Abstract: A low-cost system comprising a pattern arranged to encode information and a decoder for decoding the information encoded in the pattern is described. In particular, the mechanism employs a capacitive sensing technique. Electrodes are arranged (or stimulated, during operation) to each generate an electric field, and sense disturbances on the electric field caused by the pattern when the pattern is positioned over the electrodes. The spatial arrangement of the pattern allows information to be encoded on a strip or surface and decoded by capacitive sensors arranged to detect disturbances caused by possible patterns. The resulting solution is cheaper and less complex than optical solutions, e.g., barcodes and optical barcode readers. The mechanism may be used in a glucose meter for encoding and decoding an identifier for distinguishing batches of glucose meter test strips.
