Abstract: 1329964 Banknote dispenser; checking validity; token of special form BURROUGHS CORP 27 Aug 1970 [9 Sept 1969] 44452/69 Headings G4M G4T G4V and G4X An item dispensing apparatus receives from a customer a security card carrying magnetically recorded data in scrambled form, decodes the scrambled data, and dispenses an item only when the card, together with further information entered into the apparatus by the customer, is deemed valid. As described with regard to a banknote dispenser, a customer inserts his security card into the dispenser through a slot (2) (Fig. 1, not reproduced). The customer enters a four digit personal number on a keyboard (3). After satisfactory security checks, card removal from the slot (2) triggers the dispensation of a plastics packet of banknotes. The plastics packet (12) (Fig. 9, not reproduced) is redeposited through a slot (5) (Fig. 1). If invalid, the security card is retained by the dispenser. The apparatus may be employed "on line", for updating the customer's account. Cash dispenser.-The cash dispenser comprises four stacks of packages (23) (Fig. 7, not reproduced), with an automatic change between empty and full stacks. The cash dispenser is inhibited during refilling of the stacks (23). Security card.-One surface of a security card carries an embossed control number (20) (Fig. 5, not reproduced), a printed designation of the issuing bank, the associated customer's name, and twenty labelled boxes. The boxes are punched or dimpled successively to indicate the number of times, up to twenty, that the card has been used. An arrow (29) and instructions indicate the direction of card insertion into a dispenser. The second card surface (see Fig. 6) carries four magnetic recording strips 31-34. Strips 31, 32 carry static data in scrambled form i.e. customer's account number, branch sort code number, cross check character, space code character, and detect code character. Strips 33, 34 carry dynamic data, in scrambled form i.e. check word, personal number, security card checks, supplementary personal number, date of last use of card, and number of times of use. Each card 19 may be used only once a day. A black arrow 35 contains a random application of a quantity of magnetic material. Only discrete magnetic spots positioned in a plurality of preselected rows or tracks are relevant. These spots are counted before the security card is issued, the number subjected to a mathematical transformation to arrive at two limit values, which with the transformation are coded in the magnetic strips 33, 34 (security card checks).  Bank voucher and printer.-A card reader (15) (Fig. 2, not reproduced) extracts data from an inserted security card. A main printer 64 (Fig. 13) records from the card tracks 31, 32 (Fig. 6) the branch sort code and the customer's account number on a dispenser-retained bank voucher (24) (Fig. 10, not reproduced). The control number (20) (Fig. 5), number of card uses, amount (ú10) and date of dispensation are also recorded. A back-up printer (21), (22) (Fig. 2) is provided in case of failure. If a security card is retained by the dispenser, the main printer prints a retention code on the associated bank voucher to indicate the reason for retention. Sequence of operations.-The following sequence is controlled by a number of microswitches. When a security card is presented to the banknote dispenser, it is stopped by an entrance gate until a magnetic head detects magnetic oxide in the strips 31-34 (Fig. 6), and the card dimensions have been verified. The card is then moved into the machine by a system of pinch rollers (14) (Fig. 2), and the "WAIT" sign illuminated. After twenty seconds, during which the elements of the checking system (see Figs. 11-13) are set or reset as appropriate, the "ENTER NUMBERS" sign is illuminated. On entry, the personal number is stored in a keyboard store 89 (see Fig. 12). A magnetic head 37 (Fig. 11) reads the static data from the card strips 31, 32 (Fig. 6) under the control of an oscillator system 142 (Fig. 13). After decoding by a decoder 49 (Fig. 11) the data is stored in a 6 x 16 register 53. The dynamic data in strips 33, 34 (Fig. 6) is then read by a magnetic head 41 (Fig. 11), decoded by a decoder 51, and stored in a 3-channel register 77. A microswitch operated by the security card indicates that reading is completed, and instigates print-out of the static data on a bank voucher by the main printer 64 (Fig. 13). Parity checks are carried out. The personal number read from the security card is fed from the register 77 (Fig. 11) to a comparator 98 (Fig. 12) for comparison with the entered number from the keyboard store 89. If the numbers do not correspond, then a number may be entered on the keyboard a second time. If the numbers still do not correspond, and/or were not entered within twenty seconds of the "ENTER NUMBERS" signal, an "invalid" signal is sent to a decision unit 102 (Fig. 13), the security card data is re-read by the magnetic heads 37, 41 (Fig. 11) and the numbers recompared, the card retained and the apparatus shut down. A "CARD RETAINED" sign is illuminated. If a "valid" result is signalled to the decision unit 102 (Fig. 13), the security card is held stationary and the date of last use signalled from the register 77 (Fig. 11) to a comparator 126 (Fig. 12) for comparison with the current date. Correspondence of the dates results in card retention On a "valid" date comparison (dates different), the magnetic data taken from the security card arrow 35 (Fig. 6) is validated by a comparator 146 (Fig. 12), and the number of card uses is registered by a counter 130 and examined by comparator 134. If the card is about to expire, the final box labelled twenty on the card is punched, and the card retained, dispensation also occurring as below. For non- expiry, the security card is moved in an outwards direction while a magnetic load erases the data from the strips 33, 34 (Fig. 6), and the counter 130 (Fig. 12) is updated by one. The oscillator system 142 activates the magnetic head 41 (Fig. 11) to re-record on the card the updated dynamic data after scrambling by a scrambler 116. Finally, a new punch is added to the labelled boxes on one side of the security card, the card entrance gate is opened if the decision unit 102 (Fig. 13) and a control unit 175 so instruct, and the "TAKE CARD" sign illuminated. Card removal operates a microswitch to start the currency dispenser motor for dispensation of a banknote package, followed by shutdown of the dispenser. The reading, recording, printing, information extraction from the comparators 98, 126, 134, 146 and money dispensing are controlled by a control unit 175 (Fig. 13). The amount of money issued can be selected (not further disclosed). Apparatus for verifying that the security card is valid, and the card itself, form the subjects respectively of Specifications 1,329,965 and 1,329,966 divided from this Specification.
