Abstract
A card having a fingerprint sensor and a manufacturing method of the same are provided. The fingerprint sensor is disposed between a substrate and a protection layer. The protection layer has a first area and a second area thereon. The roughness of the second area is smaller than the roughness of the first area. The second area corresponds to the sensing area of the fingerprint sensor. When the user's finger is wet, the second area may effectively keep the water from remaining on it. Thus, the water does not affect the effect of fingerprint sensing.
