Not if the mobile operators don’t sort out their customer service issues, it won’t.
Here are a few positives about cash. It is worth the same, whether you are a new customer or old. It doesn’t cease to operate when the system goes down (although admittedly an empty ATM at midnight is a bit of a bore). Keep your wits about you, avoid fakes and you won’t be landed with a non-functioning fiver that is costing you money on a monthly contract while resolutely refusing to work. It rarely requires repeated calls to call centres.
Perhaps I should apologise for bringing the personal to the professional but the point is real – there’s a lot more to simplicity than point and pay. Mobile payments could end up like the proverbial duck – all very impressive above the surface but with a heck of a lot of furious paddling, not all of it productive, going on underneath.
