This saves time and avoids errors in data access. The barcode sequences are unique for each ordered batch - each sequence is used only once. HPE thoroughly tests its precision-engineered, high-resolution barcodes using software from the HPE Automation Group to assess and ensure the performance of the barcodes in demanding, fast-paced data center environments. These labels are professionally applied in a clean environment to ensure 100% readability and accurate placement. For labeled cassettes with free numbering, 100% readability is guaranteed. They can be ordered online in packs of 20. Customers who value additional RFID security can integrate RFID transponders into each label at minimal cost. The RFID transponder is integrated on the back of the label with free numbering and offers advantages in tracking, verification, and security for all companies that use systems to track IT resources.
