Barcode
technology is on its way out. Or is it? With the coming of RFID
(Radio Frequency Identification), it was postulated that RFID chips would
take the place of barcodes. So far, this does not appear to be the
case. While RFID use has become more common, it has not taken over.
Zebra labels
have taken the view that RFID and barcodes can complement each other.
In fact, the “smart label” from Zebra fuses the technologies, creating a
bridge from the use of one to the use of the other.
Smart labels
contain RFID inlays as part of the label itself. This
Zebra label
has a double layer of coding, capable of being read by both barcode readers
and an RFID interrogator (reader). Of course, all this extra coding does
make them much more costly than either direct thermal or thermal transfer
barcode labels.
These
Zebra labels
are fairly new to the market but they have been very
successful, especially in situations where security is of the utmost
importance. The different types of inlays are divided into groups based on
their performance as well as the orientation in which they are read.
Omni-directional can be read in any direction and are the highest
performing. High-gain and standard must be read in a specific direction.
There are four standard, four high-gain and five omni-directional inlays
available from
Zebra labels. The standard group is available in
three label sizes: 4x1, 4x2, and 4x6. The high-gain group has all but the
4x1 size option. The omni-directional group is available in 3x3, 4x4, and
4x6 labels. With all these options, plus the encoded material, successfully
counterfeiting a smart label is of the utmost difficulty.
Will RFID
take the market away from barcodes? Perhaps someday, but currently RFID is
too costly to replace the relatively inexpensive barcode technology for
everyday items. Where security is paramount, however,
Zebra labels
have it covered with their ingenious smart label.
