Kamen Rider's ten-year card reading method relies on the bar code in the lower left corner of the card. Bandai is really good at making toys. Their products are not only excellent in appearance design, but also have many functions and features. For example, the card reading function of Decade and W-belt is realized by sophisticated mechanical and electronic systems. These toys are designed and manufactured with the user's experience in mind, and provide realistic effects as much as possible.

For W-belt memory card reading, it seems to be triggered by inserting the memory and pressing the button during the insertion. This action will make the belt emit a specific sound effect, and the memory will be read by the mechanical device inside the belt. Bandai considered playability and interactivity when designing these toys, allowing players to participate in the story in a realistic way.

In short, Bandai's strength in toy manufacturing is reflected in their excellent design, high-quality material selection, accurate production technology and thoughtful user experience. These factors together make their products widely recognized and loved all over the world.
