CardMic snaps magnetically to the back of any phone and turns meetings, calls and on-site conversations into transcripts, summaries and action items. Triple-mic pickup, 32GB of local storage and 55+ hours of recording on a single charge.
No extra device to clip, charge or forget. CardMic attaches to MagSafe-compatible phones, slips into a shirt pocket at just 60 g, and starts recording with a single press — so client meetings, site visits and phone calls are captured without breaking the conversation.
Connect CardMic to the companion app over Bluetooth.
