The environmental conditions that the UHF RFID tag may encounter during its lifetime are major considerations in tag selection. A tag embedded within the product may encounter high temperatures and pressures during product manufacturing, and it must be able to survive those conditions. Evaluate environmental conditions not only within your own facility but also in any environment the tag will travel through during its entire lifetime. These environmental conditions may affect the tag's read range or read rate:
* The substrate may absorb moisture or may become brittle and crack.
* The adhesive may not hold the tag due to moisture or chemicals and the tag may fall off the item.
* The interconnection between the antenna and the IC may break due to vibration or due to repeated flexing of the tag.
* The antenna may be weakened due to corrosive effects of the chemicals in the environment.
You may need to use encapsulated tags that are protected from abrasion or chemicals in the environment.
