- Sample IDs are created externally (i.e., pre-labeled barcode stickers or some other system)

Nearly lll all barcode scanners use pre-coded labels with a bar code identifying scheme based on your needs such that the scanner can read the labels which in turn mimics keyboard strokes for entry into other applications. Thus, data entry staff click on the sample ID field in StudyTRAX, and then scan the sticker to enter the correct ID. Some example vendors include:
- American Barcode & RFID (website), [[ 1-800-274-0324, ext: 1613]], approximately $600 to $900 (2012 price) for scanner and labels (about 4000 labels).
- Barcoding Inc. , (website) [[ 1-888-860-7226, ext: 161]], approximately $400 to $900 (2012 price) for scanner and user-defined labels (about 3000 labels).
