Consumer Action published a guide on mobile payments using your smart phone.
"The idea behind mobile payments is simple: Instead of paying with cash,
check, credit or debit card, consumers can use their smartphone to pay
for purchases via a mobile app."
"To help consumers understand their mobile payment choices, Consumer
Action looked into how four of these payment systems work. Popular
mobile payment systems Apple Pay and PayPal Mobile recently gained two
new competitors: Android Pay and Samsung Pay."
