Can EMID signal cards be used on metal surfaces?

[admin]

Model: BS6A, BS5C

Since non-contact signal cards rely on electromagnetic waves to transmit power and data, their effective reading distance can be shortened when used on metal surfaces. When the cards placed on less conductive metals such as iron, the effect is minimal, and the cards can be used normally. If the cards are placed on more conductive metals such as aluminum and copper, to eliminate the strong effects of those metals, they should be elevated from the metal surfaces by 5-10mm using card installation seats. Specially designed cards that are not affected by metal can also be used, which can be installed on or beneath metallic surfaces.

There is also available a kind of special signal card model that can be embedded directly inside metallic surfaces. These are generally used to keep track of equipment usage.
