I had a client the other week, who had no cash after his massage, and offered Pingit (supposedly he did not have PayPal (which I have not had problems with yet)). He sent the funds, and I received an immediate text saying the amount had been sent to me, and that I have 7 days to download the app and claim the funds..... The client then left.... I went ahead to download the app, but it took a while. 12 minutes later I received a text telling me "something went wrong, please contact the payee.' It appears that as long as I did not have the app yet registered to my mobile number, and or the payment is pending - there is a very easy option to simply 'cancel' a pending payment!!!! Pingit have as of yet been unhelpful ,the Barclays Pingit team simply claimed that any pending bank transaction can be reversed easily, supposedly I should have know that?! ---- I would not recommend Pingit! Not sure if the payment would have been irreversable under different circumstance (like me being a registered user already), but if you do decide to use it, I'd recommend finding out beforehand.
