What Is a CR80 Card? Is It the Same as an RFID Card?
If you've ever used a keycard to enter an office, swiped a loyalty card at a store, or even checked into a hotel, you've probably held a CR80 card. But what exactly is it, and how does it relate to RFID cards?
Let's break it down in simple terms—no technical jargon, just clear explanations.
1. What Is a CR80 Card?
A CR80 card is the standard size for plastic cards used in ID badges, membership cards, and access control systems. The name comes from its dimensions:
- Width: 85.6 mm (3.37 inches)
- Height: 54 mm (2.125 inches)
- Thickness: 0.76 mm (0.03 inches)
This size follows the ISO/IEC 7810 ID-1 standard, the same dimensions as credit cards, driver's licenses, and most RFID cards.
Common Uses of CR80 Cards:
- Access control cards (office buildings, hotels)
- Membership & loyalty cards (gyms, retail stores)
- ID badges (employee, student, or event passes)
- Gift cards & prepaid cards
2. Is a CR80 Card the Same as an RFID Card?
Short answer: No, but they often overlap.
Here's the key difference:
| Feature | CR80 Card | RFID Card |
|---|---|---|
| Definition | A standard size for plastic cards | A card with embedded radio-frequency technology |
| Technology | Can be blank, magnetic stripe, barcode, or RFID | Always contains an RFID chip & antenna |
| Usage | Physical size standard | Wireless communication method |
How They Work Together:
- Many RFID cards are made in the CR80 size (e.g., hotel keycards, contactless payment cards).
- But not all CR80 cards have RFID—some are just plastic with a barcode or magnetic stripe.
3. Types of CR80 Cards: Which One Do You Need?
Since "CR80" refers only to the size, the card's function depends on its technology:
Plain PVC Cards
- Just a blank plastic card (no tech)
- Used for custom printing (e.g., event badges)
Magnetic Stripe Cards
- Has a black magnetic stripe (like old credit cards)
- Stores data but requires swiping
RFID Cards
- Contains an embedded chip & antenna
- Works wirelessly (tap-to-scan)
- Common types: 125 kHz (Prox), 13.56 MHz (MIFARE, NFC)
Smart Cards (Chip & PIN)
- Contains a microprocessor (like EMV bank cards)
- More secure than RFID for payments
4. Why Does the CR80 Size Matter?
The CR80 standard ensures compatibility with:
- Card printers (for custom designs)
- Card readers (swipe, insert, or tap)
- Wallets & holders (fits like a credit card)
If a card isn't CR80, it might not work in standard equipment.
5. How to Choose the Right CR80 Card
Need just a basic ID badge?
→ Go for plain PVC or magnetic stripe.
Need wireless access control?
→ Choose RFID (Prox or MIFARE).
Need high-security payments?
→ Look for smart chips (EMV).
Final Verdict: CR80 vs. RFID
- CR80 = Size standard (like "letter size" for paper).
- RFID = Technology (like "inkjet vs. laser" printing).
Many RFID cards are CR80, but not all CR80 cards have RFID.
