No, it means that the old JL card site, that was operated by HSBC, is completely shutting down and will cease to exist and any remaining card will be operated by HSBC.
As far as I know the old site and any cards are now defunct. Possible any that have not been transferred, but whose end date has not yet been reached maynominally still be open.
I was accepted by the new operator and I am more than happy with the way it works. In particular I do not have any online bank accounts, but can pay my card off each month online with my debit card. I have been looking for a visa account that operates in a similar way, but without success.
