"Coinomi" on the play/apple store can scan and redeem all forks as well for cas coins.
Edit why buy a one-time card to sweep a coin?
I agree that buying a card specifically for this purpose would be silly but there are many that use them regularly or have them around already - in that case it makes just as much sense as the coinomi app
I will say this though - once you import the key, DO NOT use the SWFT exchange services within the app to convert the forks. I tried this and when I sent BCH to be converted to BTC, it took the BCH ABC and the BSV as well and only gave me the BTC for the BCH.
I will admit that Ballet did work with SWFT and I have received the BCH ABC back but am still waiting for the BSV.
They said they are working to ensure this does not happen in the future. But not sure if I will risk another coin to find out.
