Have you noticed hotel room cards work differently? Some need inserting, some unlock with a tap, and others look plain but have hidden tech—these are three main types: magnetic stripe cards, contact IC cards, and proximity cards. Here’s a simple breakdown of their differences and why hotels pick each!

1. What Are the 3 Room Card Types?

- Magnetic Stripe Cards: Classic "Magnet" Style

One of the earliest designs, with a black magnetic stripe (like old bank cards) storing basic unlock data. Insert into the lock slot; the lock reads the stripe to open.

✅ Pros: Cheap, easy to make, mature tech.

❌ Cons: Easy to demagnetize (with phones/keys), low security (easy to copy), only basic functions.

Best For: Economy rooms in old hotels, temporary backup cards (e.g., cleaning cards).

- Contact IC Cards: Stable "Plug-In" Upgrade

Has small metal dots on the surface. Insert into the lock—contacts connect to the lock’s circuit to send detailed data (room number, check-in time, permissions). The IC chip stores more data and handles access logic (e.g., guest vs. staff rights).

✅ Pros: Higher security (encrypted chips), flexible functions, stable signal.

❌ Cons: Needs plugging/unplugging (wears out slots over time), less convenient than tap cards.

Best For: Mid-to-high-end hotel rooms, permission-based use (staff cards, long-stay guests).

- Proximity Cards: Modern "Tap-to-Unlock" Mainstream

No slots or metal dots—uses an internal RFID chip to communicate with the lock wirelessly. Hold 3–5cm near the lock’s sensor (by the doorknob) to unlock. Common frequencies: 125KHz (low) and 13.56MHz (high, faster, more compatible).

✅ Pros: Super convenient (no insertion), great for luggage-carrying guests, solid security (encrypted high-frequency chips).

❌ Cons: May fail near metal/strong magnets, needs induction - enabled locks (old locks need upgrades).

Best For: Most mid-to-high-end hotels, chain hotels, and B&Bs (prioritize guest experience).

2. Why Do Hotels Choose Different Cards? 

Hotel choices depend on 3 things: needs, lock equipment, and cost:

• Old Hotels/Temp Use: Magnetic cards are cheap—good for low-security, tight-budget spots (short-term rentals, event rooms). 

• Mid-to-High-End/Permissions: Contact IC cards store detailed access rights—ideal for strict management (long stays, staff-only areas). 

• Mainstream/Guest Experience: Proximity cards are quick to use—perfect for hotels wanting to boost guest satisfaction (business/family travelers).  

Some hotels mix types: proximity for guests, IC for staff, magnetic for backups (e.g., warehouses).
