ISSUER & UA, can someone explain?



The WhoCares software FunSoft Vi****ss v1.20 available from asks for 'ISSUER' and 'UA'. Is this information I am likely to find on the net or is it info you extract along with MKs etc etc from an original card? Can these 2 things be calculated or can random numbers be used? In fact, in the Vi****ss system, what are they exactly? Any help appreciated. Thanks. (PS. I am not asking for keys, just some explanation)
