How does one go about taking care of one’s property – one’s worldly possessions? Well, the majority of people put their money in the bank, put the jewellery in a safe and insure the rest. But insurance is not really taking care of your possessions, 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 presume in some places, you would employ a boy to watch over your sheep or cattle or bring them in at night for fear of big cats, wolves or rustlers. These were an early kind of security guard and indeed rich people had and frequently still do have personal body guards.
What if you had a large office with a hundred laptop computers – laptops because employees had to do field work too? How would you keep track on all those? A car is another good case in point and construction site machinery is being stolen all the time even from under the noses of (or with the help of) private security firms.
So what can you do? Get dogs? That works usually, but they can be poisoned. Install video cameras and passive infra-red movement sensors connected to a control centre? That works and a lot of firms and private houses have it, but it is very expensive.
As a cheap alternative, the police were handing out free pens in the UK, which wrote in invisible ink. The idea was to put your postcode and house number. This ink became visible under a certain kind of light. That is all very well if you have a suspect or found property.
Bar codes are not practical, the pen is better. It all comes back to insurance or security.
However, there is another way that is becoming affordable. The idea has been around for about 85 years, but it was too pricey 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.
Details regarding ownership and particulars of what the item is can be written to an RFID chip also called a tag and the tag can then be glued inside the item that it is to protect.
There are two types of tag: the passive and the active. Passive tags will only respond if details are requested by a reader, whereas an active tag is always on.
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.
People 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 too. Insurance companies may demand on it.
