The RFID tag /label is used for identification of manufactured products by visual ly reading the 24 -digit code, scanning the RFID embedded chip , or scanning the printed QR /barcode . It is the responsibility of the producer to supply RFID tags approved by the Department following the requirements of Section 1030 and place them on the products that are being manufactured. The producer manages the quality control and initial production information and assigns an RFID alternate ID. It is the producer’s respon sibility to manage tags placed on products and upload test results once complete. 1030 -2 MANUFACTURED PRODUCTS Place the RFID tag /label on manufactured products . When accepted, the RFID tag/label item 20 record will be updated. RFID tags/labels are identifiers for all manufactured products that must be scanned to find the approval status on the Field Inspection Report (FIR) or NCDOT vendor alternate ID found on the N CDOT APL prior to use . RFID tag /label parameters for use on all manufactured products are as follows:
A.Tag/ Label Copy The tag/label copy shall be block type lettering with the company name , NCDOT Facility Plant ID Number and company logo. All information shall be subsurface printed.
B.Colors Color of ink must be black on white background.
C.Serialization The b ar code and human -readable equivalent shall be subsurface printed. Code 128 in 24- character hexadecimal format shall be utilized. A QR /barc ode linking to the NCDOT vendor alternate ID found on the NCDOT APL shall also be subsurface printed on the label .
D.Adhesion Adhesives shall be non- proprietary and have a minimum 2 year above ground life span.
