No real code required: click through the main workflows directly in your browser.
No invented usage figures—this MVP demonstrates verifiable workflows and states instead of advertising vanity metrics.WHAT 4CRYPT DOES
The link stays. Everything else can change.
Dynamic
Change destinations any time without touching the QR code or NFC tag.
Measurable
Analyze scans, devices, countries and time ranges with privacy in mind.
Find mode
Return found items securely without exposing private information.
Controlled
Manage tenants, invitations, limits and access from one place.
SECURITY THAT STAYS OUT OF THE WAY.
Tokens are generated cryptographically. Every customer sees only their own workspace. Scan analytics work without tracking cookies and IP addresses are processed only as a daily rotating hash.
