Please purchase without needing confirmation. ^^ I do not offer discounts, so please refrain from comments asking for a price reduction. m(_ _)m This adapter is used to allow a standard B-CAS card to be used in devices that support mini B-CAS cards. Even if your new TV or recorder only supports mini B-CAS cards, you can continue to use your old card. There are two types of conversion adapters: Type A and Type B. Please purchase the one that suits your needs. This listing is for Type B, which is inserted into the device with the notched corner facing inward (insertion side). Please check the images for details. Type A is listed separately, so please tap below. #ConversionAdapterATypeBType ・Purpose: Conversion from B-CAS card to mini B-CAS card ・Type: Type B (insert with the notched corner facing inward)
