How does one go about taking care of one’s property - one’s worldly belongings? Well, most people keep their money in the bank, store the jewellery in a safe and insure the rest. But insurance is not really taking care of your assets, is it? It is taking care of yourself so that you do not have renew them with your own money.
In the old days, and even now, I suppose in some countries, you would employ a boy to watch over your sheep or cattle or bring them in at night for fear of lions, wolves or thieves. These were an early kind of security guard and indeed wealthy people had and frequently still do have private body guards.
What if you had a substantial office with a hundred laptop computers - laptops because employees had to do field work as well? How would you keep track on all those? A car is another good case in point and construction site plant is being stolen all the time even from under the watchful gaze of (or with the help of) private security firms.
So what can you do? Get dogs? That works sometimes, but they can be poisoned. Get video cameras and passive infra-red movement sensors linked to a control centre? That works and many firms and private houses have it, but it is very expensive.
As a cheap alternative, the police were giving out free pens in the UK, which wrote in invisible ink. The idea was to write your postcode and house number. This ink became visible under a special kind of light. That is fine if you have a suspect or found property.
Bar codes are not practical, the pen is better. It all comes back to insurance or surveillance.
However, there is another technique that is becoming affordable. The concept has been around for about 85 years, but it was too expensive to use on anything less significant than an airplane or a battle tank.
I am talking about radio frequency identification or RFID for short. The idea is the same one that aircraft have been using since during the Second World War - a transponder emits precoded information in response to a demand from an RF reader.
Information concerning ownership and particulars of what the item is can be written to an RFID chip also known as a tag and the tag can then be taped inside the object that it is to safeguard.
There are two varieties of tag: the passive and the active. Passive tags will only reply if information is requested by a reader, whereas an active tag is always broadcasting.
Many entrepreneurs use RFID tagging to keep track of their assets. In the instance of livestock, most cattle are tagged these days. Most big offices have their IT devices tagged as well and we all know that clothing stores have been tagging garments for years, although maybe you did not know what that button was that they were taking off at the checkout.
Individuals are already tagging their dogs, cats and cars and it will not be long before these asset management techniques will be used extensively at home as well. Insurance companies may demand on it.
