How to compare each row from one dataframe against all the rows from other dataframe and calculate distance measure?

I have two different customer dataframes and I would like to match them based on Jaccard distance matrix or any other method.

df1

 Name     country            cost
    0    raj  Kazakhstan     23
    1    sam      Russia     243
    2  kanan     Belarus     2
    3    Nan         Nan     0

df2

   Name     country   DOB
0   rak  Kazakhstan   12-12-1903
1   sim      russia   03-04-1994
2   raj     Belarus   21-09-2003
3  kane     Belarus   23-12-1999

Output:

if the string comparison value is greater than >0.6, I would like to combine both the rows in the new dataframe.

Df3

    Name     country   Name  country     cost   DOB
0    raj  Kazakhstan   rak   Kazakhstan  23     12-12-1903
1    sam      Russia   sim   russia      243    03-04-1994
2  kanan     Belarus   Kane  Belarus     2      23-12-1999
