I assume it's just that the AP limit of £1000 is an order of magnitude higher than the limit for a physical card. (Maybe the Transit limit should be lower?) I would also assume that this is why the article references Samsung Pay but not Google Wallet - the former seems to have a Transit-like option but not the latter?
