New submitter mk1004 writes "ETSI members have approved a new, smaller SIM format. 'The fourth form factor (4FF) card will be 40% smaller than the current smallest SIM card design, at 12.3mm wide by 8.8mm high, and 0.67mm thick. It can be packaged and distributed in a way that is backwards compatible with existing SIM card designs. The new design will offer the same functionality as all current SIM cards.' Nokia is not happy about the decision, as they believe their version was superior, but they say they're prepared to license the patents essential to the standard."
