... LiteCoinGuy I went to take a look at their website: digitalbitbox.com, looks like an interesting product! I like the use of the chip (like Ledger I suppose), I also like the fact that they say it will be simple and that there will be no firmware updates. Both my Ledger Nano and Trezor are asking me to update firmware... I look forward to finding out how much it will cost and become available. |

Would anyone here buy a disposable hardware wallet that is programmed ONCE, and then cannot be programmed with a different private key. Instead, you just toss it and buy a new one if you want a different address. It would only have a single address, but I could still see this having some use. It would only cost maybe $5 per wallet, so you could have 5 of them for pretty cheap, and then just get a new one if you need a new address (they wouldn't be HD, obviously). It would be like the old paper wallets, but way easier and more secure to spend from. Would anyone buy it? Update: Join the discussion here: https://bitcointalk.org/index.php?topic=1096923.0 |

How can I use this card then?
You go to your local Bitcoin merchant, touch the card to his phone and give your PIN code. The third time you go to the same merchant no PIN code will be required and you can simply swipe your card like Will Smith did in I, Robot. (Don't worry it's still safe as there are various checks and limits in place) If he/she does not have the required app show him/her the QR code on the front of the card. Tell him/her it will make the Bitcoin payments faster, easier and more robust against internet interruptions. (For the moment this is for NFC enabled Android phones only) Doesn't that limit the usage of this card? I'm not entirely sure which part you refer to. Of course with a fully open source protocol and terminal app one way or the other I expect an IPhone app down the line - eventually even purpose built POS systems. |

Fidesmo is considering offering open Yubikey Neos on which you'll be able to download your own Java Card Bitcoin Hardware Wallets or buy one. Two implementations are already available : Ledger and SatoChip - I'd also be interested to add a Java Card implementation of BlosTech's design on our wallet. If you're interested (everyone should be  ) just let them know

My card's code is not in Java unfortunately (ZC Basic), but anyone is welcome to build a java implementation on the protocol - I was hoping/planning for a diverse ecosystem when I designed it  |

Yes I browsed it very quickly, some points are still not clear (confirmation of the change, confirmation code ...) but I'll make a more detailed post after spending more time on it. Thanks for the effort and publishing it already.

Ah yes that is true. However only 64% of Americans even have a smartphone of any kind. A smaller number have internet access and a mobile camera on their phone. Maybe 50% of Americans have both. Then some of this number will not have the technical skills to use apps. So my card has a larger potential market than all mobile wallet apps... and that is just the wealthy tech savy Americans, the numbers will be even lower for 2nd and 3rd world countries. With my system only the merchant needs a smartphone. + my system is more secure and faster than a mobile wallet (because my app can see the TX while sending it). My system can also work during periods of no internet connectivty what-so-ever due to card side caching of TX data. Everything has limits, I'm quite happy with mine |

That price range is very reasonable, I hope that it is priced so. As a general rule, simplicity is something I admire and like in such products. Firmware updates are not only a hassle (mild, we hope), but introduce risks, I believe some people had problems with a Trezor firmware update (I did not do the update).

simplicity is king and it should be cheap. i would like to see a wallet for 5 - 8 € in one or two years. that would be a good way to secure the coins of alot of people.

In addition to this, this will lead to mass adoption of hardware wallets which u feel is quite necessary. The HW1 has done quite a good job on the price. Though, I'm anticipating cheaper hardware wallets :d |

You can check in OP about the status of development. Ledger Blue is under development. -snip-
i would estimate that it will cost 20-40 Euro/Dollar. no firmware updates would be cool indeed. That price range is very reasonable, I hope that it is priced so. As a general rule, simplicity is something I admire and like in such products. Firmware updates are not only a hassle (mild, we hope), but introduce risks, I believe some people had problems with a Trezor firmware update (I did not do the update). "A BTC wallet for the rest of us!" Not always. Sometimes updating firmware are mandatory. For example, if a flaw is found, you should update firmware to prevent any possible attacks. If it doesn't allow firmware updates, you will need to buy a new one with latest firmware if such a thing happen. IMHO making firmware update as optional is better than no firmware update. |

... Well, I hear you, M.Z. (re sometimes firmware updates maybe being necessary), but I would think that some companies could design and make a cheap & reliable hardware wallet that would never require any updates. OK, I do not program, but would it not be possible to design a device and write bulletproof software for a simple device? Simple, reliable, tough & cheap: is that too much to ask? |
