Just scan the card front and back with a desktop scanner and make one note with front and back images in same note. I scan a full 8-1/2 by 11 sheet at one time with 12 business cards. I store mine in Evernote Windows. Text of business card is indexed automatically. Handwritten notes are not unless using print font. Store all cards in notebook titled Business Cards. Each card is one note with title name of person or business (or both) Also each card is tagged with class of business: travel, supplies, etc... Cards are available on my Android smartphone. Simple, fast and efficient.
