From Keys to Cards: The Tech Transition That Opened New Doors in 2021

Misplaced metal keys, tricky locks, and juggling luggage at the door—these are the small frictions that can slow down an otherwise perfect arrival. In late 2021, De Zeeuwse Stromen went from keys to cards, completing a hotel-wide upgrade from mechanical keys to RFID keycards. The result: faster access, smarter security, and a meaningful step forward for sustainability—across every accommodation, from the main building to the Dune Park.

In this post, you’ll learn what changed, why it matters for guests and meeting planners, and how this transition supports the hotel’s broader commitment to a greener stay.

Why move from keys to cards?

Switching from keys to cards is about more than swapping metal for plastic. It’s a foundation for better hospitality:

Guest convenience: Tap-and-go access is quicker and more intuitive—especially helpful when you arrive with full hands.
Security, simplified: Modern locks enable smarter safeguards to ensure doors are properly closed.
Smarter access control: Specific areas—like wellness facilities or meeting rooms—can be made accessible only to the right guests.
Sustainability in action: Keycard holders help prevent unnecessary energy use by switching lights off when the card is removed.

Industry-wide, RFID hotel systems are prized for durability and ease of use, as they don’t rely on magnetic strips and are less prone to demagnetization. They also support flexible access management, which is why so many hospitality brands adopt them.

What changed at De Zeeuwse Stromen in 2021

De Zeeuwse Stromen completed a property-wide locks modernization in late 2021. Here’s what that means for your stay:

RFID keycards replaced mechanical keys: The former mechanical room keys made way for a new hotel locking system. From now on, you simply open the door with a keycard—fast and fuss-free.
Easier arrivals with full hands: The keycard makes unlocking straightforward when you’re carrying a bag or returning with towels from the beach.
Built-in safety alerts: Each lock is equipped with an alarm function—the lock will emit a signal if a door is not properly closed.
RFID convenience, no magnet worries: The cards use RFID (radio-frequency identification) and are insensitive to magnetic fields, so you can safely keep your card in a wallet.
Facility access, tailored: Each keycard can be configured in advance to grant access to specific facilities such as the pool and sauna.
Ideal for meetings and events: For business groups, access can be set per participant to particular rooms or meeting spaces—perfect for moments when a room is locked during lunch or breaks.
Energy-wise lighting: With the card in the in-room holder, the lights come on; remove it, and lighting turns off. This pairs with the hotel’s 100% switch to energy-efficient LED light sources to help avoid unnecessary energy use.
Unified experience across accommodations: All accommodations—in the main building and the Dune Park—now use modern electronic keycards.

The bottom line for guests

Faster, easier room access
Visual and audible reassurance if a door isn’t fully closed
Hassle-free card storage (keep it in your wallet)
Access to wellness facilities managed via your card
Lights that work only when your card is in the holder for energy-conscious comfort

Sustainability that you can see—and use

The keycard transition supports a broader sustainability approach at De Zeeuwse Stromen:

LED everywhere: The hotel has made the 100% switch to LED light sources, dramatically improving energy efficiency compared to traditional lighting.
Keycard holder = fewer wasted watts: The in-room keycard switch ensures lights are on only when you’re inside. Remove the card, and the room powers down lighting—simple, automatic savings without compromising comfort.
Green Key Gold mindset: The property’s Green Key Gold certification reflects conscious, daily choices that reduce environmental impact. Simple guest habits are part of this too: if your towels are still unused, leave them hanging so they are not washed unnecessarily.

Together, these measures turn small moments—like opening your door or turning on the lights—into meaningful steps toward a greener stay.

Better access for meetings and groups

If you’re planning a training, meeting, or multi-room event, from keys to cards unlocks practical advantages:

Room-by-room permissions: Assign who can enter which meeting room(s) and when.
Secure breaks: Keep a room locked during lunch or overnight, with access only for designated participants.
Smooth guest flow: Manage wellness access (e.g., pool, sauna) via participants’ cards, supporting a clear, easy-to-understand program.

Pair these access tools with the hotel’s broader facilities—including wellness and the on-site restaurant—for a seamless event experience.
