Can we read transaction details like amount once nfc payment is done?

I'm not sure about it.
The AIP (tag 82 which is part of GPO R-APDU) consists of 2 bytes, of which the second byte is RFU, while the first byte encodes the stages of the EMV debit/credit transaction flow and the corresponding application functions that are actually supported by the card.
I noticed the you implemented it in reverse. am I wrong ?
private static final byte[] GPO_COMMAND_RESPONSE = {
(byte) 0x80,
(byte) 0x06,
(byte) 0x00,
(byte) 0x80, /* this should be RFU */
(byte) 0x08,
(byte) 0x01,
(byte) 0x01,
(byte) 0x00,
(byte) 0x90, // SW1
(byte) 0x00 // SW2
};

30 private static final DateFormat timeStampFmt = new SimpleDateFormat("HH:mm:ss.SSS ", Locale.US);

does this mean that only US cards will work, or that it will only work in the US
I live in Canada will my Canadian card work with your app in Canada?

Why did you remove track 1 support? It's necessary for most POS systems otherwise it will give card error.
