About Micro RFID Tags 

A micro RFID tag is a miniature version of a standard tag, designed for applications where space is limited or where discrete tagging is required. Despite their small size, these tags are capable of storing and transmitting data effectively, making them ideal for tracking small or high-value items such as electronics, medical devices, and luxury goods.

Micro RFID tags are also used in applications like inventory management of small components, anti-counterfeiting measures, and even animal tracking. Their compact form factor allows them to be embedded within products or attached to items inconspicuously, providing robust tracking capabilities without compromising on performance.

Using a micro RFID tag offers significant advantages in scenarios where space is at a premium or discrete tracking is essential. These tags, despite their small size, provide robust data storage and transmission capabilities, making them ideal for tracking small, high-value items like electronics, medical devices, and luxury goods.

Micro RFID tags are perfect for inventory management of tiny components, enhancing accuracy and efficiency. Their compact size allows for seamless embedding within products or inconspicuous attachment, providing effective tracking and anti-counterfeiting measures without compromising the aesthetic or functionality of the item. This makes micro RFID tags a versatile and powerful tool in various applications.

Temperature Test Summary
High-temperature resistance test - These tags were attached to a sheet of glass at raised temperatures for 10 minutes. Tags were then removed from the oven and tested for readability immediately.
Low-temperature resistance test - The Universal Mini tags were attached to a sheet of glass at low temperatures outdoors. Tags were then checked for readability with a Motorola handheld RFID reader. Tags survived and were readable for 19 hours in Iowa winter conditions with temperatures between -21 to -26°F with no signs of failure.
