audioguy58 It looks as thought the InControl product from Master Card has been around over ten years, and hasn’t exactly set the world on fire.
Are you in the US? I have Aussie friends living in the US and they always say the financial system is 30 years behind everyone else.
I would say it's pretty much ubiquitous except for America. Certainly in Australia it's just a normal feature of your banking. You can set limits on whatever you want. I didn't realise it wasn't a "thing" elsewhere... Hardly anyone uses cash here, everything is done with your card or your phone. We don't even use pin numbers or signatures for anything under $200, just tap and go.
Once I was on holiday in Melbourne and the bank actually rang me up and asked if I was shopping on Chapel St, because I think I set off some alarms somewhere. Only drug dealers and dodgy tradies use cash these days!
