Access Control / Interactive field guide
Mobile Credentials vs. Key Cards for Business Access
Compare mobile entry and key cards for business doors, including Brivo, HID, UniFi Access, and Avigilon credentials, onboarding, fallbacks, and testing.
What you’ll leave with
Choose credential options and define enrollment, fallback, and departure workflows.
- Mobile apps and wallet credentials are different experiences.
- Test the actual readers and user devices.
- Provide a controlled fallback and prompt access revocation.
A credential is useful when the right person can use it reliably and an administrator can manage it throughout that person's relationship with the business. Mobile entry and physical cards can both meet that goal. The choice depends on your readers, platform, employees, visitors, and support process.
Treat this as a workflow decision rather than a contest between phones and plastic. Some organizations benefit from offering more than one supported method. The important work is defining which options are allowed, how they are issued, and how access is removed.

Choose a credential policy to evaluate
Explore a practical mix of mobile and physical credentials based on your workforce, visitors, and device policy. This plans the workflow; platform support still needs confirmation.

1. Identify the exact credential technology
A mobile app, a wallet credential, and a remote-unlock button are not the same experience. Likewise, cards that look alike may use different technologies. Name the exact reader, controller, credential, and management platform in the scope instead of assuming that a phone or badge will work because it carries a familiar brand.
Brivo, UniFi Access, and Avigilon offer multiple entry methods within their product ecosystems. HID Signo readers support several credential technologies, but the required credential service and controller configuration still need verification. Manufacturer documentation is a starting point; test the combination being proposed for your doors.
2. Compare the daily workflow
Assign a real owner to each workflow. Fast enrollment is less valuable if nobody knows who can approve a replacement on a weekend. Make sure temporary access has a clear end time and is reviewed rather than becoming a permanent exception.
| Situation | Mobile credential planning | Card or fob planning |
|---|---|---|
| New employee | Check device support, invitation delivery, activation, and training. | Prepare stock, enrollment, distribution, and any badge printing. |
| Credential unavailable | Define help for phone replacement, battery issues, or unsupported devices. | Define help for a lost, damaged, or forgotten card. |
| Visitor | Confirm whether an app or compatible phone is required. | Define issue, expiry, return, and accountability for temporary badges. |
| Employee departure | Revoke the user's credential and review any other access methods. | Revoke electronically and record any returned physical badge. |
3. Account for the people using the system
Ask whether employees can and want to use personal phones for entry, whether company devices are available, and whether any work areas restrict phone use. Include accessibility needs and the way people enter while carrying equipment, wearing gloves, or arriving in groups. A small pilot can reveal friction that a product specification cannot.
Provide a supported fallback for employees or visitors who cannot use the primary method. It should follow the same approval and expiry rules as ordinary access. Avoid solving inconvenience with a shared permanent credential that makes accountability harder.
4. Plan enrollment, changes, and revocation
Decide who approves access and who administers the platform. Build groups around required locations and schedules, then make exceptions visible. When a person changes roles, review both the new permissions and the old ones. Removing a physical badge from a desk is not a substitute for disabling its access.
Brivo documents centralized credential issuance and revocation. Avigilon's administration documentation lists several credential types that can be assigned to users. For any platform, confirm how changes reach the door equipment and what staff can do when communication is interrupted. Do not assume that an update is effective everywhere merely because an administrator saved it.
5. Test a representative group before rollout
- Use the actual phone models, operating systems, cards, readers, and access methods intended for production.
- Observe entry at busy times and ask users to complete enrollment without extra coaching.
- Test a replacement credential, a temporary visitor, a revoked user, and an expired access window.
- Verify the planned fallback and document which functions require network or internet connectivity.
- Confirm that administrators can explain an access event without granting themselves unnecessary permissions.
6. Include the ongoing work in the decision
Compare credential charges, platform subscriptions, replacement stock, printing, enrollment time, and support work over the same period. Ask which costs change with user count or credential type. Select the approach that fits the actual workforce and administration process, then document it in a short onboarding and departure checklist.
Common questions
Must everyone use a phone?
No. Define supported alternatives for people who cannot use the primary credential method.
Does collecting a card remove access?
No. Revoke it in the access system and review the person's other active credentials.
