It happens maybe 1 out of 10 or 20 times I use a CC, or a debit card as a CC. Put in 99999, it is marketing data collection, not security, and California merchants may not ask customers who pay with credit cards for their ZIP codes, the California Supreme Court decided unanimously Thursday.

Yes, it might be an annoyance when the police come to your door, but it is not like you will be the one doing time in prison.
Spoofing a MAC is useful only in gaining access to a wireless system that is using MAC filtering. Granted it is a easy task.
You also have to understand that the MAC never passes through the router, so there is no way to capture the MAC of a computer accessing anything on the internet.

That "annoyance" can include a week-end in jail, rooming with a guy that just beat a convenience store clerk over $50, having your name and face splattered all over the local news as a pedophile under arrest, loss of job, etc. etc..... but yes if you didn't do it, and with no job, ruined reputation and a bunch of lawyer fees to somehow pay off, you will be declared innocent as far as the police are concerned.

Ask the guys in this article how well the system works. NY case underscores Wi-Fi privacy dangers - Yahoo! News (http://news.yahoo.com/s/ap/20110424/ap_on_hi_te/us_wi_fi_warning - broken link)

Gas stations I use vary widely. Locally I use the same station almost all the time, but when we travel it's what ever is handy. I use a CC always. I have been asked for a zip code, but it was in Las Vegas, Jacksonville, etc.

It was/is an American Express, so maybe that is something from their end? I have been to all of the locations listed. I used to live in Lawrence, KS. and Minneapolis, and been to all cities you mentioned numerous times. I just never been able to simply swipe a card and begin pumping gas at the pump.
Might be the CC brand. American Express seems to be different in their requirements than other cards. Stricter, perhaps.

These are completely unrelated transaction types.

In the case of the unattended sale (gas pump) it is a security check. The zip is transmitted to the CC company as part of AVS (address verification), and should never be stored by the company (it's prohibited for PABP validation of the CC processing app).

In the case where you hand your card to a cashier, and they can swipe the card and check your signature, asking for your zip is most likely marketing.

I'm not saying that they could catch you, just that most specifically prohibit it.

And they have a right to refuse future service to me, as a consequence of my violation of the terms of service. Not a moral, ethical or criminal matter. Just a breach of contract.

If my sister is visiting, and says "I brought my laptop. I'm gonna check my e-mail", is it a breach of contract if I say "OK"?

I leave my wifi unsecured, and do it so if anyone comes over they can use the internet, if my neighbor jumps on it, it doesnt matter to me. My wireless is only for internet purposes, and does not have access to my network.

What you (and others) are missing is this:

When using wireless networking, anything that moves over your network is exposed to anyone else on the network. If I'm on your network I can see you log into Facebook, YouTube, your bank, email, dating sites, whatever. Every web address you type in, or search that you do.

Chat programs are another good example; most don't encrypt the chat session so both sides of a chat are exposed in real time.

Just like at a coffee shop, anyone on your wireless network could be standing over your shoulder watching what you type, and seeing what you see (or at least the raw data to reproduce what you see).

This isn't something that requires a great deal of technical prowess either; there are tons of apps on the web that make it easy for anyone to do this.

This is just one example of a simple to install app that anyone can get:

What you are missing is that if you use my wifi, you are not on my network. you can not see me log into facebook or anything else I do online, because you are not on my network. because if you are on my wifi, you are not connected to my network, you only have access to the internet.

Granted, if you and someone else is connected to my wifi at the same time, you could see what they are doing, but this still has no effect on me and what I am doing.

Can you post a link to a site that tells how to set our wifi up like that?

I don't know of any site that would show you how to do this. my set up is far more complex then most home users will ever use or need. basically I am using 2 internet connections, one is wired, and the other is wireless. My home network that all my computers use, are not on the wifi. The wifi is there just only for people to use the internet.

So you have a router connected to a router, or you are paying for two connections from your ISP and have 2 routers connected to your ISP.

What ever the case, the public IP addresse(s) are leased to YOU, and if someone connects to your wireless, sends an email threatening the life of an elected government official, guess whose front door is going to get smashed in by the SWAT team when they come to arrest YOU.
