Micro-SIM cards are cards in the smallest available format following ETSI TS 102 221. The Micro-SIM, also known as Mini-UICC, is half the size of SIM cards today. With a format of 12mm x 15mm only, the Micro-SIM can be used in small mobile devices.

Micro-SIM Adapters (also called Mini-UICC Adapters) are mechanical adapters which are converting Micro-SIM-Cards into the format of normal plug-in SIM cards, so that the Mini-UICC card can be also used in devices designed for normal plug-in sizes

MIFARE, an acronym for Mikron Fare Collection System, was invented by NXP Semiconductors. It is the worldwide most used contactless communication protocol within the Smart Card business. Originally, this protocol was used for ticketing in public transportation.
MIFARE is compatible with ISO/IEC 14443 and therefore operating within the proximity distance of 10 cm.

Mini-UICCs are cards in the smallest available format following ETSI TS 102 221. The 3FF SIM card, also known as MicroSIM, is half the size of SIM cards today. With a format of 12mm x 15mm only, the 3FF card can be used in small mobile devices.
