In the UK most banking apps on your phone, have a feature where you can lodge a cheque up to £500, by taking a pic of the cheque front and back with the banking app on your phone. The cheque is cleared and in your account in 24 hours, and the physical cheque never goes to the bank. You are told by the app to write LODGED on the back of the cheque and keep it just in case.
Also I notice if I pay my Irish Vodafone Bill, or Bord Gais, or ESB bill from my UK bank account, before 2pm, its credited to the Vodafone, Bord Gais or ESB bill account on the same day, whereas if I try to pay any of these bills from my Irish AIB account, it takes 2 days at least. Just a good example how to Irish banks once again, are holding our cleared funds for their own use, for as long as they can, before they let us have the benefit of our own money.
