I'd like to use it without recurring to polling

I'm using this library with PN532 and Raspberry Pi B+ but having trouble reading my cards. Here's the output I'm seeing when trying to scan.

Port:/dev/ttyAMA0
Found PN532 with firmware version: 1.6
Waiting for MiFare card...
Found card with UID: 0x23051749
Failed to authenticate block 0

The card is the one that came with the PN532 but I'm seeing the same with these cards as well.

I am using Python 3.6, when I trying to run the code, error below appear, please help. TQ

Traceback (most recent call last):

rx_info += self.ser.read(self.ser.inWaiting())

TypeError: must be str, not bytes

Does this depend upon a particular pin configuration?

According to a diagram I found for the RasberryPi 3 I am using, it seems like the following would be right

GPIO 8 > Tx (SDA)
GPIO 10 > Rx (SCL)

Thanks!!!
