• test strips are stored in a disposable container that is separate from the device, such as a handheld photometric or electrochemical meter, that measures the analyte of interest.
• a test strip is removed from the container, a sample of fluid is dispensed onto the strip, and the strip is inserted into the apparatus for analysis of the desired component. After analysis is completed, the test strip is extracted from the meter and the strip disposed.
• the information that the user enters into the meter is generally calibration information comprising, for example, a set of calibration parameters and/or a calibration number and/or other information that is used to adjust internal calculation settings in the meter.

Alternatively if it is desirable to protect the RFID device (22) from exposure to the contents of the container (2) then the RFID device (22) is optionally not affixed to the inner surface of an inner layer (14) of the container (2). Therefore, in certain circumstances it may be advantageous to locate the RFID device (22) within the inner layer (14), within the outer layer (12) or between the inner and outer layers as herein described.
• the RFID device (22) is located optionally between the outermost surface (18) of the container (2) and the innermost surface (20) of the container (2) such that where two or more layers are provided, the RFID device (22) is located between the outermost (18) surface of the outer layer (12) and the innermost surface (20) of the inner layer (14).
• Methods of manufacturing the body (6), enclosing mechanism (10) or base (8) of the container (2) or assemblies thereof are generally known in the art and are described, for example, in US patent numbers 5,911,937; 6,769,558; 4,783,056; 4, 812,116 and 5,723,085 the disclosures of which are incorporated herein by reference. The person of ordinary skill will understand that these methods can be readily adapted to include an RFID device (22).
• the container (2) may further comprise a label (30) that is affixed to the body (6), the enclosing mechanism (10) or the base (8) of the container (2).
• the label (30) is affixed to an outer surface of the container (2).
• the label (30) comprises an adhesive layer for affixing the label (30) to the outer surface of the container (2).
• the RFID device (22) is present in or on the label (30) (see Fig 19) or in the adhesive layer (see Fig. 20) of the label (30).
• the label (30) may further comprise other features such as information about the contents of the container (2).
• the label (30) covers partly or wholly the outer surface of an outer layer (12) of the container (2).
• the label (30) displays the calibration information of the test strip container (2). In such embodiments the user is generally provided with a visual means of comparing the calibration information on the label (30) with a reading on the meter that displays the calibration information.
• the container (2) is designed to store the test strips in an unsystematic manner or in a systematic manner.
• An example of a container (2) that is used to store strips in an unsystematic manner is a vial.
• the strips which are typically between about 10 and about 40 millimeters (mm) in length and typically from about 3 to about 10 mm in width, are placed in the vial that is longer and wider than the individual strips.
• the vial is from about 15 mm to about 50 mm in length, and from about 5mm to about 30 mm in width.
• the test strips are generally not orientated by any means other than the form of the cavity of the vial.
• An example of a container (2) that is used to store the vial in a systematic manner is a cartridge. Such a cartridge is a container (2) into which the strips are inserted in a systematic manner, for instance as a stack of strips.
• the container (2) may also be provided with a strip dispensing mechanism and a mechanism for urging the strips towards the dispensing mechanism.
• the container (2) may be stored within the analytical device.
• the container (2) may have a functional interaction with the analytical device for delivering strips to a testing position or it may not.
• test strips are for use in the measurement of analytes such as glucose or cholesterol, although other analytes can also be measured.
• Fluids that are of particular interest include biological fluids such as whole blood, or a fraction or derivative thereof, interstitial fluid, urine or sweat.
• Non- biological fluids that can be used with the test strips include control fluids of known analyte concentration that are typically used to check the performance of the analyte measuring apparatus.
• One aspect of the present invention relates to a method for reducing the risk that calibration information is entered incorrectly into a test meter, wherein a container (2) comprising an RFID device (22). having calibration information stored on a microchip that accounts for the performance variability of test strips present in the container (2), and a meter provided with a radio transmitter and receiver and a means for converting received radio signals into calibration parameters for the meter, are brought into close proximity, preferably within a distance of about 0 meters (m) to about 100 m, more preferably between about 0 m and about 0.1 m, whereupon a means of transferring the calibration information is actuated to transfer the calibration information as a radio or microwave signal from the microchip to the receiver .

• a meter provided with a radio transmitter and receiver and a means for converting received radio signals into calibration parameters for the meter is brought into close proximity to a container (2) of the present invention.
• the RFID device (22) of the container (2) stores calibration information that accounts for the performance variability of the strips present in the container (2), the calibration information stored on the microchip having previously been calculated at about the same time that the strips were tested during manufacturing.
• a means of transferring the calibration information is then actuated, such as a radio signal transmitting, receiving and processing circuit in the meter, which causes the calibration information to be transferred from the microchip to the receiver of the meter.
• the user therefore does not have to manually enter calibration information relating to the test strips in the container (2) into the meter.
