• Infineon’s OC1230 is less than 4mm^2, smaller than a grain of rice
• You can fit nearly 40 of them in one nano SIM, the smallest physical SIM card on the market
• Infineon says it could fit in wearables like smart glasses or rings

Infineon Technologies has unveiled the world’s smallest GSMA-compliant eSIM solution – with dimensions of just 1.8 x 1.6 x 0.4 mm, the OPTIGA Connect Consumer OC1230 is smaller than a grain of rice and reduces printed circuit board (PCB) space requirements.

For scale, it’s also 37 times smaller than the industry standard Nano SIM and 130 times smaller than a standard SIM.
