RFID Tag for Sample Rack

Abstract

A method and device for automatically storing information from a plurality of sample holders held in a sample rack 100. Each of the sample holders has an individual barcode thereon (104). An RFID tag 402 is affixed to the sample rack, the method performed by the processor 408 of the image capture device comprising; receiving an image of the barcodes from a camera 202, obtaining data associated with each barcode based on the image, establishing communication with the RFID tag via an RFID reader/writer 404 and transmitting the data to the RFID tag. The system may include a light source, use NFC communication, communicate with a host computer, read 1d and 2d barcodes and implement automatic antenna tuning, continuous signal level scaling and active wave shaping.
