Power Doors

This article was triggered by a read that one can unlock the car using a mobile phone. The mobile signal frequency might just match with the frequency of the “unlock wave” and hence. Lets see how they work.

Here are some of the ways that you can unlock car doors:

  • With a key
  • By pressing the unlock button inside the car
  • By using the combination lock on the outside of the door
  • By pulling up the knob on the inside of the door
  • With a keyless-entry remote control
  • By a signal from a control center

In some cars that have power door locks, the lock/unlock switch actually sends power to the actuators that unlock the door. But in more complicated systems that have several ways to lock and unlock the doors, the body controller decides when to do the unlocking.

The body controller is a computer in your car. It takes care of a lot of the little things that make your car friendlier — for instance, it makes sure the interior lights stay on until you start the car, and it beeps at you if you leave your headlights on or leave the keys in the ignition.

In the case of power door locks, the body controller monitors all of the possible sources of an “unlock” or “lock” signal. It monitors a door-mounted touchpad and unlocks the doors when the correct code is entered. It monitors a radio frequency and unlocks the doors when it receives the correct digital code from the radio transmitter in your key fob, and also monitors the switches inside the car. When it receives a signal from any of these sources, it provides power to the actuator that unlocks or locks the doors.

And if one can replicate this signal, this frequency, things can work!

ATM Skimming Machines

The picture below got me to think about researching on this topic

Clearly, this kind of a card data theft can be extremely dangerous. For all you know, you might have already been a prey.

Here’s a laundry list of ways the ATM machine could be skimmed.

This is an amazing presentation on ATM Skimming. Need to be careful the next time you are swiping your card in the ATM machine.

ATM Skimmers are available for sale here




So what’s this blog about?

Another attempt? Well yes. Attempting to figure out another sustainable model (there are some other attempts going on parallel-ly). Well, we have a lot of questions in mind. we read up stuff, we do some research to find answers to these questions. This is an attempt to publish that little 15-20 minute research.
