Topic: Criptoe.Com Physical Coin thread - page 2. (Read 6405 times)
Would be nice to see a how-to video as Fuse suggested a few days ago. Also good for later buyers of the coin and info in the shop.
I was wondering if anyone knew the exact scaling when printing the QR code for the physical guldencoin by criptoe? Can't seem to find it anywhere.
Could save me a ton of paper

Thanks for explaining this. Learned something new here.
No problem, mate. I'm glad I could help.
I wasn't able to complete the hologram video tonight. The night just got away from me with the baby. I will bring a coin to work tomorrow and see if I can't do it there. I have better camera hardware/software there anyway. I'm sorry, mate.
Fuse, good to see you moved to PrestaShop.
If you're interested in in cryptocurrency module for PrestaShop let me know by PM.

A few questions about private key's. I generated a public walletaddress and a private key on guldencoinpage of https://walletgenerator.net/ as a test.
When I want to use the private key is that acting like a normal walletaddress and acting for sending coins from the public address? It has way more numbers than the normal addresses. And how to import it in the windows client. Maybe silly questions, never worked with private keys

Each address you generate has a public address and a private key. The private key is what is used to import the public address into the wallet program.
I would recommend doing this on another computer or using a live linux CD. You don't want to muck up your main wallet with additional addresses. Additionally, in terms of security, it's better to do this on a system that can't be comprised. When you open the wallet, you click on help->console. In the console you type the following:
importprivkey [the private key] [wallet label]
For instance, this would be an example:
importprivkey 6a7pr11YST2obTrYe7kY2TTURuaQUKBFXwoCbWECBmfmejVDbZT MyCoinWallet
That will add that wallet and allow you to check the funds or spend them. However, you don't need to load the key into the wallet program to add funds to the wallet. You can generate an key pair, then send the coins to the public key. However, I would recommend practicing with generating and adding keys to a wallet first. One day you'll probably want to be able to pull the coins out or sell them, so you'll want to be able to get to them in the wallet program. If you ever lose the private key, you can't access the wallet, and those coins will be lost on the chain.

Recieved my coin today, very pleased!
I'll work on the video as soon as I get home.
Take your time. No hurry
If needed, I can post a video of how I do it when I get home tonight.
Would be nice
Also the two-factor key, how that can be done.Thanks for the great coins! They look fantastic.

As far as the two-factor key goes, I just mean using any security measure that allows you to not have to store the private key with the wallet address. That could be a brain wallet mnemonic, or an encrypted key, or even a split key pair(half the key with the coin, and the other half in a secure location). It's an added level of security to the cold storage options.
Additionally, it looks like cryptolife has changed recently. You can create a keypair at https://walletgenerator.net/ as well. You can also do it via the wallet console.

Use of the hologram stickers:
I have included 2 stickers in with each coin. This is in case you totally mess up putting it on or the first sticker gets tweaked somehow. Either way, it's pretty straightforward. There is a clear square in the middle of the hologram that will line up with the indent on the back of the coin. You need to create a paper wallet key pair, and print it out on a paper no wider than 0.5" in one dimension. It can be longer in the other dimension because it can be folded over. See this post for more info on the wallet:
Additionally, you could use a qrcode, as long as you have a printer capable of high resolution at smaller sizes. I was able to scan a wallet address as a QR code at a 0.5" x 0.5" size. I haven't tested Bram's QR code generator with the added NLG image, but I think that would be even cooler. You can find it here: http://guldencoinqrcode.nl/.
You could also just print the wallet address, and then keep the private key separate. That way if you lose the coin, you never lose the digital coins loaded on it. You could also do a two-factor key pair... it's really all up to you how you want to "load" the coin.
Once you have the paper wallet, I found it was easier to attach the paper to the hologram first and then attach the hologram to the coin. I placed the hologram sticky side up on a flat surface and then carefully placed the paper on the sticker, aligning the sticker with the clear square in the middle. Once the paper was attached, I used a paperclip as an applicator of sorts to put the sticker on the coin. I didn't want my fingerprints to transfer to the sticker, or the oils on my hands to get on the coin. So I pressed the paperclip against the sticker while it was on the table, and then I was able to pick up the sticker without handling it directly. It also made it easier to place the sticker on the coin because my big fat fingers weren't in the way.
For reference, this is what it would end up like:
It's hard to write a good description of how I did all this, but I hope that helps. If needed, I can post a video of how I do it when I get home tonight.

See this post for more info on the wallet:
If anyone is wondering about loading these, I would like to note that I will not personally load them. I want the end user to load it themselves. This is more secure, and it takes a key issue out of the equation - losing digital coins if the physical coin gets lost/stolen in shipping. Additionally, I don't want to be responsible for making 250 wallet/pairs that could be claimed I still have access to. More secure IMO.
For those of you that want to know how the key pair could possibly look, I made one in Illustrator with a wallet generated from Cryptolife.net. It's 0.5" x 1.5", and would be folded accordion style into thirds. The space on the coin for the pair info is 0.5" x 0.5". The font used for this pair was 7pt, and it is perfectly legible when printed on a laserjet printer. I don't have an inkjet to test with, but I'm sure you could get similar results. Here it is:
FYI... thats a throw-away address, and no one should use it as it's now public.

Got the coin, very cool, big and heavy, just need some help with putting in the hologrom and qr code
Sorry for the delay in that post... got wrapped up with my buddy digithusiast in the main thread. Oh, the joys of being hated for no legitimate reason lol.
I will double post to keep the info clean.
