Chip Scanners are only issued to Chipped Operatives or those with extremely high SCLs. Each Scanner only works for nine seconds (three rounds) when the button is depressed and it requires about six seconds (two rounds) per target to identify whether they are chipped. The Scanner then requires one minute to recharge itself. The Scanner works on a similar wave length to the chip meaning that any chip within one metre and also the chip that is being scanned is slightly interfered with (in game terms your green display turns red for the duration). This change in colour is normally enough time for Station Analysis to identify who is using the Chip Scanner and who the target is (as in 9/10 of the time).

There are some chips which will alert the wearer without giving off a signal to a scanner

The rumour that all Stormers are chipped cannot be proven as they also fail to show up on the scanners.
