NXP Near Field Communication
(NFC) for handheld devices and
POS terminals PN532
Making secure connectivity easy
NXP Semiconductors’ controller IC PN532 is a highly integrated transmission module
including a microcontroller which reduces the processing power from the host controller.
The PN532 offers proximity connectivity targeting 13.56MHz reader/writer applications for
POS terminals and handheld devices and is also capable of acting as a smart card when
combined with a secure element.
Key features
}
