ABSTRACT OF THE DISCLOSURE The system is for effecting transections, such as manual or mechanical delivery of commodities, services and money, while using identificands, such as credit cards, check cards, cards for automatic machines, coded tokens, keys and the like, provided with visually and/or mechanically readable identification and/or processing data, and while using a personal identification number for checking the title of the user of the identificand. Each identificand has inaccessibly incorporated therein a miniaturized integrated circuit (IC), in the form of a "chip", including plural memories for entry and storage of information therein, including identifying data and securing data. The memories for the identifying and securing data are chargeable only once, and at least the contends of the memory for the personal identi- fication number are available only within the identificand. The identificands are usable with either a checking device or an automatic machine including a source of potential, and the integrated circuit includes components activated, responsive to an input potential from the checking device or automatic machine, to effect internal checking of the identity and title of a user of the identificand. Input/output devices are included in the integrated circuit for establishing communication between the identificand and the verifying means. such as the checking device or automatic machine, and the identificand is constructed to prevent external access to the integrated circuit except through the input/output devices when connected to a verifier. A protective code, in the form of a random number, is entered into a first memory and simultaneously is printed on a concealed paper. The user also receives the printed protective code and enters the code into the identificand where it is compared with the stored protective code so that, upon a positive result of the comparison, a release signal is produced for further processing. The user then selects a completely optional personal identification number and enters the same into a second memory in the identificand through the use of an encoder. The first and second memories are provided with input gates which are automatically destroyed after entry, respectively, of the protective code and the personal identification number. Various other required information is then fed into other memories of the integrated circuit, through gates which are then destroyed so that the identificand cannot be initialized a second time.
