What are open badges, and why should event organizers care?
When an attendee walks away from your conference or workshop, they take knowledge, connections, and memories. But unless you give them something they can show the world, that experience disappears the moment they step out the door. Open Badges solve that problem in a technically rigorous, employer-trusted way.
An Open Badge is a digital image file, typically a PNG or SVG, with structured metadata embedded directly inside it. That metadata tells anyone who inspects it exactly who issued the badge, who earned it, what the badge represents, what criteria were required to earn it, and when it was awarded. Because this data lives inside the file itself (not just on a linked web page), the badge is inherently portable: a recipient can upload it to LinkedIn, add it to their resume, embed it in a portfolio, or email it to an employer, and the credential remains verifiable regardless of where it ends up.
The standard is maintained by 1EdTech (formerly IMS Global), an education technology standards body, and it has been adopted by thousands of organizations, from universities and professional associations to government agencies and, increasingly, event organizers who want their events to carry lasting professional weight.
The open badges standard: a plain-language technical overview
Understanding the technical foundation helps you make better implementation decisions. You do not need to write code, but knowing how the standard works will help you choose the right platform and set appropriate expectations for your attendees.
The three core objects
Every Open Badge is built from three interconnected objects:
- Issuer Profile, describes your organization: name, URL, contact email, and a unique identifier. This establishes who is making the claim.
- BadgeClass, describes the badge itself: its name, description, the image, and the criteria required to earn it. Think of this as the badge template.
- Assertion, records a specific award: who received the badge, when, and optionally what evidence supports the award. This is the individual credential.
Together, these three objects create a chain of trust. When a recruiter or employer clicks "verify" on a badge, their platform fetches these objects, checks that the assertion points to a real BadgeClass, which in turn points to a real Issuer Profile, and confirms the data has not been tampered with.
Open badges 2.0 vs. open badges 3.0: What changed and why it matters
The Open Badges specification has evolved significantly. Most platforms in production today support 2.0; forward-looking platforms like IssueBadge.com also support the newer 3.0 standard. Understanding the differences helps you decide which version best fits your event's credentialing goals.
| Feature | Open Badges 2.0 | Open Badges 3.0 |
|---|---|---|
| Underlying standard | JSON-LD (linked data) | W3C Verifiable Credentials Data Model 2.0 |
| Verification method | Hosted (server must be live) or signed (JWS) | Cryptographic proof (Ed25519 / BBS+ signatures) |
| Offline verification | Partial (signed only) | Yes, fully offline-capable |
| Decentralized identity (DID) support | No | Yes |
| Selective disclosure | No | Yes (with BBS+ signatures) |
| Backward compatibility | , | Designed to coexist with 2.0 ecosystem |
| Achievement metadata richness | Moderate | Extended, supports CLR (Comprehensive Learner Record) alignment |
| Platform adoption (2026) | Widespread | Growing rapidly |
| Best for events | General attendance, workshops, CPD hours | Professional certifications, regulated industries, long-term credential portability |
| Supported by IssueBadge.com | Yes | Yes |
Why the "Open" in open badges matters for event organizers
The word "open" is not marketing language. It has real implications for how your credentials behave in practice.
No vendor lock-in
Because Open Badges follow a public specification, credentials you issue today remain valid and displayable even if you switch badge platforms, rebrand, or the issuing platform shuts down — assuming hosted assertions use a stable URL, or are exported in signed format. Your attendees keep their credentials regardless of what happens to the platform.
Interoperability across platforms
An Open Badge issued by your event can be stored in any compliant badge backpack, Badgr, Credly, Mozilla Backpack's successor services, and LinkedIn's certification section. Recipients are not forced into a walled garden.
Employer trust through transparency
Because the badge metadata is publicly inspectable, employers, universities, and licensing bodies can verify the badge without calling your organization or trusting a third-party verification company. The data speaks for itself.
What types of badges can you issue at an event?
A common misconception is that badges are only for completing a course or passing an exam. At events, the opportunities are far richer.
Attendance and participation badges
The most common type. Issued to every registered attendee who checked in, these badges confirm participation and list the event name, date, and location. Even a simple attendance badge increases the perceived value of attending your event.
Session and track completion badges
Multi-track conferences can issue session-specific badges. Attendees who complete three sessions in the "Data Science" track earn a "Data Science Track" badge. This granularity gives recipients a portfolio of competencies rather than a single monolithic certificate.
Workshop and hands-on training badges
Pre-conference workshops that require active participation — coding exercises, case study presentations, lab work — justify richer criteria and carry more professional weight. Include evidence requirements like submission links or QR-scanned check-ins so third-party verifiers can see what the badge actually represents.
Speaker and presenter recognition badges
Acknowledge speakers with a credential they can add to their professional profiles. A "Keynote Speaker, TechSummit 2026" badge on LinkedIn is a compelling professional signal that benefits both the recipient and your brand visibility.
Volunteer and staff service badges
Recognize event volunteers and organizing committee members. For early-career professionals, a verifiable volunteer badge from a respected industry event can make a real difference on a resume.
CPD and continuing education badges
If your event qualifies for Continuing Professional Development (CPD) or Continuing Education (CE) hours, badge assertions can carry the number of credit hours, the accrediting body, and the qualifying activity, replacing paper certificates with a shareable, verifiable digital record.
How open badges work technically: Inside a badge file
When you issue an Open Badge 2.0 credential, the badge image file contains a special metadata property, either baked directly into the PNG (using iTXt chunks) or referenced via a URL for SVG files. That metadata is a Json-ld object structured like this (simplified):
{
"@context": "https://w3id.org/openbadges/v2",
"type": "Assertion",
"id": "https://issuebadge.com/assertions/abc123",
"recipient": {
"type": "email",
"hashed": true,
"salt": "deadsea",
"identity": "sha256$c7ef..."
},
"badge": "https://issuebadge.com/badges/techsummit-attendance",
"issuedOn": "2026-03-16T09:00:00Z",
"verification": {
"type": "hosted"
},
"evidence": {
"id": "https://techsummit.example.com/2026/attendees",
"narrative": "Attended all plenary sessions of TechSummit 2026."
}
}
The recipient's email is hashed (SHA-256) so it is not stored in plain text, protecting privacy while still allowing verification. The badge field links to the BadgeClass object, which in turn links to the Issuer Profile, creating the chain of trust shown in the diagram above.
The business case for open badges at events
Beyond the technical merit, there is a compelling business case for event organizers to adopt Open Badges.
Increased perceived event value
When attendees know they'll receive a shareable, verifiable credential — not just a paper certificate or a name tag — the event feels more worth their time. That perception can support higher ticket prices or justify membership-tier differentiation.
Organic social amplification
Every time an attendee shares their badge on LinkedIn, they create a branded post that names your event and links back to your site. For a 500-person conference with a 30% share rate, that's 150 organic LinkedIn posts promoting your event — with no ad spend attached.
Improved attendee retention
Attendees who get tangible career value from your event are more likely to come back. Tracking badge issuance and sharing rates also gives you behavioral data on which sessions and tracks your audience actually cared about.
Sponsor and partner differentiation
Offer sponsors the option to co-brand a workshop badge. A "Sponsored by Acme Corp" badge credential outperforms a logo on a banner as a sponsorship asset, because it creates a lasting digital connection between the sponsor and the attendee's professional record — one that doesn't disappear when the event ends.
Compliance and audit trails
For events in regulated industries, healthcare CME, legal CLE, financial services CPD, Open Badges provide a timestamped, tamper-evident audit trail of credential issuance that satisfies accreditor requirements and supports regulatory compliance reporting.
How to issue open badges at your event: a step-by-step overview
The practical workflow for issuing Open Badges is straightforward with the right platform.
Step 1: Define your badge program
Before designing anything, decide which badge types you will issue, what criteria each badge requires, and whether any carry CPD/CE hours. Document the criteria in plain language — this text appears inside the badge metadata and should be specific enough that a third-party verifier can understand what it took to earn the badge.
Step 2: Design your badge images
Badge images should be square (recommended 400×400px or 600×600px) and visually communicate the achievement type. Use your event's branding, colors, logo, and typography, and differentiate badge levels with color or iconography. IssueBadge.com provides a built-in badge designer with event-ready templates.
Step 3: Configure the badgeClass and issuer profile
Set up your organization as the issuer, then create a BadgeClass for each badge type. Enter the name, description, criteria text or URL, and optionally map the badge to skills frameworks like ESCO, O*NET, or your industry's competency model.
Step 4: Collect recipient data
Connect your event registration system (Eventbrite, Cvent, Hopin, or a CSV export) to your badge platform. Each recipient needs at minimum a name and email address. For session-level badges, you will need session attendance data from your check-in system.
Step 5: Issue and notify
Trigger batch issuance, either immediately after check-in or after the event closes. IssueBadge.com sends each recipient a branded email with their badge, a shareable link, and instructions for adding it to LinkedIn, their resume, or a badge backpack. The whole process takes minutes, not hours.
Step 6: Monitor engagement
Track badge claim rates, sharing activity, and verification events through your platform's analytics dashboard. These metrics inform future event decisions and can be shared with sponsors as proof of engagement value.
Common mistakes event organizers make with open badges
Issuing badges with vague criteria
A badge that says "attended TechSummit 2026" with no further context has limited professional value. Include the event dates, total programming hours, and topics covered. The more specific the criteria, the more credible and useful the badge is to whoever receives it.
Using non-compliant image formats
Only PNG and SVG files support metadata baking in the Open Badges standard. JPEG files cannot carry embedded badge metadata. If you use JPEGs for your badge images, your badges will not be verifiable.
Relying on hosted assertions without a stable URL strategy
If you issue hosted Open Badges 2.0 assertions from a temporary domain or a domain that will expire after the event, all previously issued badges will break when verifiers try to fetch the assertion URL. Use a permanent, organizational domain as your base issuer URL, or use signed assertions that do not depend on a live server.
Sending badges too late
The highest LinkedIn sharing rates happen in the 48 hours after an event ends. Delaying badge issuance by weeks means missing that window almost entirely — and the organic reach that goes with it.
Skipping the attendee education step
Many attendees, especially those new to digital credentials, don't know what to do with a badge email. A short instruction helps: "Here's your badge — here's how to add it to LinkedIn in 60 seconds." IssueBadge.com includes customizable recipient guidance in every delivery email, so you don't have to write it from scratch.
