Hi Joanna, thanks very much. I have had a conversation with someone who is involved in the loyalty card section of one of the large UK supermarkets who informed me of the type of information they find valuable which was interesting. This is my first contribution to OpenIDEO so I'm familiarising myself with the process, I'll happily speak to a retailer if the feedback stage is encouraging to develop the solution.
Thanks Ana for your note. I think the financial reward is crucial to inspire people into action to be healthy and I believe the media channel is the social element that will maintain a long term change.
