I embraced internet banking of about a five years ago. I transfer money between my accounts. I pay all bills. I pay R money that I owe. I just paid a friend for tickets for a show. Against my better judgement, I even used net banking in a public library when we away recently. It was pretty well unavoidable. Tenants can can waylay the best laid plans. Internet banking is marvellous and so easy.
Do I feel comfortable doing it? Not really. I am sure one day that I am going to put an extra zero into a figure or pay the wrong person or use the wrong account. I obsessively check and recheck figures, confirmation details and final figures. I write figures down or cut and paste them on records.
I am not at all worried about fraud or security issues, but I do worry about my own fallibility.
