Hi Eliseo, > so Nexus S, Galaxy Nexus and Galaxy S III have a fixed UID?
These phones have an embedded secure element that has a fixed UID. > it is due to the NFC NXP controller or to the secure element? Secure Element. The NFC controller uses random UIDs for all other cases. > Which secure element they have? The embedded secure element on the Nexus S/Galaxy Nexus is a SmartMX from NXP. > In a previous post, Nikolay say that "You can't fix the UID, at least > not with any of the standard NXP controllers.". Is it correct? For NXP's PN544 that's correct. For peer-to-peer mode and software card emulation, that NFC controller will use a random UID/NFCID1. Only in secure element based card emulation mode, the UID provided by the secure element is used. > the fixed UID depends of the SE present on > the phone? In case of random UID, what kind of SE is present? It not only depends on the SE being present. For the SE's UID to be used, the phone must also be in card emulation mode using that secure element. > Which android phones can do software card emulation? is it made by the > OS or by one custom application? The CyanogenMod 9.1 firmware contains patches to enable card emulation on phone's with NXP's NFC chipset (PN544). So any phone that you can put CyanogenMod on and that contains a PN544 should work. The standard Android OS on the phones is currently not capable of software card emulation.
