title: How to find out the NFC stack(chip) "NXP vs Broadcom" on Android devices
body: <p>Is there a way to figure out the NFC stack (or chipset) on the Android device? I am creating an app with a custom implementation for NfcV class (ISO15693 tags). Turns out on older devices like Nexus S, Galaxy S2, Nexus 7 the NFC chipset is from NXP and the only ISO15693 tags that are supported are the NXP ICODE tags. I have a custom implementation that relies on the transceive function. It works beautifully with TI and ST Micro tags. But the problem is, on devices like Nexus 10, Nexus 4 and SGS4 Google started using Broadcom NFC transceiver and their NFC stack which has native support for ISO15693 tags. Is it possible to identify the NFC chipset programmatically? If so how?</p>
