Radio frequency identification or RFID is the technology that uses radio signals to trak an items location; if you read about a convict being released but compelled to wear an ankle bracelet to track them, the you are looking at a practical example of RFID.
RFID has far more constructive uses than just making sure a crook sticks to a curfew. RFID tags are used to track containers and shipments even down to the individual parcel in certain cases, but the technology has recently been enjoying new application.
Wells Fargo has the job of tracking thousands of laptops from hundreds of locations and knowing when one can leave a location and who ought to have possession of it has been a security nightmare. Using RFID, each laptop has been implanted with a tag which has upon it the information necessary to automatically detect whether it can in fact leave their offices and in who’s possession it ought to be. More than this, in the event of a lost or stolen laptop, RFID can be employed to track the location of the device in order to recover it.
Though the concept behind RFID is simple, the technology required is in fact extremely complex. In this instance, complex technology does mean high cost for individual readers and tags and the price tag for most RFID solutions is beyond the budget of individual customers when insurance and ensuring back-up procedures are so much more cost effective. An RFID kit from Tiktag will probably cost in the region of $190 yet insuring the laptop against loss of theft will cost a fraction of that amount.
RFID technology is not limited to tracking assets and determining the location of missing items for big companies with car tracking technology having been around for over a decade and the benefit certainly outweighs the cost in such instances. When it comes to smaller, portable devices such as laptops, smart phones and personal items the cost effective technology for RFID tagging for personal use is still some distance away.
