Can RFID tags be read through walls?
Passive RFID tags generally cannot be read through walls, especially those made of metal or concrete. Active RFID tags, with their longer read range, might be detectable through thinner walls, but this is not their typical use case.
How much data can an RFID tag store?
The amount of data an RFID tag can store varies depending on the tag type. Simple RFID tags might only store a unique identifier, while more advanced tags can store several kilobytes of data, including product information, manufacturing details, and sensor data.
Can RFID tags be used to track people?
Technically, yes, RFID tags can be used to track people, but this raises significant ethical and privacy concerns. RFID is more commonly used for access control and tracking assets rather than monitoring individuals’ movements.
Are RFID tags waterproof?
Some RFID tags are designed to be waterproof and can withstand exposure to moisture and liquids. However, not all tags have this capability, so choosing the right type of tag for applications where water resistance is required is important.
How do I choose the right RFID system for my needs?
Choosing the right RFID system involves considering factors like the required read range, the environment in which the system will operate, the type of objects being tagged, data storage needs, security requirements, and budget.

How long do RFID tags last?
The lifespan of an RFID tag depends on whether it’s passive or active. Passive tags, with no internal power source, can theoretically last indefinitely. On the other hand, active tags have a limited lifespan determined by their battery life, typically several years.
