Man... the FUD in this comment thread is ridiculous.
First, no image is transmitted to apple for OCR. You don't even 'take a picture'. You have a live camera shot and the app lifts the data off the card via OCR while the picture is still moving, and it's not 100%. What it does get is accurate, but it misses half the data more than half the time.
Second, doesn't anyone here at all realize that by using MCX, you will be shifting fraud liability from CC companies to the buyer? Yes, it's true. Those CC fees cover a lot of fraud liability, but debit swipes don't have near the same legal protections.
Third, and this one is really goddamned important -- ACH transactions (unlike CC tx) are subject to overdraft fees. Yes, that's right. The return of those absurd $32+ fees and transaction structuring that banks use to rape people living paycheck to paycheck. Most banks no longer have limits, and will charge you upwards of 7 fees a day! BoA did this crap with me for years when I was a struggling young adult. Structuring my transactions to maximize fees, then raking me over the coals, time and again. MCX would set back overdraft legislation by a decade.
Lastly, MCX freely admits to collecting as much data (including health data) about you as possible, and transmitting it to the retailer. Does freaking walmart really need to know if you've gained weight this month so they can push weight loss pills on you?
Apple pulls a lot of marketing bullshit, but at least they aren't farming my sleep habits out to retailers. The data grabs are sick, and need to stop. It's why I switched from and android that I loved to an iPhone I like. I will never install CurrentC, I will never go back to Google. Time to wake up, and make your choice between evil corporations.
