KOSMORelay Cash

Your subscribers already trust you with their connectivity — fintech startups are the ones capturing their payments instead. KOSMORelay Cash puts a secure digital wallet directly into the SIM you already control, so transactions keep working even offline, and the relationship stays yours.

Key features

Payments that work anywhere.

SIM wallet technology

Secure digital wallet embedded directly into SIM/eSIM, supporting contactless payments, crypto, and banking rails with 256-bit encryption.

Works offline

Compatible with virtually any mobile device, including legacy hardware — peer-to-peer NFC transfers with zero connectivity.

Bank-grade security

Hardware-level encryption and multi-factor biometric authentication — PCI-DSS, GDPR, and AML/KYC compliant.

Multiple revenue streams

2.5% transaction fees, $5/month premium subscriptions, and 1.8% issuing fees for financial institution partners.

The mechanism

How a transaction actually completes.

The same four steps whether the subscriber has full signal or none at all — that's the point of building the wallet into the SIM.

01

SIM secure element

The wallet lives on the SIM/eSIM itself, not in an app that needs a live connection.

02

Transaction initiated

NFC tap, QR scan, or an online payment — the subscriber's device decides which is available.

03

Local verification

Biometric check plus hardware encryption runs on-device — no network round-trip required to authorize.

04

Settlement

Instant if online; queued and synced automatically the moment connectivity returns.

The product ecosystem

Three components, one wallet.

KOSMORelay Cash Wallet

The digital cash system itself — multi-currency support, offline transactions secured by distributed ledger technology.

Embedded finance integration

Standardized REST APIs and SDKs that connect to your existing systems — NFC, QR, and legacy banking rails supported out of the box.

White-label SuperApp

Biometric onboarding on a modular, low-code platform, so you can plug in third-party services without a rebuild.

Customer journey

Live in under 3 minutes.

The entire path from getting the SIM to completing a transaction is designed to remove friction, not add a form.

1

Acquisition

Customer obtains a KOSMORelay-enabled SIM/eSIM through retail partners, online platforms, or digital marketplaces.

2

Activation

Seamless digital install via the SuperApp or embedded SIM toolkit — the subscriber keeps their existing number and carrier relationship.

3

Onboarding

KYC with 256-bit encryption for data stored in the SIM's secure element — multi-factor identity verification in under 3 minutes.

4

Utilization

Immediate cross-platform use via NFC, QR, and offline payments — integrated with financial service providers worldwide.

Market opportunity

A $15T global payment ecosystem — still mostly untapped by SIM.

Cash still dominates globally, but digital payment methods are growing fast. SIM-based solutions sit at just $0.2T today — the smallest slice of a massive market, and exactly where KOSMORelay Cash is built to grow.
