Magnetic card reader
First Claim
Patent Images
1. A magnetic card reader which reads magnetic cards having a plurality of formats comprising:
- a format processing means including;
first format processing means operable to process a magnetic card based on a first format to check whether the encoded data on the magnetic card is recorded in the first format;
second format processing means operable to process the magnetic card based on a second format to check whether the encoded data on the magnetic card is recorded in the second format, wherein the magnetically encoded data in the first or second format is recorded on a magnetic stripe and includes a start code, data, end code and a check code, the first and second formats being different from each other;
a format processing pattern establishing means which selects said first format processing means or said second format processing means according to an indication command sent from a host machine which indicates which format to process by said format processing means; and
a format determining means which determines whether said indicated format and the format read from the magnetic card are consistent in accordance with the result of said format processing means, then sends the result of the determination to said host machine.

Abstract
A magnetic card reader to read magnetic cards having either a first or a second format for the magnetic data on a stripe. The reader includes a first and second format processor for first and second patterns, a format selector to select one of the two format processor in accordance with a selection or indication command from a host computer. A format determinator determines if the format read out from the card is consistent with the indicated format.

6. A magnetic card reader which reads magnetic cards having a plurality of magnetically encoded formats, comprising:
-
a first format processor operable to convert magnetically encoded card holder data encoded in a first format;
a second format processor operable to convert magnetically encoded card holder data encoded in a second format;
a form at selector operable to select the first format processor or the second format processor according to a format indication command from a host machine which indicates which format to process; and
a format determinator operable to determine whether the indicated format from the host machine and the format converted by the selected format processor are consistent, the format determinator further operable to send the converted card holder data to the host machine if it is determined that the indicated format and the converted format are consistent, to relieve the host machine from the format conversion. - View Dependent Claims (7, 8)
the format determinate r sends an indication to the host machine indicating that the conversion process by the selected format processor was unsuccessful;
the format selector receives another format indication command from the host machine indicating selection of a format processor which is different from the previously selected format processor; and
the format selector selects the format processor according to the another format indication command.

9. A magnetic card reader which reads magnetic cards having a plurality of magnetic formats comprising:
-
first and second format processors operable to process magnetic cards containing magnetically encoded data in first and second magnetic formats, respectively;
a format processing pattern establishing device coupled to the first and second format processors and controlled by a host machine that is remotely located from the magnetic card reader, the format processing pattern establishing device operable to;
receive from the remotely located host machine an indication command that instructs the format processing pattern establishing device which magnetic format to process, and select the first format processor or the second format processor according to the received indication command; and
a format determinator which determines whether the indicated magnetic format and the magnetic format read from a magnetic card are consistent, then sends the result of the determination to the remotely located host machine.
