This is an adapter for converting a B-CAS card to a mini B-CAS card. If your newly purchased TV or recorder only supports mini B-CAS, this allows you to reuse your old card, potentially saving you the trouble of transferring your card contract. Some B-CAS insertion slots may be a bit tight. Please insert the card carefully, widening the slot if necessary. Although this is a new product, it is an imported item, so there may be some minor scratches, dirt, or folds in the cord that do not affect its functionality. Please pay attention to the shape of the mini B-CAS insertion slot. There are types that insert from the notch side and those that insert from the opposite side, so please check your device. I have confirmed that it works with my Toshiba TV at home, but please understand that it may not work depending on the compatibility with your device. It seems that even Toshiba TVs are not guaranteed to work. Instant purchase is OK. Management No. 043
