I am unable to adhesively stick tags to my assets. Is there still a way to detect if a tag is removed?

Sowmya,

Many RFID companies make tamper-evident RFID labels (view a list). Typically, such labels are applied to assets. If a label is removed, it breaks the antenna’s connection with the chip and the device thus no longer functions. This prevents the tag from being used on another item. You can set up software in a reader to alert you if a tag is not read, which would tell you that an item has either been tampered with or stolen.

HID Global recently introduced a seal tag designed to transmit even after a seal is broken (see Tamper-Evident Tag Transmits Whether or Not Seal Breaks). This is useful for, say, tracking jewelry cases, totes and other containers.
