GuardRFID provides three infant tag options, two of which are tamper detecting. The TotTag (TT-1) uses a light and temperature sensor to detect when the tag is removed from the infant, and the PPT-2 tag has a cut-band which can be sensed if it is cut. If the tag detects a tamper event, then staff members will be notified. The umbilical tag (UT-1) does not have built-in tamper detection; however, people are reluctant to interfere with the umbilical cord for fear of causing harm to the baby.
