SolarCard / solar business card

SolarCard
SolarCard

Since business cards leave lasting impressions, people want their cards to be more special. SolarCard is an interactive business card with Flexible Thin Film Solar Cell that can operate film speaker and flexible display to express one’s identity more dynamically. When touched, SolarCard reacts to play unique tunes and display multi-lingual messages or images on the front display. SolarCard can deliver amusement and impression as well as a variety of information. Since Flexible Thin Film Solar Cell can be easily attached to card materials and can provide enough voltage while occupying only a small portion, cards can still be designed freely.
