United Kingdom-based miiCard, a startup that helps you prove your identity online, announced a second round of seed funding for $2.5 million USD today. Investments came from a mix of groups including New Wave Ventures, IQ Capital and Par Equity.

The startup plans to use the funds to expand its digital passport technology. On its blog, miiCard mentions:
