Rumor: Second-generation Samsung Galaxy A line-up will "probably" include fingerprint scanners
We could be getting closer to the release of some of the second-gen Galaxy A models. Just last week, we told you that the second-generation Samsung Galaxy A3 and Samsung Galaxy A5 had both visited the FCC, certifying the devices for use in the U.S. Both models come with support for NFC, which along with the fingerprint scanner, could indicate that mobile payment service Samsung Pay will be made available for the Galaxy A line. Right now, only Samsung's high-end Galaxy handsets are equipped with support for Samsung Pay.
Speaking of Samsung Pay, the service now supports eight new credit card issuers including Chase Visa cards, and Sun Trust Mastercards. The fingerprint scanner is used with Samsung Pay to verify the identity of the person making a payment.
