Secure Digital Chips (SD Chips)

SD chips are commonly used in our technological devices. They are smaller, more versatile, and sometimes even can hold more memory than flash drives.

It was brought to my attention the other day that SD actually stands for secure digital. Which led me to question, does secure digital mean it is secure and encrypted?
As I search for the answer to this question I can upon several useful and informative links.

How SD chips came about:

Additionally, I came upon an EBay link in which informs consumers how to avoid counterfeit SD chips.

I hope this information is useful. If anyone can answer my question about how secure SD chips are, let me know.
