In fact, over half the American public has at least one key tag and most have multiple tags. If you take out the population that is children, that percentage jumps much higher.
A key tag operates on the same principle as the full size cards people carry in their wallets. It is a piece of plastic that has data embedded inside. This is usually in the form of a magnetic stripe , such as the visible strips on a credit card, drivers license or gift card. In key tags, the magnetic component is hidden from view and much smaller. However, it is still capable of communicating with the same readers as the card form. They can also be read by barcode scanners and other types of readers.
Key tags have risen in popularity over traditional cards because they are smaller and more versatile. Because they are kept on a key ring, they are easier to access than shuffling through cards in an overstuffed wallet. They are also much less likely to be dropped or lost than a card which makes them that much more attractive to consumers.
