I set it up the other day mate. And i have now put it on my tickets for "smartphone users", yet to recieve a payment but only put a few tickets out.
My mate set it up and he is with barclays and sent me a payment, im really impressed with it, no charges and as my number was in his phone book he just had to search for it and click then the amount and send. Simple.
I also like the fact i reveiced a text from him that also had a personal message in it where the cutomers could put address etc.
If all my customers used it, id be over the moon.
