No, No and No. All such a system does is add ANOTHER LAYER of difficulties in accessing airside. Airport owners will embrace it as a labour saving device; 'no access App then no entry, period". This is analogous to the single point rental reference system where real estate agents now require that prospective renters sign up (at their own expense) for a standardised application form.
The outcome will be one more barrier to simple free access to airports.
First issue: lost or stolen phone - "call during working hours Monday to Friday" you are now grounded until Monday morning 9.00am etc.
Second issue: we make this compulsory at pilots expense and transfer the security costs for GA aircraft onto pilots and aircraft owners.

Third issue: Cost - which will slowly escalate as the system is adopted.
To put it another way, it is exactly the same as what has been done To accomodation renters it puts the entire cost of the application/security back on them - plus of course a commission to the f*&*ing blood sucking leaches who dreamed the system up in the first place.
To put it yet another way the complexity of suchansystem will increase the cost of security and reduce access to airports.
To put that yet another way, as a free replacement of the ASIC card or an RFID access all areas card then we are talking,but as an additional layer - no way.
