A writing instrument includes a shaft barrel and a grip provided at part of the shaft barrel. The grip has a cylindrically shaped inside shaft part and a cylindrically shaped outside shaft part arranged at the outside of the inside shaft part, thinner than the inside shaft part, and made of a nonviscoelastic plastic. A space part is provided between the inside shaft part and the outside shaft part.

A computer-implemented method includes: obtaining, by a computing device, an original Personal Account Number (PAN) to be transformed; transforming, by the computing device, the original PAN to form a transformed PAN; performing, by the computing device, a verification on the transformed PAN; determining, by the computing device, whether the transformed PAN passes verification; and storing or outputting, by the computing device, the transformed PAN based on determining that the transformed PAN does not pass verification, wherein the original PAN is later recovered from the transformed PAN to process a transaction.

Altering account numbers into invalid account numbers for secure transmission and storage

A handwriting input device configured to obtain hand-written data of an electronic pen on a coordinate detection surface of a coordinate input device by an electromagnetic induction effect of the coordinate input device and the electronic pen. The electronic pen includes a first resonance circuit including a coil, a capacitor, and a core, a mechanical pencil unit configured to perform writing on a paper sheet placed on the coordinate detection surface, and a writing pressure detecting portion configured to detect a writing pressure such that a part of the mechanical pencil unit is pushed by receiving the writing pressure applied to a lead projecting from a distal end of the mechanical pencil unit. The detection of the writing pressure causes the coordinate input device to obtain the hand-written data corresponding to a handwriting on the paper sheet while writing is performed on the paper sheet with the electronic pen.
