Every credit card specifically says on the back that it's not valid unless signed, and as an employee I was instructed by Mastercard and my manager never to accept an unsigned card (or one that says "See ID" or whatever). So I didn't.
To the best of my knowledge, no major credit card companies allow the use of copied credit cards.
It varies. A lot of retail workers won't care, but some will. Especially the ones who are smart enough to be aware of credit card fraud but not so knowledgeable they know about Coin.
I don't think someone would have to be turned down from a purchase many times before they threw the thing in the garbage. It doesn't have to happen often.
All the major credit card companies will be rolling out soon-to-be-mandatory chip systems for their credit cards. The point of this chip is specifically to prevent copying of credit cards. Coin is dead in the water.
Beyond this, how many register monkeys will decline the transaction because it's not the original card? I was trained at my old retail job by an actual Mastercard representative never to allow use of a credit card without a signed back, much less a card that's literally a personal copy.
Realistically, "Internet Explorer" as a standard is at least as important as whatever other "standard" you're using. Especially in corporate environments, "Internet Explorer" is generally the standard.
You can find a lot of people that SAY they want these things, but no one buys them. Pretty much all of the slide-out keyboard phones have been commercial failures.
They're talking about purchase and installation:
"Because less modules are needed for the same power output, less land, labor, mounting structures, wiring and support racks are also required, saving an estimate of 10 cents a watt for every point of efficiency gained."
So if you're installing 4000 watts worth of panel, using 23% efficiency panels costs $400 less to purchase and install than 22% efficiency panels.
I was under the impression that Tesla vehicles used banks of off-the-shelf 18650 Li-ion batteries. Panasonic is their current supplier if I recall. Even their proposed battery plant in the southwest is really a place for Panasonic to manufacture batteries for Tesla. Yes, they package them well and I'm sure they have some great controls and associated hardware and software, but is there really something groundbreaking about their batteries specifically? They already make a powertrain for Toyota - a move that hasn't produced a fraction of the buzz and money as their own vehicles. Not sure I understand this suggestion.
No worries. The EPA has you covered:
You'd think it would take more than a simple majority to secede from your country.....
For one thing, this isn't USPS. It's UPS. I expect the laws are different for that.
For another, the part apparently wasn't addressed to him. It was misdelivered. If someone else's mail ends up in your mailbox, you don't get to open it and keep whatever's inside. If it's not addressed to you, you're not allowed to open it at all.
Um, no. The Air Force gave Russia the contract with zero bidding process. SpaceX literally never had a chance. They're suing for a level playing field where they could bid against Russia in an open process.
The rest of your post is...... well.
You can't print stamps using that service. You need to actually purchase stamps, or have an account from somewhere like Stamps.com or Pitney Bowes.
There are a number of things that require it. For me the big ones are MLB At Bat, WatchESPN, Hulu, and HBO Go.
