What does the CardDeck blog cover?
The blog covers how people and organizations share contact details and identity: digital business cards, QR codes, barcodes, NFC, employee and student IDs, event badges and membership cards. Articles are written for the person doing the work — the freelancer printing their first QR code, the office manager issuing staff IDs, the event lead with 600 badges to print by Friday.
Topics fall into a few groups:
- Business cards — paper vs digital, what to put on a card, and how teams keep details current.
- QR codes — static vs dynamic, print sizes, where to place codes so people scan them.
- Barcodes — choosing between Code 128, EAN-13 and UPC-A, and how check digits work.
- ID cards and badges — required fields, print specs, bulk generation and verification.
- Teams and events — templates, offboarding and turning badges into networking cards.
Which articles should you read first?
Start with the article closest to the decision in front of you.
- Printing a QR code on anything? Read static vs dynamic QR codes first. It explains why a dynamic code saves reprints and when a static code is fine.
- Choosing a code for a product, ticket or ID? Barcode vs QR code compares data capacity, scanners and use cases.
- Issuing staff or student IDs? How to make ID cards from Excel walks through preparing the spreadsheet, matching photos and exporting print-ready cards.
- Deciding whether to keep paper cards? Paper vs digital business cards compares cost, updates, sharing and environmental impact.

How are CardDeck articles written?
Each article answers a single question and puts the answer in the first paragraph, so you can stop reading once you have what you need. The rest of the article covers the detail: steps, sizes, examples and mistakes to avoid.
We name the standards behind technical claims — ISO/IEC 18004 for QR codes, GS1 for retail barcodes, ISO/IEC 7810 for ID card sizes, vCard for contact files — and avoid statistics we can't source. Product mockups in articles use sample names and companies. When a feature or price changes, we update the article rather than publishing a new one.
What is the difference between the blog, guides and help center?
The blog explains ideas and decisions; guides are step-by-step instructions for a task; the help center answers questions about using your CardDeck account. If you are deciding what to do, read the blog. If you know what to do and want the steps, use a guide. If something in your account isn't working the way you expect, go to help.
