Isn't it causing you an uncomfortable feeling, that one company gets all the data about every single thing you buy?
And via this also everywhere you go and when you go there?
So you are a 100% "see through" person to Apple, Google and/or Visa?
That's just your bank. If a global payment processor like Visa would leak data, there probably would be ripples going through most financial system (i.e. whole countries abandoning it, etc).
The name+address+DOB of many people are public. So anybody who gets a glimpse at someones "card" (I guess you mean credit card?) would be able to take over their gmail? That would surprise me.
Do you have a link that confirms this?
I think what I've realised (at least personally), is that we only have a short time to live on this planet, and if life can be made more convenient by offering up my data, allowing me to spend my time doing stuff I actually care about, then I'll do it.
Personally, I'll stick to using the special transport card or cash on public transportation as long as I can. I hate the idea of all my movements being sold to advertisers (or, actually, anyone paying some moneys).
I feel much more comfortable spending money, knowing that;
1. It's the banks money, I can contest any changes on my statement before any money leaves my account. (consider paying for a bathroom renovation and the builder runs off with money or goes bust. The bank takes the hit, not me.)
2. That mass-data helps protect me, such as, abnormal usage can be queried for protentional fraud automatically.
