SKU: NFC_PN7161_I2C Category:

The PN7161 NFC RFID Module is an enhanced version of the PN7160, adding support for Apple’s Enhanced Contactless Polling (ECP). It is otherwise identical to the PN7160 in hardware and software — same I2C interface, same dimensions, same driver support. If you need Apple Wallet, Apple VAS, or Apple ECP compatibility, the PN7161 is the correct choice.

PN7161 vs PN7160 — Key Difference

Feature PN7161 PN7160
Apple ECP (Enhanced Contactless Polling) ✅ Supported ❌ Not supported
Apple Wallet / Apple VAS ✅ Compatible ❌ Not compatible
All NFC Forum modes ✅ ✅
Linux / Android driver (libnfc-nci) ✅ ✅
I2C interface ✅ ✅
Dimensions 42.83mm × 40.53mm 42.83mm × 40.53mm
NCI 2.0 ✅ ✅

If your application does not require Apple ECP, the PN7160 is the equivalent lower-cost option.

Frequently Asked Questions

What is Apple ECP?
Enhanced Contactless Polling (ECP) is Apple’s protocol that allows iPhone and Apple Watch to automatically activate the correct NFC application when approaching a compatible reader — used in Apple Wallet passes, transit cards, and Apple VAS (Value Added Services).
Can I replace a PN7160 with a PN7161?
Yes. The PN7161 is a drop-in replacement for the PN7160 — same pinout, same dimensions, same driver.
Do I need PN7161 for general NFC reading?
No. If you don’t need Apple ECP, the PN7160 is sufficient and typically lower cost.
Does it work with the linux_libnfc-nci driver?
Yes. The same NXP Linux driver that supports PN7160 also supports PN7161.
