Blockchain - Get Some Crypto Currency on an Infineon Security 2Go Card

Jan Cumps
Jan Cumps
15 Mar 2020

This post is part of the Infineon Blockchain Starter Kit road test.

Blockchain - outside of the bitcoin context - is new to me.

Follow along with me on this path to learn the technology....

 

 

Before I can fully use the Security 2Go cards in the coinfinity app, I need to have cash on at least one card. This blog shows the sequence to get fake value on the card.

image

 

 

I used the steps of the Infineon video.

 

Switch to a Test Blockchain

 

Switch coinfinity to ropsten test network via the menu.

image

 

Install MetaMask and Create a Wallet

 

Then, (I did it on a laptop): Add metamask plugin to my browser.

image

Then, when the plugin is opened:

  • create account
  • create wallet
  • Switch to Ropsten test network

 

image

 

Get a 1 ether Test Coin in your Wallet

 

Then open a new tab to https://faucet.metamask.io/

When you click on request one ether from faucet, it asks to log on to your metamask wallet and then creates a transaction id for 1 ether.

image

When you (right-)click on the transaction URL, you navigate to the ropsten test website and see the status.

image

When that page confirms success of the transaction, the 1 ether is in your wallet.

image

 

Transfer 0.1 ether to the Infineon Card

 

You can now transfer this to a card. I entered the address of my card by tapping it on the phone with the coinfinity app open,

then used the QR button on MetaMask and my PC camera to scan the QR. This worked well.

image

After some time (I chose the Slow option to prevent burning my test money), the amount was transferred.

image

 

 

 

Test if the Money Arrived

 

When I now tap that same card to my telephone with the coinfinity app open, it shows the amount, if you selected Key 1.

image

 

This budget can be used now in transactions with others ....

    I also just casted 2 votes with the app and an Infineon card using a smart contract.

    This should appear here: https://ropsten.etherscan.io/address/0x104d919b299dbbbea258a41e2e910c29c551bf17

     

    (it doesn't yet).

    I logged an issue for that on the github repo of Infineon: https://github.com/Infineon/BlockchainSecurity2Go-Android/issues/1

    It's fixed. I didn't provide enough gaz image - here's the article: Blockchain - Smart Contract Test

    So voting doesn't seem to work (I see online that the last successful vote was 60 days ago). The app gives a "vote cast" message but I haven't seen anyting arriving.

    Also my ether budget hsn't gne down, while a vote costs 0.00x ether (a small but changing price).

     

    I was successful transfering ether between cards:

     

    image

     

    image

     

    I used card#2 with key#2 as the receiving address

    My balance after the transaction:

    image

    oldest transaction was the 1 free (yet worthless) ether.

    Then I moved 0.1 of that to the smart card*, and that costed 0.000042 ether.

    I now have 0.1 on that card and 0.899958 ether left in the MetaMask wallet.

     

     

     

    * the coins aren't on the card. Not even stored on there. The coinfinity app uses the cards keys to go and retrieve the ballance of the account related to that key.
