Though no one has ever discovered the Team's use of phone pairing, certain hackers and criminals are wary of the vulnerabilities posed by mobile phones.

The target typically does not receive notification that their phone has been compromised. Pairing is not possible if the target's phone is turned off, is already paired though Finch is capable of bypassing this limitation by disabling the other pairing, (“ Risk”) or if wifi and bluetooth are turned off. The program lists the numbers nearby phones and allows the user to choose which phone to pair with. However, their method of doing so is unknown and blocked Finch's program from working. HR once forced paired Hayden Price's phone. (“ Relevance”) Control used a phone cloning program against Senator Ross Garrison. While working for the ISA, Shaw used a similar program that had a different appearance than Finch's and mentioned SIM card cloning when used on a target. Rick Dillinger also used the program but his had a different interface, possibly because he worked with Finch in 2010 and may have been using an older version of the program. This indicates he can either recover the program quickly or replicate it. Finch can quickly implement the program on a just-bought pre-paid cell phone despite his equipment in the library having been compromised by Root's hack and him having to abandon all of his technology for protection.

Originally provided by Finch to Reese, the two have since passed the program on to Carter (“ In Extremis”), Fusco (“ Bad Code”) and Shaw (“ Nothing to Hide”).
