Identification and traceability work in all sectors has become much more easy thanks to RFID technology, but its implementation can be very complex. How to choose the right RFID terminal for your applications? The terminal must be adapted to your activities and environmental constraints. RFID technology allows a large number of choices to best meet your needs. But how to make the best choice between all these possible options?
First of all, which frequency is the right choice?
Your tags/labels and your RFID terminals must be adjusted to the same frequency, to be able to communicate together.
There are 3 types of frequencies commonly used:
The frequency must be adapted to your needs and to the environment.
The low frequency is adapted to harsh environments with high water concentration or metal presence, such as animals, beverages or fruits traceability. The reading distance is very short, even requires a contact. Readers equipped with a LF RFID module can be used to read animal chips in particular.
High frequency also works in metal or high liquid concentration environments. It allows a short reading distance (about 1m depending on the environment). Common applications of HF are logistics, industry, medical and transport tickets.
This newer technology allows fast, multiple and long-distance reading at the same time. UHF can also operate in spite of constraints related to the presence of metal or to high temperatures. This technology is perfect for industrial environments , logistics, retail…
Some terminals can be offered with LF or HF or UHF technology and can be associated with other technologies such as barcode scanning.
A fixed or a mobile terminal?
RFID readers can take various forms depending on their uses. There are two main categories of terminals: fixed and mobile terminals.
Fixed RFID terminals
At AXEM Technology, we have identified 3 categories:
- Industrial readers
- Desktop readers
- Industrial antennas
Mobile RFID terminals
Thanks to mobile RFID terminals, objects no longer need to be moved, it is the terminal that moves. This technology provides more flexibility, speed and efficiency for users.
The mobile terminal is available with multiple accessories, applications…
There are several types of mobile readers. AXEM Technology classifies them into 3 categories:
- PDA & Smartphones
- Mobile readers
Which terminal meets your requirements?
Some terminals are specifically designed to meet the most common constraints such as protecting the device from water, dust and the risk of falling. These devices are then certified with a protection rating ranging from IP65 to IP68. These terminals are suitable for construction and public works or waste management, for example.
Readers can also respond to other constraints.
For example, in outdoor environment, the screen must be visible despite the sun, especially in the energy field.
In addition, in the defence environment, data are confidential. Access must therefore be protected by fingerprint or iris recognition.
In the case of applications in the metallurgical industry, the terminals must be able to withstand temperature shocks. The military standards MIL-STD-810G ensure their resistance.
