Question [Q] NFC reading of CC and passport blocked on recent Android?

Hi!

I have 2 devices : Galaxy S3 and Galaxy Note 2. Both could read CC and passport NFC chips with the apps I have (and would identify the NFC chip with a audio feedback when present). I note that since I've updated both of these devices recently, they can't read the NFC chips on several NFC enabled credit cards I've tested, as well as on my passport.

They can still read other NFC tags easily... and even write them. Just credit cards and passports don't work anymore.

Wondering if this is something that may have been recently introduced in Android?

The S3 is running Kit Kat (Cyanogen Mod 11.0). The Note 2 is running a stock Samsung 4.3 (latest) but rooted.

Anybody notice something similar?

Ideas?

Gilles.
