finding which devices use which chips

 * http://en.wikipedia.org/wiki/List_of_NFC-enabled_mobile_devices
 * Would be a great resource, if it was populated
 * http://www.shop4nfc.com/nfc-compatibility-chart - List of different devices and the NFC chips they use
 * But they seem to have the wrong chip for some Sony devices
 * This seems to be a handy site for finding out what chips a particular product uses:

Vendors of Secure Elements
ST Microelectronics NXP Secure Inside Infineon

Vendors of NFC chipsets
Note, ** means that recent firmware versions are qualified (by MasterCard) for payments with HCE (Host-based Card Emulation) and SE (Secure Element)
 * NXP
 * PN544 C1, PN544 C2, PN544 C3**
 * PN65N (PN544 C2 + SmartMX secure element)
 * PN65O** (PN544 C3 + SmartMX secure element)
 * PN547 C1, PN547 C2**
 * PN548 C2
 * Broadcom
 * BCM20793M
 * BCM20793S (includes a secure element)
 * BCM20794
 * Secure Inside
 * MicroRead

News
Google supports Host Card Emulation (HCE), which eliminates the need for a secure element component in the mobile device itself. SE services can be provided by the network ("cloud"), or by trusted software. This support was announced for the KitKat (4.4) version of Android.

Software Interface

 * http://open-nfc.org/wp/ - Open-NFC project
 * This project appears to be a multi-OS driver for MicroRead hardware (but with a HAL for other chips)
 * libnfc
 * open-source project for accessing NFC features from user-space
 * Android APIs
