Transfer some funds or shares to your Investor Card.
1. Setting up your Investor Card
When you first receive your Investor Cards, they will be in a blank state, i.e. they will not have any Ethereum wallets on them. You will first need to create an Ethereum wallet by using your first card, and then create a backup of it using your second and third card.
The Investor Cards are exact copies of each other. You can choose either one as main card or backup.
To create and backup a wallet on your Investor Card, you will need the official Tangem app (see below).
After installing and launching the app, you will be greeted with an intro screen. Tap "Scan Card" and scan your Investor Card as shown in the animation.
If your card has been scanned successfully, you will be asked to create a wallet on it. You will need to scan your card for a second time while your Ethereum wallet is being generated.
After you see the Success screen, you will be given the option to add a backup card. Do not ignore to create a backup. If your card gets stolen, damaged or starts to malfunction, a backup card is the only way to recover assets from your Ethereum wallet.
You will also be required to setup an access code. Much like a debit card, the access code will be needed whenever you want to approve any operations from your Investor Card. Choose a simple code that you will not forget.
During the backup process, a copy of the first card will be generated. These cards will have the same Ethereum address stored on them. A good idea is to use one for regular operations, while keeping the other two somewhere safe to prevent theft and damage.
If at any time, for any reason, one of your cards starts to malfunction, immediately use the second card to move any assets on your cards to another Ethereum wallet. Tangem cards are durable, and even one of them malfunctioning should be a very rare scenario. However, if all of the cards start to have problems at the same time, you will not be able to access any assets stored on them.
2. Importing your Investor Card into the Aktionariat Portfolio App
This will link the newly generated wallet to your Aktionariat account. The Investor Card will appear under your Ethereum addresses and you will be able to track assets on it.
The Aktionariat Portfolio App will be able to sign messages and transactions from the imported Investor Card address, without ever gaining access to the private keys or seed phrases.
You will need to confirm any actions by scanning your Investor Card with the Aktionariat Portfolio App. The Investor Card will sign your requests and the Aktionariat Portfolio App will execute the signed transactions.
Make sure you have the latest version of the Aktionariat Portfolio App before attempting an import.
Now go to the "Connect" tab in the app and select "Import an Address". Select "Import Investor Card".
In the first screen, tap on "Scan Card" and scan your card. Enter your access code when you are asked. The Aktionariat Portfolio App will check for the correct wallet setup and detect the Ethereum address on the scanned card. You may check that this address matches the address you see in the official Tangem app.
In the second screen, tap on "Import Card Address". This will ask you to scan your card for a second time, to generate the necessary signature for adding the Ethereum address to your portfolio.
Upon successful completion, you will see a confirmation message. The newly added account can be found under "Ethereum Addresses" in the "Connect" tab. It should be marked as "Investor Card".
Using your Investor Card
The Aktionariat Portfolio App recognizes that, although the private keys of this Ethereum address don't exist on your mobile wallet, transactions and messages can still be signed from it in tandem with the Investor Card. You will be able to select the Investor Card Wallet to connect to the Brokerbot or for sending outbound transactions the same way you were able to select any imported account. As a difference, signing from imported accounts are automatic, while signing from the Investor Card wallet will require scanning your card and entering the access code every time.
