I bet people said the same thing about credit cards — “how do I know there won’t be an error that causes my credit card bill to be wrong at the end of the month? I’ll stick with cash thank you very much”
I mean, until the technology had been proven, I think that's a valid question to ask.
Plus, when credit cards were introduced, you were still given the opportunity to agree upon the total on which you'd be charged, before you were charged. That's all I'm asking for with this.
