Hello!thanks for reply.
The version of weigand is 26 bits but the password are 32 bits.

Do you have any idea/information/code to decode the output from the weigand 26 bits proximity encoder?

For eg.,if the card no. is 22428028, I found that the INT0 will change to low 11 times, INT1 will change to low 15 times & P1.0 1 time only.

Thanks & Regard
