Use our API, callbacks, and the on page payment button. You'll need to modify your Wordpress shopping cart.

How can I use Inputs to accept Bitcoins for digital downloads on my Wordpress shopping cart? I don't want to use Bitpay I'd rather process all the orders myself.

Basically user goes to my web site, adds digital products to there shopping cart, they pay in Bitcoins and once the transaction is confirmed a download link will appear on the site or will be emailed to them

Transactions with amounts less than 0.01 BTC don't generate emails.

Some problems with your mailserver?

I did not get the default notification mail for transactions io48cc085fc067fb4999d13a23d66460efec8cf5219b8f0c0ec6e4cd14440454 and io4494913ebbb95aec48ae1acfa7560decec2c0108d89f9db2b6408c388d095c

It was only worth 0.01 BTC

Doesn't protect against MITM attacks.

I know but the wallet provider would lock it after so many bad tries.

Bruteforcing 3 numbers (24 bits) isnt that hard.

An idea that's been brewing since reading about how txtbitcoin handles OTP....

A bitcoin "pin card" as a non-technical, physical, cheap, portable solution to Bitcoin security that
wallet providers can use.

It's some type of paper or plastic card that contains a grid of 3-digit pin codes.
Perhaps laid out in this way for convenient printing onto credit card size cards:

      1   2   3   4   5   6   7   8   9   10
   0   356    678   355   843   356   313  121   134   662   345
   1   245   245    239   458   848   245   428  242   472   198
   2   221   503    etc
   3   
   4
   5
   6
   7

Then the person could look up numbers easily so "17" would be correspond to "428"

Important parts:
-the codes all derive from some type of publicly known algorithm using a seed
-the seed is packaged with the card but is separated so the person can safely store the seed somewhere safe
-the seed also creates private keys and bitcoin addresses!
-open methodology for making them so anyone can create their own bitcoin pin card and all they will have to
do is upload the seed to the wallet provider
-if the wallet provider makes the cards there is little chance anyone can steal the codes as they were never transferred over
the the internet and the wallet provider has stored all the seeds when the cards were made
-if a card is lost or stolen the funds can be moved somewhere else using the seed
-it allows for someone to use the online wallet without registering!


What the user will see:
-a simple card with codes and a user number at the top along with address that can be used anytime for funding the account
-the user numbers could be grouped based on provider. We could have inputs.io wallets for example
always start with 001. This way as different wallets adopt the cards they can transfer across providers using user
numbers and not bitcoin addresses.
-the bitcoin wallet provider keeps track of each user number and the card it goes with
-the user number is just so the user doesn't have to type firstbits or addresses into a phone every time


-Bitcoin pin cards are meant for when someone else is hosting a wallet for you and want better security.
We can now use unsecured channels to communicate without worrying about losing funds!

SMS
-phone numbers can be spoofed or spied on which makes it hard to send BTC securely with SMS
How the card could work: we could text "to (usernumber or address) 0.1 from (usernumber)" to a wallet provider. They would then text you "17".
The person now looks that up and sends back "428". A correct reply will cause the 0.1 to send.

Email
-by emailing the wallet provider "to address 0.1 from usernumber", we would get an email back with "18" and we just have to
reply just like in the sms example

-it could even work for using 1-800 number automated machines

-the wallet provider could also lock the account after a set number of failed codes and the only way to unlock it, is to find the seed that was stored somewhere else
-as the pins run out the person is encouraged to move funds to a new card before it "goes back to 1" or the first code


Is it a good idea?

I think it could provide a simple secure way of using sms, email, phone, to sent BTC and internet or a computer isn't even required!

Ok thank you for the response. I thought because the previous transactions where done off chain there might be some delay when transferring to a Blockchain wallet.

No.

Why would there be a delay?

So if I send coins to a Blockchain account from Inputs there won't be a delay?

Inputs moves the coins around between its many different public addresses. While coins sent to your deposit address will always end up in your Inputs account, the coins don't necessarily stay there and when you send coins from your Inputs account to some other address, the coins can come from any of the addresses controlled by Inputs. So you can't use tools like Blockchain.info to check how much there is in your Inputs account.

I have a question when I check my inputs wallets address balance on Blockchain it shows me zero balance even though I have money in my Inputs account. Sometimes it will show a much smaller balance is that normal? Also if I send money to a Blockchain address from Inputs will there be an issue since the inputs transactions weren't charged the .0005 miner fee?

Ahhhh.. One step late on the voucher

Fixed.


Vouchers can be generated in the send tab. Here's one: 5f0a932b84a01467471c8839

TradeFortress, let me start off by saying, inputs.io has made my BTC wallet life so much easier. Thank you.


Now, where, how, when can I find voucher codes? ^_^ Feel free to PM if you don't want to tell the world

the unconfirmed refresh thing seems buggy.

after I hit refresh it shows the unconfirmed amount, however, after some time it swaps back to 0. I have to refresh again to see the unconfirmed amount

Thanks for the quick reply!
