Mooltipass is composed of one main device and a smartcard.
On the device are stored your AES-256 encrypted passwords. The smartcard is a read protected EEPROM that needs a PIN code to unlock its contents (AES-256 key + a few websites credentials). As with your credit card, too many tries will permanently lock the smart card.
The mooltipass main components are: a smart card connector, an Arduino compatible microcontroller, a FLASH memory, an OLED screen and its touchscreen panel. The OLED screen provides good contrast and good visibility.
It was a pain to import my 300+ passwords from my keepass database to the mooltiapp, finally i used 'Actiona' to automate the insertion thing.
I use the mini since 3 weeks now, a bit hard to leave my old habits of keepass, but very nice.
