SaferSIMShop demo
Security flow demo

Secure via eSIM

Your SIM is your secure login.

Register once and approve every login in the protected STK PIN dialog. The PIN and the private applet key never reach the app, website or server.

Testkonto: keine echte Bestellung, Zahlung oder Lieferung. Nur Testdaten verwenden.
Test account: no real orders, payments or deliveries. Use test data only.

SaferSIM registration and sign-in

The demo password is no longer used here. Customer authentication uses the username, applet challenge and the PIN only inside the STK dialog.

Returning customer

Sign in with SaferSIM

Enter your username. Your eSIM receives the Shop challenge and asks for your SaferSIM PIN directly via STK.

This website never asks for your PIN. The PIN is checked locally by the applet simulation or real eSIM applet.

PIN stays inside the eSIM prompt Challenge expires after 3 minutes Lab can forward, but cannot approve

End-customer journey

  2. 02Connect SaferSIM

  3. 03Confirm securely

    Confirm pairing once, then approve registration and later logins with the local SaferSIM PIN.

What happens technically?

Shop challenge. Secure relay. Direct applet proof.

01

Shop

Creates and signs a random, short-lived challenge bound to the customer and applet.

02

Lab relay

Authenticates both sides and forwards exact signed bytes over the secure applet channel.

03

eSIM applet

Verifies the Shop key, checks the PIN locally and signs the exact result. Only that proof logs the customer in.
