In modern campus life, student ID cards are no longer just access passes. They now combine identification, payment, and notifications in one smart card. The addition of vibration motors enables real-time interaction, especially in location tracking and payment scenarios.
1. Vibration Feedback for Location Tracking
Built-in GPS/Bluetooth tracking modules allow parents or school systems to monitor student locations. The motor gives instant vibration alerts:
- Short buzz: Location confirmed
- Continuous buzz: Student deviates from safe zones
This discreet feedback ensures awareness without disturbing others, enhancing safety.
2. Vibration Feedback for Payments
When paying at cafeterias, libraries, or stores, one strong buzz confirms "payment success." This reduces errors caused by noise or visual distractions, improving transaction efficiency.
LEADER’s Coin Vibration Motors (LCM0720 & LCM0820)
1. Thin Design
- Thickness: ~2.1mm (fits ultra-thin cards)
- LCM0720: Medium vibration for subtle feedback
- LCM0820: Stronger vibration for critical alerts
2. Cost-Effective
Mature manufacturing ensures stable performance at lower costs compared to brushless/linear motors. Ideal for student cards.
3. Long Lifespan
High-precision copper bearings and low-power design enable 100,000 vibrations per motor.
- 10 daily uses = 3,650 uses/year → Lasts 27 years (exceeds student lifecycles).
4. FPCB Design Advantage
Flexible printed circuit boards (FPCBs) adapt to tight card spaces, simplify assembly, and boost production efficiency.
