Fewer verification requests
Employers, landlords and partners no longer need to phone or write to you to confirm a certificate. Your signature on the card answers that question.
Issue cards that others can check without calling you
Your organization already confirms facts about people: degrees, memberships, employment, registrations. Today that means letters, stamped copies and phone calls from third parties. With Bisotun you issue a digitally signed card once, and anyone who receives it can verify it themselves.
Why issue Bisotun cards
Harder to forge
A card signed with your key cannot be altered or imitated without the check failing. A service that checks your card cannot be fooled by an edited copy or a fake letter.
Less paperwork for everyone
No certified copies, no stamped letters. People receive the card straight into their wallet and use it as often as they need.
Respect for privacy
People share only the items a service asks for. And you are not contacted when your card is used, so you do not end up holding a record of where people show it.
One card, many uses
The same membership or diploma card works with every service that accepts Bisotun, without separate integrations per partner.
In your people's language
Card names and descriptions are shown in Persian, Arabic and English.
Examples
A university issues diplomas
Organizations can issueBefore
Graduates request certified copies; the registrar answers verification letters from employers for years.
With Bisotun
At graduation, each graduate scans a QR code in the student portal and receives a diploma card with institution, degree, field and year.
What is shared
Whatever an employer asks for and the graduate approves, typically degree and institution.
What stays private
Grades and student number, unless requested and approved.
An association issues membership cards
Organizations can issueBefore
Plastic cards, printed lists for partner venues and emails asking "is this person still a member?".
With Bisotun
Members get a membership card with level and valid-until date after logging in to the member area.
What is shared
"Member" or the level, as the partner requests.
What stays private
Member number and contact details.
An employer issues employment cards
Organizations can issueBefore
HR writes and signs letters for rental and loan applications, and answers phone checks.
With Bisotun
Employees receive an employment card with employer and "employed: yes", renewed regularly.
What is shared
Employer and employment status.
What stays private
Salary, role and personal details.
What you define
The card
A name, a short description and a logo, in Persian, Arabic and English, shown in the wallet.
The items
The facts on the card, for example "degree", "field", "year". Prefer ready-made answers such as "over 18: yes" where a yes/no fact is enough, so people can prove it without revealing more.
The validity
How long each card stays valid (by default about six months). Choose short periods for facts that can change.
Who receives it
You decide whom to issue to, after checking them in your own way: a login to your portal, a desk visit, an existing record.
How to become an issuer
Onboarding is done together with the Bisotun team today:
Contact us
Write to support@bisotun.app with the card you have in mind and who will receive it.
Define the card
We agree the card's items, texts and logo, and add it to Bisotun's signed list of issuers and card types. Wallets download the updated list automatically.
Set up signing
Your card type gets a signing key on the Bisotun session server, and your back end is registered with permission to issue exactly that card, authenticated with your own RSA key or a shared secret.
Connect your back end
When a person is entitled to a card, your server sends a signed issuance request. You receive a link or QR code to show them; they accept the card in their wallet.
Go live
Services registered with Bisotun can be given permission to ask for your card, and they only receive it with the holder's consent.
Your back end can also ask a person to show a card they already have before you issue yours, for example a verified email address before a membership card.
Honest limits
- No early withdrawal yet. You cannot cancel a card before it expires. Use a validity that matches how quickly the fact can change, and reissue regularly.
- Card layout is fixed once issued. Items cannot be removed or reordered on a card type that is in use; a changed card becomes a new card type.
- Onboarding is manual. There is no self-service issuer portal; the Bisotun team sets up each issuer.
- Android only for now. Your card holders need an Android phone; an iOS version is planned.
