The invention relates to a document (100) with sensor means (110), at least one antenna (106), a first processor (104), a second processor (108), storage means (112) and a switch (114). The first processor (104) is designed to communicate with a reading device (102) via the antenna (106). The switch (114) is designed to switch the antenna (106) between a first stable state, in which a communication is prevented between the first processor (104) and the external reading device (102), and a second astable state, in which a communication is possible between the first processor (104) and the external reading device (102). The sensor means (110) are designed to detect a first identification feature of a user of the document (100). The second processor (108) is designed to compare the first identification feature with a second identification feature which is saved in the storage means (112), wherein the second processor (108) is further designed to switch the switch (114) to a second state if there is conformity between the first identification feature and the second identification feature. |
