Abstract
A portable card writer for a card with a magnetic stripe provided thereon comprises a chassis, a drive mounted on the chassis for moving the card to and fro, guided along the chassis, a magnetic writing head mounted on the chassis, a magnetic reading head mounted on the chassis, and a printer for writing data in the card at a portion other than the magnetic stripe.
Claims11
A portable card writer for writing user supplied data on a card with a magnetic stripe provided thereon adapted to store constant data and user supplied data comprising:
- a chassis;
- driving means mounted on said chassis for moving said card forwardly and backwardly relative to the chassis;
- means for guiding said card along said chassis;
- a single magnetic writing head mounted on said chassis aligned with said magnetic stripe for writing during backward movement of said card user supplied data on said card;
- a single magnetic reading head mounted on said chassis adjacent to said magnetic writing head and aligned with said magnetic stripe for verifying, during forward motion of said card, constant data recorded on said card and for verifying said user supplied data written by said writing head during backward movement of said card, as said user supplied data is written by said writing head;
- and
- printer means for writing said user supplied data on said card at a portion other than said magnetic strip.
A portable magnetic reading and writing apparatus for use with a card having a magnetic strip comprising:
- an outer casing;
- a chassis provided in said outer casing;
- driving means mounted on said chassis for moving said card forwardly and backwardly relative to the chassis;
- means for guiding said card along said chassis;
- a single magnetic reading head mounted on said chassis for reading information recorded on said magnetic stripe;
- a single magnetic writing head having a wider track width than said magnetic reading head for writing information on said magnetic stripe, said magnetic writing head being mounted on said chassis adjacent to said magnetic reading head in the direction in which said card is moved;
- printer means for writing data on said card at a portion other than said magnetic stripe, said printer means being mounted on said chassis;
- and
- keyboard means for inputting information to be written on said card by said writing head and said printer means;
- means for controlling said driving means, said magnetic reading head, said magnetic writing head, and said printer means in response to operation of said keyboard means, wherein said magnetic reading head reads information recorded on said magnetic stripe during a forward movement of said card, information inputted by said keyboard means is written by said magnetic writing head on said magnetic stripe and by said printer means at said portion during a backward movement of said card, and said information written by said magnetic writing head being read by said magnetic reading head, during said backward movement of said card, for verification.
