20090084839 | METHOD OF PACKAGING FINANCIAL TRANSACTION INSTRUMENTS, PARTICULARLY STORED VALUE CARDS - A method of packaging financial transaction instruments includes preparing a batch of cards, where each card is provided with a first piece of machine readable information, and where the cards in the batch are in an order. A batch of packaging blanks is prepared, where each packaging blank is provided with a second piece of machine readable information. Each packaging blank is provided with a third piece of machine readable information, which is recorded onto a magnetic stripe carried by the packaging blank. A card is picked from a first ordinal position in the batch of prepared cards. A packaging blank is picked from a position, corresponding to the first ordinal position, in the batch of prepared packaging blanks. The picked card in the picked packaging blank is enclosed if and only if a matching condition is verified between the first and second pieces of information is verified. | 04-02-2009 |
20090040116 | Electronic entity with magnetic antenna - The invention concerns an electronic entity comprising an electronic circuit and an antenna one part of which at least forms a conductive circuit connected to two ends of the electronic circuit. The projection of the circuit formed by the antenna and the electronic circuit in a plane which is substantially parallel thereto, forms an intersection-free line and the antenna includes a winding which extends over strictly more than one turn. | 02-12-2009 |
