Has anyone tried using an RBS Digital Banking token card reader device in Switzerland?

I have requested one of these to add my new ZKB account as a payee to their digital banking service but I'm doubtful whether the reader will be able to receive a token/response from the UK.

The RBS website vouches that it works abroad so just wondering if anyone out there can vouch for the service?

I think you misunderstand how they work. There's no comms involved, just a hard-coded input/output code conversion.

And yes, I have successfully used the RBS one for quite a few years.

Thank you very much Ace1, that's great to know and quite a relief too
