CardDeck resources bring together everything you need beyond the product itself: step-by-step guides, blog articles on digital business cards and QR codes, free card templates, free QR and barcode tools, a help center for account questions and an FAQ. Use guides to do a task, the blog to decide, and help to fix something.
- Guides: step-by-step instructions for one task.

- Free tools: QR, vCard, WiFi, barcode and email signature generators.

Where should you start?
Start with the resource that matches what you're trying to do right now.
- "I want to make something." Browse card templates or open the free tools to generate a QR code or barcode in your browser.
- "I need to do a task properly." Follow one of the step-by-step guides — creating a card, issuing IDs, running a batch.
- "I'm deciding between options." Read the CardDeck blog, where each article answers one question, such as static vs dynamic QR codes or paper vs digital cards.
- "Something isn't working." Go to the help center or the FAQ.

Help and FAQ

How do resources connect to the product?
Every resource ends with a next step. A blog post on QR codes points to the QR code generator; an ID card guide points to the batch generator and templates. If you start with a free tool and later want codes you can edit after printing, you can create the same code as a dynamic one in a CardDeck account.
Which resources help with printing cards and codes?
Printing raises the most questions, so several resources focus on it. For QR codes, the rule of thumb is a minimum of 2 × 2 cm, scaled to about one-tenth of the scanning distance, with a clear margin around the code. For ID and membership cards, the standard size is CR80 (85.6 × 54 mm). The ID card templates page covers portrait vs landscape and required fields, the help center has a checklist for codes that won't scan, and the blog explains when a printed code should be dynamic so it never needs reprinting.
