7 Cool inventions that have made the world more secure

Today’s technological landscape is debatable. Some people believe that enhancement in technology is the reason the world is secure but then there are some who think otherwise.

If we weigh the blessings and destructions of inventions to date, we’d know that the world is more blessed than destroyed. In fact, technology doesn’t destroy anything, it is our actions that do.

The world has come a long way in terms of advancements and security. We have machines that do the difficult work to reduce risk. Cars come with safety features and even anti-viruses are there to stop theft.

All these inventions are enough evidence to conclude that new inventions have made the world more secure and have brought relief to people’s lives.

Let’s have a look at seven products that have really made a difference:

  • Robots

If you think that robots are constrained to movies only then think again. Robots are no more just a part of science fiction but are now in the real world, too.

In 2003, Osaka University’s Robotics Lab invented the first talking, walking and communicating robot, and today they can be seen serving people around the world. In fact, there’s a restaurant in Japan called Nagasaki which has a full robotic staff to serve customers.

Robots have even gone to space and you can now buy your own now off the marker, but they are obviously a little expensive for most people.

  1. Digital Business

Back in the days, businesses had to advertise on paper, pay in paper and write on paper. Today, thanks to digital technology, we are living a paperless life.

We write emails instead of letters. We pay in digital currency instead of using paper money and we advertise on the web instead of in the newspaper. The whole phenomenon of digitizing everything has helped minimize deforestation and save trees.

Trees are important for our environment as they help in making the surroundings healthy. Hence, it can be concluded that digitization is actually saving the environment.

  1. LEDs

The invention of blue LEDs by three Japanese scientists, namely Nakamura, Nagasaki, and Amano made it possible to lead to the invention of LED technology that we are using today.

LED devices use less energy than incandescent bulbs, allowing us to save not just energy but money as well.

  1. CCTV Technology

Walter Bruch of Germany was the first engineer to design a CCTV system. He installed it to monitor the launch of V2 rockets. However, his invention soon expanded and is now used all around the world to keep an eye on things.

  1. Magnetic Card Reader

A magnetic card reader is a device that helps to read a magnetic card. It is used for a number of purposes such as accessing cash, opening doors and using devices that work on magnetic technology.

The device reads the code on the card, making transactions more secure. Click here to know more about this amazing invention.

  1. Communication

You might not remember, but there was a time when communication wasn’t instant. One had to wait for days to get a response to a letter, and this delay caused trouble for everyone involved.

However, now thanks to phone calls, messaging and emailing, we can chat instantly. This makes the world a lot safer as one can be alerted to dangers and news can be exchanged without any trouble.

Communications has come such a long way that astronauts are now able to communicate between planets and send/receive data.

  1. Medical Industry

The medical industry is saving millions of lives every day thanks to the advent of medical technology.

Today, we have laser technology to correct eyesight, synthetic body parts that are able to mimic movement like normal body parts, tech to measure heart rate, medicines to treat tumors etc.

Are We On The Right Path?

It is natural for humans to be curious. When we see technology around us, we often wonder if it’s good or bad. Many say that this question arrives due to what we see in the movies, but the truth is that technology can be bad. You should find a balance and not depend too much on technology.
