NHS Covid 19 app
Posted , 1 user is following.
I am not totally convinced that this app will be so beneficial to all.
My concern is the roll, in which the smartphone Bluetooth is applied.
I understand that if you become within 2mts of a registered positive
tested person , who has put there information into the NHS app it will
then pair up with another phone which in turn will tell that person that they
have been in contact with a positive tested person. Problem I see is that
people may have to self isolate, on the phones information. There may
be no proof that these two phone owners have actually had physical or
biological contact. There might be an eight foot high garden fence between
them. The average range on a Bluetooth device is 10mts so what's to prevent
that the Bluetooth pairing is done at 6mts
Thanks
