UHF RFID File Tracking Label ID 73x21-M830 (Impinj M830, 73 × 20 mm)

A UHF RFID file tracking label sized for folder spines and cartons

The ID 73x21-M830 is a long, narrow UHF RFID label: 73 × 20 mm, with a 70 × 14 mm antenna running almost its full length. That shape fits the spine or edge of a file cover, a box file or the side of an archive carton, where it can be read without opening the file. It is a passive EPC Gen2 label, so it needs no battery and a UHF handheld moved along a shelf reads many files in one sweep.

Impinj M830 or Alien Higgs 10?

This label uses the Impinj M830, a chip from Impinj's M800 series. It has a 128-bit EPC and a 96-bit factory TID but no user memory, which suits file tracking systems that keep only the file or asset number on the tag. It is rated for 100,000 programming cycles and 10-year data retention, against 200,000 cycles and 50 years for the Higgs 10 version. This label, with the same antenna and roll format, is also offered on the Alien Higgs 10 chip with 32 bits of user memory as the ID 73x21-H10.

How a file tracking setup uses it

1. Register. Write the file number to the 128-bit EPC with a UHF desktop reader or RFID printer, and link it to the file record in your software.
2. Lock. Set the 32-bit password, which the M830 shares for access and kill, and lock the EPC so the number cannot be overwritten by mistake.
3. Track. Read files at the record room desk, at doorways with a fixed reader, and shelf by shelf with a handheld during audits.

For a complete record room setup, see the file and record room tracking guide and the RFID file tracking system range.

Roll format for printers

Labels come on a 3-inch core with an 85 mm liner, 25.4 mm pitch and 5.4 mm gap, with the 73 mm side running across the liner. Check your printer's media width and core size against these figures before ordering. The same label also serves office asset tags and carton labels, provided it is not applied directly to metal.
