An information processing system includes an information bearing medium and an information reading unit. The information bearing medium has a two-dimensional array of unit data zones. Marks are provided on some of the unit data zones so as to form a digital code. Mark patterns of any two Y-directional adjacent unit data zone strings based on the arrangement of marks in an X-direction differ from each other. The information reading unit generates a data string on the basis of a unit signal formed from a plurality of signals output from a group of detection units that detect the marks in synchronization and recognizes the digital code of the information bearing medium on the basis of a group of the data strings sequentially obtained from the array of the unit data zones.

An electronic seal includes a housing, a cover, at least one touch piece, and, a transmission mechanism. The housing has at least one through track, in which the through track is disposed on the bottom of the housing. The cover is disposed on the housing and covers the housing. The touch piece is movably disposed on the through track and is partially exposed out of the housing. The transmission mechanism includes a driving member, in which the driving member drives the touch piece to move along the through track when the driving member is actuated relative to the housing.

A method for manufacturing a card body for a chip card, includes the steps of: supplying a metallic base body with two opposite main faces and a circumferential peripheral face connecting the two main faces, wherein in the base body a module opening for receiving a chip module has already been produced or will still be produced in a module opening zone, and producing a slot on the peripheral face between the two main faces. The slot is formed from the peripheral face up to the module opening or up to the module opening zone. An entry angle (?) of the slot into at least one of the two main faces is not equal to ninety degrees with respect to the main face.
