EmerSSL InfoCard is a decentralized distributed "business card" system on the Emercoin blockchain that complements EmerSSL's passwordless logins, allowing website profiles to be automatically populated. InfoCard has the ability to organize information in a hierarchical structure, which can be useful for quick content updates to all cards within companies or other organizations.

InfoCard is a kind of "business card system on the blockchain" that contains information about its owner, such as email address, phone number, date of birth and so on. InfoCard can be used on sites with EmerSSL authorization to automatically populate account details, This means that rather than entering personal details every time you create a new online account, you can provide your InfoCard virtual business card to fill in the data.

  2. Next, rename the file in to infocard_<your_login_name>.info and change the data to your own. If you prefer not to provide data for some things, just remove the line. Sample data:

  3. Go to the X509 folder and run

    $ cd downloads/X509
    $ ./ infocard_<your_login_name>.info

    In Windows, run by double-clicking the file info_crypt.bat and enter the InfoCard name:


    If all goes well, the output will contain a message like this:

    Please, deposit into Emercoin NVS pair:
    Key: info:e120319a479f4ac4
    Value: body of the file: infocard_<your_login_name>.info.ze
    To link your EmerSSL certificate to this info file, run ./ and use value for UID: info: e120319a479f4ac4:      ac7c3821f171b6a8bd8cd33d829f5b

    Please note that this information is not stored anywhere, so it is advisable to keep a record in a text document.

  4. The next step is to import the business card to the network. To do this, open your wallet and go to the tab Manage Names. In the Name box, copy our Key, info:e120319a479f4ac4. In the Value field, paste the contents of the file *.ze, which should be in the scripts folder. The contents of the file will look like gibberish - and should, this is normal. The New address field should be left blank.

    Click submit and you're done!
