...used the mobile wallet to make a contactless payment, according to Visa and its trial partners, and 70 per cent of the participating retailers have been paid by mobile.
Just over half of the triallists (52 per cent) are regular users of the mobile payments service, making one or more contactless payments per week, while 48 per cent are occasional users, making an m-payment every 15 days or longer.
The majority of purchases - 60 per cent - made using the contactless handsets fall into the sub-€20 bracket, about a third (30 per cent) of which cost less than €6.
Supermarkets have been the most popular retailers for Sitges trialists to whip out their mobile wallet, with 52 per cent of the purchases being made in 'supermercados'. After supermarkets, restaurants were next most popular places, accounting for 14 per cent of all the transactions, followed by clothes shops (six per cent) and pharmacies (four per cent).
According to feedback from trialists, 70 per cent said they were highly satisfied with the mobile wallet payment experience. Asked whether they would use the wallet in future, over half (66 per cent) said they would definitely do so, a quarter (25 per cent) said they probably would, and eight per cent said perhaps. None of the trialists said they would "probably not" or "definitely not" use it in future.

Better and faster mobile networks - with 3G and even 4G network rollouts - are also putting wind in the sails of mobile payments.
However Harris said that big hurdles still remain, including...
