I have 2 current accounts and 2 private credit cards. I use the credit cards for most of my spends and clear them 100% each month.
So my AIB account does recognise and categorise my AIB credit card spends per retailer category but it's far from great to be honest......
Not wonderful IMO.
If folk rely on their banks to provide detail on their spends then as I said.........
At the very least you would wonder why your shopping bill was too high and/or your petrol bill too low.
Zero barrier to entry also.
