Frequently Asked Questions
Straightforward answers about QANTRA Personal & Teams.
Do people need an app to view my profile?
No. Anyone who taps your wristband or scans your QR code sees your profile directly in their phone's native web browser (Safari, Chrome, etc.). No app installation or account creation is required.
How does contact saving work?
When someone views your profile, they can tap "Save Contact". Their phone prompts them to add your details (name, phone, email, company, and links) directly into their address book via standard contact file (.vcf).
What phones are compatible with NFC?
Virtually all modern smartphones (iPhone XS and newer, and most Android devices produced in the last 6+ years) support background NFC reading. For devices without NFC, a QR code provides an instant fallback.
Can I update my details after receiving the wristband?
Yes. Your wristband links to your live web profile. You can edit your contact details, photo, links, and bio anytime, and the next tap will display your updated information.
How can I equip my team or company?
