Convenience is exactly the issue. Technology tends to make our lives easier. I don't even have to take my wallet out now, just use my phone. It's just so much easier. The transaction fee thing is annoying, but most of the time it's so small I just pay it anyway, instead of going through the above-mentioned steps to pay with EFTPOS. I'd also add "chose the wrong account and it was declined" to those steps. I use EFTPOS so infrequently now I often forget which account I keep all my money in.
