RFID and Security


Destroyed credit.

Unfortunately, the number of ways this can happen keeps increasing as new technology is introduced into our lives.

The RFID chips in the credit, debit, and ATM cards that we carry in our wallets put us at risk of having our information stolen.

These Radio Frequency Identification chips are designed to make our lives easier  - no contact and transactions are processed much quicker.

The chips need a reader to capture the needed information to complete the transactions.

When we use our cards with trusted merchants, we can be assured our info is encrypted and safe with their readers.

But these readers are fairly inexpensive and when placed in the wrong hands, that's where the trouble begins.

Nefarious individuals have been known to place these readers over the trusted merchant's machines to capture our info.

We can be make ourselves aware of these instances if we pay attention, but it's the unknown lifting of our information that we need to prevent.

The pickpocket no longer needs to physically remove the wallet from the pocket these days.

He just needs to pass a reader by a wallet to capture all the credit card info he needs from the RFID chip on the cards.

Social distancing these days will help with people getting too close to do this, and there are a few other ways to block the readers from accessing the card info.

The cards can be wrapped in foil as the metal will shield them from the signals of the reader.

An RFID blocking wallet is also an option.

Wrapping your hand around the card also blocks the reader signal.

Not having the chip on your card is the most secure way to protect it.

It's hard to keep aware of everything when we're out and about in his fast paced world, so each little thing we do to protect ourselves in advance will certainly save some big headaches in the future.

Thermal Camera


Thermal imaging has been around for quite some time, but until recently, it has been unaffordable for most people.

We were lucky enough to run across a deal and were able to purchase one of these amazing units.

It is a FLIR TK Scout, and is a monocular style of thermal scope.

It has a camera and video mode to capture small resolution photos and short video clips.

There are a range of various color modes in which to view the heat profiles of objects.

As a photographer, it is the light that we chase, so it took some time to get used to looking for the heat.

Even though it looks dark in the image above, there was plenty of light when it was taken.

A dog's nose is always cold - hence the very black nose - no heat is being emitted from it.

Her eyes and face certainly loose heat as well as her chest.

The hair on her back holds in her heat more than I thought it would as Yorkiepoos tend to be colder since they don't have fur.


The chickens are really a lot more insulated than I thought they were as well.

Just their faces and feet loose heat.

The feathers do a spectacular job of keeping them warm - which is especially needed when the temps fall into the single digits.

We have skylights in our kitchen and it was surprising to see them from the outside through this scope.

We purchased this unit to bring along with us on hikes and travels so we could "see" what our eyes might be missing.

Technology gives us some added security in the woods and wherever else we may be.

Lenovo T15


After reading many reviews and putting lots of time into researching, a decision was finally made.

The Lenovo T15 Thinkpad Laptop was going to be the new addition to the office.

With so many options available, having an idea of what one is looking for in a new computer is a must.

I have been using a Lenovo G500s laptop for the last seven years, so I knew what a reliable, well put together machine that Lenovo makes

I also have been using a Dell desktop for the past nine years, and that has also been a workhorse of a machine.

The operating system hasn't changed much over this time, but the innards certainly have.

The processors are much faster which make this machine fly.

The hard drive is big enough, and the 32 GB of RAM should take us well into the future as technology grows and is always needing more.

It's very lightweight with a slim build, and the 15 inch screen is perfectly sized for viewing and portability.

But when you think about using a computer, the most important thing for the user is the amount of time spent looking at the screen.

And that's where this one shines.

It has 4K resolution.

The crispness and color of the display are just amazing.

No pixelization, no blurriness, no dullness, just sharp, vibrant, precise viewing of reports, photos, videos, and everything the internet has to offer.

It took five weeks for this machine to be built before it was shipped, but it has been certainly worth the wait.

It has a 4.8 out of 5 rating by hundreds of users, and it is easy to see why.

This little beauty will serve our home office quite well and the joy of using it is an added benefit.
