Detecting an NFC Reader

This example shows that an NFC reader can be detected by any device with a PN7150 module included.

This library includes 9 examples that you can use to test the performance of the PN7150 module, of course, with any device that works under NFC:

• Detecting Readers : This example allows you to detect NFC readers. It can prevent information theft caused by card cloning.

• Detecting Tags : This example helps you find devices capable to work with NFC

• ISO14443-3A Reader / ISO14443-3A Writer : This example helps you to read or write in a ISO14443-3A (Tag Type 2 – T2T) block 5. These tags are proximity contactless cards working at 13.56MHz for different applications such as access control, public transport, and vending machines, among others.

• ISO15693 Reader / ISO15693 Writer : This example helps you to read or write in a ISO15693 block 8. These tags are better known as “Vicinity Cards” and can be read from longer distances than proximity cards (up to 1 to 1.5 m).

• Mifare Classic Reader / Mifare Classic Writer : This example helps you to read or write in a Mifare Classic block 4. Proximity cards and smart contactless cards developed by NXP Semiconductors.

• Peer to peer discovery : This example allows you to detect a P2P devices. Peer-to-peer mode establishes a two-way communication channel between a pair of NFC-enabled devices. When a user brings two devices close to each other, the two NFC chips establish a P2P connection and exchange data.
