A drawer full of business cards is a graveyard, not a network. Here's how to turn the stack into contacts you'll follow up with - without becoming a data-entry machine.

The value of a business card decays by the hour. Within a day you've forgotten which conversation it came from; within a week it's just a name and a title you can't place. The card was never the point - the context was.
Almost everyone has the drawer, the jacket pocket, or the elastic-banded stack. The cards sit there because of a quiet false promise: "I'll process these later." Later never comes, and even if it did, the cards have already lost the only thing that made them worth keeping. A card carries a name, a title, and a company - the printed, least-perishable facts. What it never carried was the conversation, and the conversation is the part that decays. By the time you get to the drawer, you have a row of strangers whose printed details you could have found on LinkedIn anyway. The system has to capture context before the card hits the drawer, or the drawer wins.
The single habit that turns cards into a system: the moment you pocket a card, add one line of context. Not at the hotel that night - now, while it's vivid. On the back of the card itself works (a pen and three words: "recycling, Lyon, kid starts school"), or a quick note on your phone keyed to their name. You're not transcribing the card; the card already has the printed facts. You're capturing the one human detail and the reason you'd follow up, because that's the part the card lacks and the part that makes a follow-up land. Three words in the moment are worth more than a perfect transcription a week late.
Write on the card
The lowest-tech, highest-leverage move at any event: keep a pen, and the second a conversation ends, scribble three words on the back of the card. Where you met, one human detail, and the reason to follow up. When you triage the stack later, those nine words are what tell you which cards are worth a relationship and which are recycling.
Within a day or two, sit down with the cards once and sort them into three piles. Worth a relationship - the few where there's a real reason or a genuine click; these become contacts with the captured context, a sensible cadence, and the open thread logged. Worth keeping the details - people you may want to reach later but don't need to actively maintain; capture their details and let them sit dormant, on file for when a reason arises. Recycle - the polite exchanges that don't need a thread; throw the card out without guilt. Most cards belong in the second or third pile, and that's healthy. The mistake is trying to actively maintain everyone, which guarantees you maintain no one.
Card scanners exist and they're useful for what they do: OCR the printed details into a contact so you don't type the email and phone number by hand. If you process volume, use one. But be clear about what a scan gives you and what it doesn't. It gives you the facts that were already going to be the easiest part. It does not give you the conversation, the reason to reconnect, or the human detail - the parts that actually determine whether you ever follow up. A scanned card with no context is a faster way to fill a database you'll never email. The scan is a convenience for the facts; the one-line context note is the work that matters, and only you can write it.
The keepers - the cards worth a relationship - need to leave the stack and land somewhere you'll actually return to, not a notes app you'll never reopen. This is where a personal CRM closes the loop: each becomes a contact with the captured context, a cadence so they don't decay to absent, and the open thread logged so the next message has a hook. Contact Book is built for exactly this: you log a sentence, set the rhythm, and the dashboard surfaces who's overdue, so the people worth a relationship don't quietly slide into the drawer after all. The card was always disposable. The context, kept somewhere durable, is what turns a stack of paper into a network you can actually use.
