Methods of increasing coding information for biosensors and devices for same

A biological measuring device adapted for use with a test strip, wherein said test strip has at least a first contact pad and a second contact pad, and wherein said first contact pad has a first length and said second contact pad has a second length, said device comprising:

• a code reader having at least a first metal pin and a second metal pin,
• wherein said code reader is capable of reading coding information associated with said test strip based on a movement of said test strip before said test strip is placed still in relation to said code reader for a proper reading of a sample, and wherein said first length or said second length determines said movement.

A method of verifying coding information associated with a test strip adapted for use with a biological measuring device, said test strip having a substrate and a plurality of contact pads provided on said substrate, and said biological measuring device comprising a code reader having a plurality of metal pins corresponding to said plurality of contact pads, said method comprising:

• assigning a parity bit to one of said plurality of contact pads;
• determining said coding information by counting the number of a logical value generated when said plurality of contact pads are electrically coupled to said plurality of corresponding metal pins;
• comparing said number of said logical value against a predetermined number for said logical value, and if said number of logical value matches said predetermined number for said logical value, then said coding information is correct.

A test strip adapted for use with a biological measuring device, said biological measuring device comprising a code reader having a plurality of metal pins, said test strip comprising:

• a substrate;
• a reaction region formed by at least a first electrode and a second electrode provided on said substrate at one end, said reaction region is applied with an enzyme so that an electrical response is generated when said enzyme and a test sample form a chemical reaction, and
• a plurality of contact pads provided on said substrate, wherein a first and second contact pads of said plurality of contact pads are provided on said substrate at the other end to couple to a respective metal pin to output coding information associated with said test strip, and wherein a third contact pad of said plurality of contact pads is assigned with a parity bit to verify said coding information.

A biological measuring device adapted for use with a test strip, said test strip having at least a first, a second and a third contact pads, said device comprising:

• a code reader having at least a first metal pin and a second metal pin,
• wherein said code reader is capable of reading coding information associated with said test strip based on a movement of said test strip before said test strip is placed still in relation to said code reader for a proper reading of a sample, and
• wherein said code reader verifies said coding information using a parity bit assigned to said third contact pad provided on said test strip.
