The electric two-wheeler market — e-bikes, e-scooters, e-motorcycles — is one of the world's largest EV segments. Yet access remains mechanical: a physical key. Keys get lost, forgotten, or duplicated. Meanwhile, NFC is already in the pocket of 70%+ of smartphone users. YQM ELECTRONICS provides an ultra-low-cost NFC unlock module that replaces physical keys with a tap of the user's phone or wearable.
1. Application Scenario
Traditional e-bike locks: one key, one vehicle. Keys get lost, no family sharing, no usage logging. With NFC in most smartphones and wearables, the hardware for a better solution is already in every rider's hands.
2. Solution Features
- Easy Vehicle Integration: Minimal electrical modification — connects via smart alarm interface or main control board.
- Ultra-Low Cost: BOM optimized for price-sensitive markets — smart-key functionality at a fraction of Bluetooth/4G module cost.
- Extended Read Range: Optimized antenna for reliable NFC detection at practical distances.
- Effortless UX: Tap to unlock, tap to start, tap to lock. No more forgotten keys.
3. Solution Architecture
Two integration options: (1) Smart alarm interface — simplest path, minimal wiring changes; (2) Main control board interface — supports usage logging, remote key authorization, telematics integration. Core functions: NFC unlock, start, park, lock (one-tap-on, one-tap-off). Family key sharing: grant temporary keys to family members via APP with dynamic access management.
4. Core Technical Principles
The phone/watch operates in NFC-PICC (card emulation) mode, presenting a virtual card to the vehicle's reader. Card data is dynamically assignable and rewritable. Authentication uses UID whitelist, encrypted sector data, or dynamic rolling codes depending on security level required. Supports both fixed-authorization (family vehicles) and dynamic-authorization (shared fleet) models.
5. Cooperation Models
Two tiers: (1) NFC kit (driver library + NFC chip + reader antenna + NFC tag); (2) NFC module (integrated module with antenna + tag). Contact YQM for integration details and samples.
Conclusion: NFC Keyless Start — The Smarter Way to Access Two-Wheelers
NFC keyless start replaces physical keys with the smartphone already in every rider's pocket — reducing mechanical key management costs for fleet operators and delivering a premium tap-to-ride experience for consumers. YQM ELECTRONICS provides ultra-low-cost NFC unlock modules purpose-built for the electric two-wheeler market, with flexible integration paths via smart alarm or main control board interfaces.
