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 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 people 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 watchful gaze of (or with the compliance of) private security companies.
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 many businesses and private houses have it, but it is very costly.
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 technique that is becoming affordable. The concept has been around for approximately 85 years, but it was too pricey to use on anything smaller 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 sends out precoded information in answer to a demand from an RF reader.
Details regarding ownership and details 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 item that it is to safeguard.
There are two varieties of tag: the passive and the active. Passive tags will only respond if information is requested by a reader, whereas an active tag is always broadcasting.
Many business people use RFID tagging to keep track of their assets. In the case of livestock, most cattle are tagged nowadays. Most large offices have their IT goods tagged as well and we all know that clothing stores have been tagging clothes for years, although perhaps you did not realize what that button was that they were taking off at the till.
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.
