Very loosely I can see some connect between Home Affairs and State Security.... were there not a separate State Security apparatus. Not so as it is currently proposed. Neither do I see any justification for allowing BMA / Home Affairs receiving their own income stream from Customs and Excise. 
An enhanced ID data base is fine, but not to the extent it interferes with day to day issues.... and a modest fee is not so much the issue as is the extension of State into our private lives. 
Will it actually work... that's another issue!
