A method of operating an automated transaction machine comprising: receiving, at an ATM, a token from a user; confirming, with the ATM, a personal identification number of the user; dispensing, with the ATM, banknotes to the user in response to said confirming; characterised by: at least partially disengaging (84, 102) a first component of the ATM from a remainder of the ATM after said dispensing, wherein the first component is positioned within a safe of the ATM during said dispensing and wherein the first component comprises one or more indicators that can be utilized, by a computing device of the ATM, to confirm a presence of the first component in the safe and/or whether the first component is properly positioned in the safe; altering (86, 104) the first component of the ATM to a condition that renders the first component non-conforming after said at least partially disengaging (84, 102) by removing at least one of the one or more indicators; re-engaging (88, 106) the first component with the remainder of the ATM after said altering (86, 104); and replacing (90, 108) a second component of the ATM after said re-engaging (88, 106), including electronically pairing the second component of the ATM with the computing device of the ATM, wherein said pairing is responsive at least in part to said altering (86, 104), wherein a failure to detect, by the computing device of the ATM, the at least one indicator of the first component is a prerequisite to electronically pairing the second component with the computing device. receiving, at an ATM, a token from a user; confirming, with the ATM, a personal identification number of the user; dispensing, with the ATM, banknotes to the user in response to said confirming; characterised by: at least partially disengaging (84, 102) a first component of the ATM from a remainder of the ATM after said dispensing, wherein the first component is positioned within a safe of the ATM during said dispensing and wherein the first component comprises one or more indicators that can be utilized, by a computing device of the ATM, to confirm a presence of the first component in the safe and/or whether the first component is properly positioned in the safe; altering (86, 104) the first component of the ATM to a condition that renders the first component non-conforming after said at least partially disengaging (84, 102) by removing at least one of the one or more indicators; re-engaging (88, 106) the first component with the remainder of the ATM after said altering (86, 104); and replacing (90, 108) a second component of the ATM after said re-engaging (88, 106), including electronically pairing the second component of the ATM with the computing device of the ATM, wherein said pairing is responsive at least in part to said altering (86, 104), wherein a failure to detect, by the computing device of the ATM, the at least one indicator of the first component is a prerequisite to electronically pairing the second component with the computing device. at least partially disengaging (84, 102) a first component of the ATM from a remainder of the ATM after said dispensing, wherein the first component is positioned within a safe of the ATM during said dispensing and wherein the first component comprises one or more indicators that can be utilized, by a computing device of the ATM, to confirm a presence of the first component in the safe and/or whether the first component is properly positioned in the safe; altering (86, 104) the first component of the ATM to a condition that renders the first component non-conforming after said at least partially disengaging (84, 102) by removing at least one of the one or more indicators; re-engaging (88, 106) the first component with the remainder of the ATM after said altering (86, 104); and replacing (90, 108) a second component of the ATM after said re-engaging (88, 106), including electronically pairing the second component of the ATM with the computing device of the ATM, wherein said pairing is responsive at least in part to said altering (86, 104), wherein a failure to detect, by the computing device of the ATM, the at least one indicator of the first component is a prerequisite to electronically pairing the second component with the computing device.
