1) I've already stated that First Choice and HSBC are discontinuing this.
2) Your official PDF from Natwest does not state that they are stopping issuing Maestro cards at all. It states that it can change your card type when it sees fit.
3) You trust Wikipedia? I could go and change that and it would be left like that for a number of hours, day, weeks or months until someone can verify that my claim is inaccurate.
4) Money Saving Expert has been known to be wrong on various occasions.
Just because a couple of banks have updated their terms of service to allow them to issue a card as they see fit does not mean that the dreaded Maestro card is being discontinued. Whilst I accept that RBS may be changing their cards in the future, they have sent you no official confirmation other than VISA announcing in September last year that they've signed a deal.
Additionally I didn't say that you were wrong, I said that they haven't discontinued it. Which is correct, they may be migrating some customers over, but that card is not being discontinued.
Furthermore, the Maestro card is much better than it's comparison the Visa Electron card for many reasons. Not only because of acceptance of the card, but also because most Electron cards don't have their details (such as PAN, BIN numbers) embossed onto the cards. This means that when a retail outlet has to revert to an older method of accepting cards (such as when systems crash) they are unable to accept Electron owing to fraud reasons. This is where Maestro wins as on most cards they are embossed and most of them tend to have Issue numbers.
Besides, the fact remains that they now have the facility to use both sets of cards which is the best option for the customer. Just ensure that you avoid Solo or AMEX cards as they're just awful.
