In the shared power bank rental market — a multi-billion-dollar industry spanning shopping malls, restaurants, transit hubs, and entertainment venues — the user experience bottleneck is clear: QR-code scanning. Users must unlock their phone, open an app, scan a QR code, and navigate payment confirmations in often poor lighting conditions. YQM ELECTRONICS introduces an NFC tap-to-pay power bank module that eliminates every friction point: the user simply taps their phone against the power bank to instantly initiate rental — and taps again to return and settle — without opening any app.
1. Application Scenario: Replacing QR Codes with NFC Touch
Traditional shared power bank systems rely on QR-code scanning for both rental and return. This introduces multiple friction points: users struggling with phone cameras in dim venues, QR codes wearing off, cellular dead zones preventing app load, and 15-30 second delays. NFC tap-to-pay solves every dimension: the transaction begins the moment the phone contacts the power bank, using the NFC Secure Element for bank-grade security without screen interaction. The return flow is equally frictionless — tap the power bank back into the station to automatically complete settlement and refund the deposit.
2. Solution Features
- Tap-to-Rent, Tap-to-Return: NFC initiates rental with a single tap. Return triggers automatic settlement and deposit refund — no app screens to navigate.
- App-Free User Flow: Uses the phone's built-in wallet infrastructure — no separate app download required. As seamless as tapping a transit card.
- Offline-Capable Transactions: NFC payment tokens are pre-authorized and cached on-device, allowing transactions in signal-poor environments where QR systems fail completely.
3. Solution Architecture
The system integrates an NFC controller, secure element, and antenna coil into the power bank's compact enclosure. On the station side, an NFC reader module handles return detection and settlement. The architecture supports both standalone NFC payment (card-emulation mode) and APP-mediated flows for operators preferring proprietary wallet integration.
4. Core Technical Principles
NFC tap-to-pay leverages ISO/IEC 14443 and EMVCo contactless payment specifications. The power bank module operates in card-emulation mode (PICC), presenting a virtual payment token to the user's phone (PCD). Each tap generates a unique transaction cryptogram via the NFC Secure Element, preventing replay attacks. Temporary payment credentials are issued by the operator's backend and refreshed per session — even if a token is intercepted, it cannot be reused.
5. Services & Support
