If so, what type of tag would be best suited for this application, considering the function that shackles serve?
Omni-ID and Holland 1916 have developed a passive ultrahigh-frequency (UHF) tag, known as the 360°, specifically designed for shackles, slings and other industrial equipment. The tag is encased in an industrial steel frame with a tether attachment that can be affixed to lifting equipment (see Omni-ID Debuts Tags for Oil and Gas Companies).
In addition, InfoChip offers small Near Field Communication (NFC) tags that can be embedded in slings, shackles and so forth. The tags have a short read range, but they have the advantage of being capable of being read by any mobile phone equipped with an NFC reader and a special add-on antenna created by InfoChip (see InfoChip Markets Signal-Boosting Add-on HF Antenna and RFID Phone App).
