NFC Shield V2.0 - Compile Error: 'Serial1' was not declared in this scope

Hi - I have bought NFC Shield V2.0 and followed the instructions as in Wiki – but not able to get it working. I have an urgent project that relies on reading/writing NFC. Would really appreciate your helps on making this works.

Compile Error: ‘Serial1’ was not declared in this scope

I am not sure I have structured the library correctly. The instruction on Wiki is not that clear, and could use your guidance on more detailed instruction to ensure I get it right.

under C:\Program Files (x86)\Arduino\libraries
Seeed_Arduino_NFC-master

– PN532 (renamed from PN532-arduino)
— PN532
— PN532_HSU
— PN532_I2C
— PN532_SPI
— PN532_SWHSU

Below is the full error

ReadTag:12:24: error: ‘Serial1’ was not declared in this scope

I have the latest version and tried following the test code in # NFC Shield V2.0 - Error compiling for board Arduino Uno, but there is still the error.

ReadTag:2:10: fatal error: Seeed_Arduino_NFC.h: No such file or directory

#include <Seeed_Arduino_NFC.h>

      ^~~~~~~~~~~~~~~~~~~~~

compilation terminated.

exit status 1
Seeed_Arduino_NFC.h: No such file or directory

Here is the test code provided in that topic.

#include <SPI.h>
#include <Seeed_Arduino_NFC.h>
#include  <NfcAdapter.h>

PN532_SPI pn532spi(SPI, 10);
NfcAdapter nfc = NfcAdapter(pn532spi);


void setup(void) {
    Serial.begin(115200); // begin serial communication
    Serial.println("NDEF Reader");
    nfc.begin(); // begin NFC communication
}

void loop(void) {

    Serial.println("\nScan an NFC tag\n");
    if (nfc.tagPresent()) // Do an NFC scan to see if an NFC tag is present
    {
        NfcTag tag = nfc.read(); // read the NFC tag into an object, nfc.read() returns an NfcTag object.
        tag.print(); // prints the NFC tags type, UID, and NDEF message (if available)
    }
    delay(500); // wait half a second (500ms) before scanning again (you may increment or decrement the wait time)
}

@vithit What kind of board do you use? Arduino UNIO?

Maker UNO by CytronTech (based on Arduino UNO)

Thanks a lot in advance for your guidance to help me through this.
