This is a 45mm x 30mm white NTAG424 scratch tamper-proof label. The face material and structure of this tag is manufactured in a way that once applied, it will break apart when an attempt to remove is made. At which point, the antenna will be damaged and the tag will no longer scan.
This tag is particularly delicate to handle and care must be taken removing from the liner and applying.
Supplied in strips in lower quantities or on a reel in higher numbers.
This product contains the NTAG424 authentication chip. The encoding/programming of this chip for use with authentication is substantially more complicated than a normal NTAG213 chip and requires specialist software, a high level of technical knowledge and typically a back-end server programmed to verify authentication codes. You cannot encode these tags for authentication using a mobile phone.
This product is available as special order with unique ID print for visual identification if required. Please contact us for information and ordering.
Using NFC Tamper Labels
There are two main categories of NFC tamper labels - Destruct type (which stop working on tamper) and Detect type (which continue to work but can tell if a tamper has been made). Destruct labels have two sub-types : scratch and peel. Detect have two sub-types : break and capacitive.
Tamper tags don't like movement. They work best on firm, solid and non-flexible surfaces such as glass or rigid plastics.
Scratch tamper tags are designed to disintegrate on an attempt to remove. The tags must be attached to a smooth, clean surface. If you are testing, give the label plenty of time (ideally 24 hours) for the adhesive to get a good grip. An attempt to remove will chip away at the tag and destroy the antenna. These tags can be placed behind other labels.
Peel tamper tags have two layers which are designed to separate when an attempt is made to remove. The tags must be applied to a smooth, clean surface. As with scratch tags, give plenty of time for the adhesive to reach full strength before testing removal. On removal, the top layer will separate from the base layer destroying the antenna and preventing the tag working.
