The MFF2 (Miniaturised Form Factor 2) is a remarkably small SIM card, measuring just 6×5 mm, also referred to as a SIM chip. This SIM chip is essentially a sealed embedded SIM card that is directly attached to the PCB (Printed Circuit Board) of a device. This innovative design contributes to heightened security, reliability, and resilience, particularly in the face of shock, corrosion, and other environmental influences.

One of the key improvements offered by the MFF2 is the streamlined production process. Instead of the labor-intensive task of manually installing SIM cards, a roll of SIM chips is loaded into a pick and place robot during production, which then precisely positions the SIM chip on the PCB. This not only saves time and effort but also adds to the overall efficiency of the manufacturing process.

The benefits of the MFF2 extend beyond the production phase. Its advantages include cost reduction, conservation of PCB space, elimination of the need for configuration and stock management, and enhanced protection against various environmental factors. Furthermore, from an environmental perspective, the MFF2 is more eco-friendly compared to traditional plastic SIM cards. Lastly, the MFF2 also boasts a longer lifespan when compared to plastic SIM cards, making it a compelling choice for manufacturers seeking durable and reliable components for their devices.
