There's no reason to build on top of failed convention. PIN numbers are ==! FTW

2 FA, that's a little more promising. Bio-metric scanning, even better. The sky is the limit on security measures.

I believe consumer financial products should have as much security as the user wishes, and no financial product should be secured by a 4-6 digit numeric password, besides those holding less than a hundred simoleons


briehost, while those are certainly cool ideas, they are not realistic for getting Bitcoin implemented in the modern day economy.
(Also, bio-metric scanning would take away from the valuable privacy of Bitcoin.)

Unfortunately, cost and adoption is the limit on security measures.

To do what you are suggesting would require terminal manufactures to start making these units, and distribute them. You are talking about a huge scaling.
It will not make sense for a terminal manufacturer to do this for Bitcoin with such low adoption; if anything, it would first need to be adopted by the credit card companies, then Bitcoin.

Right now, terminals cost $100-$400 wholesale. A high tech solution like you propose would cost start at $800 wholesale, huuuuge price difference and merchant's would not want to change out all their terminals, just for Bitcoin. (Avg. merchant has 3 terminals for different lanes.)

Agreed, security ain't what it should be. But right now the goal is mass adoption of Bitcoin, not to rewrite the security protocols of digital transactions.

Okay, seriously, couldn't a corporation similar to a Building Society hold your Bitcoins off-the-chain for things like debit card payments? Much easier than having your private key exposed, and it's pretty safe.


You could, it's just not necessary and just invites problems.

Private key would not be exposed with encrypted debit chip, as it is not with current chipped debit cards.
723  Bitcoin / Bitcoin Discussion / Re: Bitcoin credit cards? on: October 01, 2013, 07:51:03 PM

Indeed. It is one thing to use a debit or credit card where the bank takes most of the fraud risk. It would be another thing to use some sort of bitcoin card where the person who ends up paying or sorting out the mess if it goes wrong is me.


So instead you want a private company like Mt. Gox to hold your hand if anything bad happens?

What happened to self responsibility.




Making a Mt. Gox like company in charge of chargebacks and disputes is an accident waiting to happen.
You are basically putting that private company at huge risk of having funds seized or stolen.
Then you want to rely on them for chargebacks??? That's madness. You are giving a private company, without any oversight, the ability to manipulate transactions. They can steal merchant's and consumer's money using the chargeback model. It's ridiculous.

Just dont use Bitcoin Credit Card for risky transactions. Use it when buying a coffee. Use it when buying groceries. Use it when buying furniture. Don't use it to order things online or over the phone. That simple.

Essentially what is being suggested is a scenario where you tell each and every merchant that you do business with where you've stored a big box filled with cash.  You continuously add cash to this box as needed.  The merchants then go to your box of cash and remove the amount that you've asked them to remove for payment of whatever you are purchasing.  You agree not to move the box at all, and you trust (hope?) that the merchant will never use their knowledge of the location of the box to go take additional cash that you haven't authorized no matter how desperate they become.

And this is being offered as equivalent to the current credit/debit card security.

You can see how when you think about bitcoin as a currency instead of a payment network, some of the concepts start to fall apart.

I fail to see your point.

Why is the technology used for debit transaction using encrypted PINs, NOT good enough for Bitcoin?

It's been used on a scale at least 1,000 X larger than Bitcoin, and has succeeded. Why reinvent the wheel?

A network is only going to be as secure as the users using it.



Quote
You aren't paying attention.

No, you aren't. Just because you were covered on your theft, it is not the rule.

"A major factor in consumer protection is the card company’s liability policies. Federal law limits consumer liability for unauthorized debit payments to $50, if the consumer reports the fraud within two business days (the cap goes up to $500 if the report is not timely [2 days!]). This means that the consumer has to pay $50-500 dollars before the card company will cover the rest. Major card companies like Visa and MasterCard have “zero liability” for unauthorized transactions, meaning that if the consumer meets the requirements, they don’t have to pay anything and are reimbursed.

However, this “zero liability” only applies to signed transactions. Every company seems to have their own policy when it comes to PIN-based transactions. MasterCard does not extend zero liability protection to PIN purchases, while other financial institutions do. For this reason, it’s important to check the policy on your debit account. Check the back of your card to find out which networks handle your transactions (ex: the Star network), and then call your bank to find out if you qualify for more than just basic federal protections."

Where is the risk? If you use your regular debit card at a terminal location, like a gas pump, in which a thief has installed a skimmer and a videocamera to record your PIN number, you will not get your money back.
- snip -

Of course I will.  I have.  I speak from personal experience.  That is the purpose of the insurance that the banks and processing companies provide.

The "insurance" you speak of does not exist.

The only thing credit card companies and banks offer is chargeback protection.

It can only be used in the event of:

1. Straight card theft. But not when PIN number is used! Banks will NEVER NOT ALWAYS give you money back when your correct PIN is used.
2. Non-receipt of goods. For mail orders, delivery of goods.
3. Broken or non-working items. If you buy something and it stops working. Time limit on this.
b. Overcharging

...And all this does is start the chargeback process. The merchant is given the opportunity to write a letter of explanation and provide documentation of their side.

If what you are purchasing could be better covered by a credit card for the above three things, by all means, use a credit card. For everything else, There's Bitcoin Credit Card Smiley




That said, Bitcoin credit card would not be ideal for buying goods on the internet or over the phone (duh, just do it given the tools already available), or any kind of purchase where you do not receive the goods or services right away.

Quote
The best thing about having a BTC Card would be that you liability would be limited to however much you'd want to put on the card. You could keep a few extra bitcoin on your phone in case of emergency. Everything else can be left in your armory client at home.

Exactly!
No reason to go bananas and expect a crazy amount of security in regards to the Bitcoin Credit Card, just put as much on it as you want.

No, the whole idea of Bitcoin is take away the middleman (the banks!) from the equation.

No banks are needed for my proposal.



Why create a centralized system for a fundamentally decentralized system. It makes no sense.



What you propose is possible, but it involves a private company basically acting as an exchange like Mt. Gox, but with the ability to communicate with terminals and POS systems and new debit cards. You are then putting all the risk with this one private company.

Hacker wipes them out, you're done. Government intervenes, you're done.

I do not want to use a credit card in a Mt. Gox-y sort of way. THAT is too risky!
729  Bitcoin / Bitcoin Discussion / Re: Bitcoin credit cards? on: October 01, 2013, 06:51:53 PM
To break it down, when the customer enters in the PIN number via the terminal, this "unlocks" the Bitcoin address private key to proceed with the transaction. The transaction amount displays on the terminal screen, and the customer presses OK if it is correct. Simple.

So the machine -- 'PCI Compliant' or not -- signs the transaction with your private key, which you have exposed to it using your PIN? No thanks.

About the day after this gets introduced, somebody is going to create look-alike terminals that send your private key to haxxors in the Ukraine. How would one be able to tell you're dealing with an actual, non-nefarious terminal?


Really? Like seriously?

Then you might as well never use a debit or credit card terminal ever again. Let me know how that works out Cheesy

Sorry but this is the real world. If you are that paranoid just stick to cash Tongue


How would one be able to tell you're dealing with an actual, non-nefarious terminal?
If you go to a legit store, you will be dealing with a legit terminal.

If a business uses anything compromised like what you are describing, the FBI and or Secret Service gets involved. (Yes, Secret Service investigates credit card fraud).

True, I was thinking about this last night and the best solution would seem to be built in PIN like the debit cards used in Europe and Canada.
"Chip debit cards encrypt all information stored on them, increasing your safety when completing a transaction."

This will prevent merchant from having ALL your info just on the magstripe.

I still don't understand how this will work.  The merchant can't move the bitcoins from your address unless they have your unencrypted private key.  Once they have your unencrypted private key, there is nothing that prevents them from saving it and re-using it in the future.

It seems that what is needed is a card that has a processor, display, and input interface built into it, the card would be placed with some sort of electrical contacts interfacing with the merchant's terminal.  The terminal would request the bitcoin addresses known by the card.  The terminal would then search the blockchain for unspent outputs associated with those addresses.  The terminal would build an unsigned transaction and submit the transaction to the card requesting a signature. The card would then display the transaction amount on its built in display.  The card owner would verify that the displayed amount was correct, and would use the card's built in input interface to indicate acceptance.  The card would reply to the terminal with a signed transaction.  The terminal would then broadcast the transaction to the bitcoin network.

Patience, my son.

That's what the chip debit card is for.

Once you insert your card in the terminal, the terminal prompts the customer for their PIN number. The customer inserts their PIN number into the terminal. Since all terminals are PCI compliant nowadays, the inputted PIN is encrypted and cannot be recorded by the merchant or anyone else. This is all done now with Canadian and European debit cards, this is not just theory.

To break it down, when the customer enters in the PIN number via the terminal, this "unlocks" the Bitcoin address private key to proceed with the transaction. The transaction amount displays on the terminal screen, and the customer presses OK if it is correct. Simple.

I worked for many years in the credit card processing industry, so I know about these things. To be honest, I'm surprised this hasn't already been done. If people want to join together to do this, let's go for it Wink


733  Bitcoin / Bitcoin Discussion / Re: Bitcoin credit cards? on: October 01, 2013, 03:52:09 PM

The problem is that bitcoin is a push system. If the shop can directly charge bitcoins in your adress if because they know your private key... so the also could charge all the money they want in the future. Makes no sense at all.
You need some kind of bank or intermediate.


I talked to someone on the BitCoin Convention with a great idea. You can store Gold, Silver and BTC on a credit card and it only gets converted to cash if you use the card. That way you always get the most recent price.

This is a great idea! But only if they offer a legit change Tongue

Again, no need for a central bank Smiley

This is pretty simple.


Bitcoin credit card's mag stripe is encoded with your Bitcoin address.


Each merchant (brick and mortar store) has a pre-configured terminal ready to accept Bitcoin along with credit and debit cards.

Merchant rings you up on their POS System (point of sale system) with the Bitcoin enabled software, that than processes the mag stripe Bitcoin address, ringing up your scanned items.

Amount shows on the terminal for your approval (much like a debit transaction). You press Yes (green) to accept, or Cancel (red) to decline.
Perhaps a pin code could be added somehow, this would be very hard to implement universally though, and I don't think it would be feasible, at least not at first.

Customer hits OK and transaction goes through, debiting their Bitcoin address.

Receipt prints out and shows available balance in BTC and USD.

---


So, right now three things are missing:

1. The physical Bitcoin card, featuring encoded BTC address on the magstripe. (Easily achieved with common Magstripe encorder, $200-250). For the MacGuyver types, you can even overwrite the magstripes of existing credit cards or even drivers licenses.

2. Software to convert the read mag stripe BTC addresses to work with existing or new POS software, which can interact with the BTC network. This is for the merchant side of the transaction.


A special build for the terminal would have to be written. Actually, a build would have to be made for every single model of terminal that would want to be used.
By focusing on the ten most popular terminals, this can be achieved without being insurmountable. Companies like TSYS specialize in writing code for terminals and regularly update existing builds.


This is a credit card terminal.

When you get to checkout the cashier asks you how you are going to pay. Right now they ask, "Cash, credit or debit?"

Tomorrow it will be: "Cash, credit, debit, or Bitcoin?"

Smiley


Technically, no this is not a credit card since it does not extend credit, more a debit card if anything. It's really a representation of your BTC address in a mag stripe form, that can be carrier around and easily used for transactions the same way a credit card can be used.

Great website, awesome idea.... but where's the profit??

You have processed $46,000.

If you charged even, 2%, that would be only $920 in gross.

My assumptions:
It says you've had 6K hits since April, not bad, but assuming you got you majority of your profits in the last month or two, it's only making $400 in gross a month.

That's $4,800 a year gross.


And that's not accounting for your the cost to run the site and any fees the third parties charge for bill payment services to you.

And also, I noted on your site you are advertising 0% fees (up to $9,000). So the $46,000 you have processed so far has only been for 0%?



Bottom line: How much profit did the website generate last month?

I have been extremely surprised at the lack of movement in the price of Bitcoin for the last 1-2 months... I don't really think the US govt shutdown is really going to drive the price up at this point.


If the stock market really has a conniption tomorrow BECAUSE of the shutdown, then it may cause a small increase in BTC.
