Good read, for sure.

Do you have any trouble using these cards anywhere? Do you use them for normal online bill pay, online ordering from stores (or ebay/amazon, etc)?

What happens if you, say... Put $200 on a card to pay some bills and you have a $1.28 balance left over or something on the card. Anyway to transfer that to another card or do you just lose it if you can't find a small purchase to apply that balance towards? (So in a way, an added fee to the original card purchase?)

Operations Security

What is OPSEC?

Operations Security, or OPSEC, OPSEC is about minimizing attack surfaces and single points of failure through proper habits and policies. It's a systematic and proven process that we can use to deny adversaries information they need to do us harm or interrupt our plans. It's also a mindset that can be applied to any mission or plan.

Although the term originated in the military, OPSEC is now used for so much more. This includes law enforcement, computer and network security, home safety, travel, and so much more.

OPSEC isn't a list of rules, and it's not as simple as using a VPN and keeping your mouth shut. It includes elements of INFOSEC, APPSEC, NETSEC, COMSEC[TRANSEC/SIGSEC/EMSEC], PHYSEC[PERSEC], and (CO)INTEL.

THE OPSEC PROCESS

Identify the information you need to protect
Analyze the threats
Analyze your vulnerabilities
Assess the risk
Apply countermeasures

Understand your own risk/threat model: Who is your adversary? What needs protecting?

The OPSEC Two-Step: Know what to protect and know how to protect it.
