Card having retroreflective bar codes and a magnetic stripe
First Claim
Patent Images
1. A card having retroreflective bar codes comprising:
- (a) a card substrate;
(b) a first information recording portion formed of a retroreflective material portion of a predetermined pattern, for reflecting a beam of incident light, as modulated in intensity by the predetermined pattern, to a distance of several meters from the card; and
(c) a second information recording portion readable locally with respect to the card, the first and second information recording portions being provided on the card substrate.

Abstract
A card having retroreflective bar codes is comprised of a card substrate on which there are provided a first information recording portion formed of a retroreflective material portion of a predetermined pattern and a second information recording portion which can be read out from a nearby place. Also, a card having retroreflective bar codes is formed of recorded tracks comprised of retroreflective material portions and nonretroreflective portions which are formed on a heat distortion material formed of a retroreflective member or retroreflective material by a selective heating and distortion process in response to information to be recorded.

12. A security identification pass card system comprising:
-
a card substrate; a first portion formed of a retroreflective material portion of a predetermined pattern on the card substrate, for reflecting a scanning beam of incident light, as modulated in intensity by the predetermined pattern, to a sensor distant by several meters from the pass card, the first portion recording personal identification information of a bearer of the pass card, including the bearer'"'"'s name, position, and a person number; and a second portion formed on the card substrate, the second portion being readable locally with respect to the pass card by direct contact with the second portion, the second portion recording the personal identification information. - View Dependent Claims (13, 14, 15, 16)

18. A card having retroreflective bar codes comprising:
-
(a) a card substrate; (b) a first information recording portion formed of a retroreflective material portion of a predetermined pattern, for reflecting a beam of incident light, as modulated in intensity by the predetermined pattern, to a distance of several meters from the card and a light absorbing mechanical shutter positioned over the retroreflective portion, the shutter having a selectable pattern of light transmissive portions so that a retroreflective code pattern can be selectively formed; and (c) a second information recording portion readable locally with respect to the card, the first and second information recording portions being provided on the card substrate. - View Dependent Claims (19)
