OEM/ODM PCBA Processing for Location Card

BLE Location & iBeacon Smart Cards integrate ultra-low-power Bluetooth Low Energy (BLE) microcontrollers, RF antennas, and slim lithium batteries into standard ISO credit-card-thickness (<2.0 mm) profiles using prosmartcard (Union Smart)'s proprietary cold lamination technology. These active smart cards continuously broadcast cryptographic identity signals to Bluetooth gateways, smartphones, and access control readers for real-time indoor positioning, personnel safety management, and asset tracking.

How BLE iBeacon & Active Positioning Cards Work

• Configurable Periodic Broadcasting: The card periodically broadcasts data packets (default 500 ms interval, adjustable from 100 ms to 10 s) containing a unique MAC address, UUID, Major/Minor IDs, and battery telemetry.
• Signal Strength (RSSI) Triangulation: Deployed Bluetooth gateways, smart anchors, or mobile applications receive broadcast packets and measure Received Signal Strength Indication (RSSI) to calculate exact room-level or sub-meter positioning.
• Proximity-Triggered Automation: Mobile apps or cloud management platforms can trigger automated attendance logging, zone access permissions, welcome greetings, or SOS emergency alerts based on card proximity.

Core Engineering Capabilities & Hardware Options

• Proprietary Cold Lamination: Low-temperature, low-pressure sealing preserves ultra-thin rechargeable lithium batteries, Bluetooth ICs, and crystal oscillators without thermal stress, achieving credit-card thickness (<2.0 mm).
• Rechargeable & Non-Rechargeable Options: Supports magnetic contact charging, wireless Qi charging coils, or long-life primary batteries providing 12 to 36 months of continuous operation.
• Dual-Frequency NFC/RFID Integration: Combines active BLE transmission with passive NFC (NTAG/MIFARE) or UHF RFID chips in a single card, allowing simultaneous door access control and real-time indoor positioning.
• Custom Sensors & Peripherals: Supports integrated SOS distress buttons, motion accelerometers (sleep-on-rest power saving), vibration buzzers, and multi-color LED status indicators.
• Zero Mold Tooling Costs: Advanced cold lamination requires no expensive steel injection molds, enabling fast prototyping and flexible production batches.

Primary B2B Industry Applications

1. Personnel Positioning & Mustering: Real-time worker tracking, attendance verification, and emergency evacuation headcounts in factories, construction sites, and oil refineries.

2. Healthcare Staff & Patient Safety: Hospital doctor/nurse badge identification, infant abduction prevention, and panic SOS calling for elderly care facilities.

3. Smart Office & Enterprise Access: Dual-interface corporate employee ID cards combining physical door tap-in with hands-free indoor attendance and meeting room check-in.

4. High-Value Asset & Cargo Tracking: Slim beacon cards placed inside shipping containers, luggage, or warehouse pallet cages for yard management and logistics visibility.
