How much does it cost a business to manage say 10K company cards, maybe even globally? Sounds like a huge hassle, compared to "Send us a photo of your lunch receipt each day then at the end of the month we reimburse you".
That's something else, isn't it? Or how do you pay with those at a typical POS terminal at a random lunch place?
Any ideas why the companies in the article doesn't just do that to fight the fraud then?
But, to the degree that fraud becomes a real issue, it may be the simplest thing to do.
