Thanks for all the feedback.
I too felt uncomfortable about the iPhone plug-in device, but then I though I might just be "old fashioned".
To be honest 40% of trade is on-line bookings and the rest seem happy to pay cash (even large amounts) as we have a cash point 25m away. We are looking into the WorldPay terminal, but the monthly payments do make it less attractive.
I am surprised that it takes 14 days, as all the info put out be Izettle states 4 days!
Thanks as always for the feedback.
