自動車製造の課題
Automotive manufacturing is the Olympics of logistics. With thousands of parts converging on the assembly line in 'Just-in-Sequence' (JIS) order, a single missing bolt or mislabeled trim piece can halt the entire line, costing thousands of dollars per minute.
Counterfeit parts are also a growing threat, compromising safety and brand reputation. Without a secure, digital chain of custody, it is difficult to guarantee that every component in the vehicle is authentic and meets OEM specifications.
Recall management is another nightmare. When a defect is found, manufacturers often have to recall far more vehicles than necessary because they lack granular data on exactly which batch of parts went into which specific VIN.
Key Pain Points
JIT複雑性
ジャストインタイム製造では、1つの欠品部品がライン全体を停止させ、1時間あたり数百万円のコストが発生します。
リコール対応
欠陥部品が数千台の車両に使用された場合、その全てを追跡して召回する必要があります。
偽造部品
危険な偽造部品がサプライチェーンに侵入し、安全性とブランド評判を脅かします。
車両誕生から廃車まで追跡
Nextwaves embeds high-memory, high-temperature RFID tags into critical components—from tires and airbags to engine blocks and electronic control units (ECUs). These tags survive the harsh manufacturing process, including paint ovens and welding.
As a chassis moves down the line, readers verify that the correct parts are being installed in real-time. 'Smart Racks' automatically signal for replenishment when parts run low, automating the Kanban process.
The result is a 'Digital Birth Certificate' for every car. We know exactly which airbag (Serial #123) went into which VIN (Vehicle #ABC), creating a permanent digital link for the vehicle's entire lifecycle.

詳細解説：AIAG標準
Automotive applications often require more data than a standard license plate. We use High-Memory tags (up to 4KB user memory) to store maintenance history, build data, and safety specs directly on the part itself. This allows the part to be 'smart' even when disconnected from the network.
For security, we utilize DNA-based physical unclonable functions (PUF) or crypto-chips that authenticate the tag. Even if a counterfeiter copies the data, they cannot copy the physical fingerprint of the chip.

未来：V2X通信
RFID is the first step toward V2X (Vehicle-to-Everything). In the future, the car's internal RFID readers will constantly audit its own health, communicating with smart city infrastructure to book its own service appointments or pay for tolls and parking automatically.
