It's not personal. They did not hack your card, they successfully hacked Home Depot. We are literally seeing a 'breach a week' being announced. Big names so far: Home Depot, Target, Goodwill, Albertsons, PF Changs, Dairy Queen, & Jimmy Johns. The credit card industry is going as quick as they can to convert the US over to 'chip & PIN' cards, and replace the magnetic stripe cards we are used to.
For me personally I use cash whenever possible. That keeps me from over spending on a debit/credit card and frankly I have more discretionary funds now then I ever did in the card days! Plus I have found that many smaller businesses will give me a cash discount if I ask. When I bought my Kubota a few years ago they gave me 10% off for cash, and that came to $2000! Say all you want about credit card 'reward programs', $2k buys a lot of stuff!
With on-line purchases I am forced to use a card. No problem. My bank will give me as many checking accounts as I want. So I opened one up and had them set it to specifically not automatically transfer funds from other accounts. I keep a base $50 in it to cover Netflix and other small recurring charges. Since I am making a purchase on-line, it is easy to log in to my bank and transfer the funds from a different account.
As I work from home, I do a lot of Internet shopping. This card number has been compromised twice in the past year. Since it does not tie to any other accounts, there is minimal risk and my bank has always covered the fraudulent charges. One was for a small amount of $10.47. I only spotted it because I saw the balance move off the $50 base. It turns out that fraudulent transaction was very common and was small enough that most people would not notice.
I don't keep lots of cash at home, but I do have some. Living out in the country, I have shown up at my neighbors when strangers turned up & went in their horse barn. I know my neighbors would do the same for me. We have a sign that reads:
Security by Glock
Insurance by Smith & Wesson
Funeral services by Kubota
I feel very secure living here.
