Hotel Room Card Customization Pitfall Avoidance Guide 2.0

Although a hotel room key card is small, it is the first impression guests have of the hotel—whether the door opens smoothly, whether it feels safe to use, and whether its design is tasteful, all are hidden in this thin card. However, many hotels often encounter problems when customizing room cards due to ignoring details: either guests complain that "the door can't be opened with the card", or the card gets demagnetized after a few uses, or there is even a risk of information leakage... 

This time, we have upgraded and launched "Hotel Room Card Customization Pitfall Avoidance Guide 2.0" to help you avoid 90% of common pitfalls. At the same time, we tell you quietly: if you choose the right supplier (like us), these pitfalls won't exist at all!

1. These customized traps really hurt every hotelier who has stepped into them!

· "Compatibility trap": The card gets stuck in the door lock but can't open the door

Many hotels, when customizing room cards, only focus on "having an attractive card face" but ignore the compatibility with the door lock system. For example, they choose a card with a high-frequency (13.56MHz) chip, only to find that their own door locks are low-frequency (125KHz); or they fail to confirm the brand and model of the door locks, resulting in the card "having no response when inserted". The consequences are: guests can't open the door with the card, the front desk is extremely busy, and the hotel's reputation plummets!

· "The durability trap": demagnetizes/breaks after a few uses

Low-cost room cards often cut corners - poor-quality chips make them prone to demagnetization (especially when near mobile phones or bank cards), the card body is thin and breaks easily when bent, and the printed room numbers/patterns fade after a few washes. Result: Guests' cards break after staying for two days, and they have to go to the front desk to get a replacement, making their experience utterly terrible!

· "Security Trap": Risk of Information Leakage or Replication

When some small workshops customize [products], they use unencrypted general-purpose chips to reduce costs, or randomly print sensitive information such as guests' names and room numbers (and even fail to erase residual data from the previous batch). The consequences are: the cards may be copied, guests' privacy may be leaked, and hotels may face legal risks!

· "Design trap": good-looking but not user-friendly

In pursuit of a "high-end feel," the card surface is designed to be cluttered (with the room number hidden in a corner), or made of reflective material (making it hard to see at night), or even the card itself is too stiff (making it difficult to insert into the slot). The result: guests spend a long time looking for the room number, and when inserting the card, there's a "click" as it gets stuck, instantly ruining their mood!

2. how to avoid pitfalls in professional customization? 4 key points that hotel professionals must know!

- First, confirm the "temperament" of the door lock: the chip, frequency, and protocol must match.

Be sure to provide the door lock brand, model, and parameters before customization (for example: What is the chip frequency? Is a special encryption protocol required?). Professional suppliers will directly match the original chip solution to ensure "card-to-lock opening" with zero errors!

- Choose "durable type" for the material: stable chip + tough card body + firm printing

· Chip: Choose industrial-grade encrypted chips (anti-demagnetization, anti-copying), with priority given to supporting dynamic encryption (data changes every time the door is opened); 

· Card body: PVC material is recommended (thickness ≥ 0.8mm, not easy to break), or environmentally friendly materials with a frosted texture (good anti-slip feel); 

· Printing: Use UV deep printing or laser engraving (room numbers/patterns are scratch-resistant and wear-resistant). Important information (such as the guest's name) can be designed to be erasable or updated regularly.

- Don't cut costs on secure encryption: guest privacy is the bottom line

It is imperative to require suppliers to use encrypted chips and clear the original data of the chips (to avoid residual information from the previous batch). For VIP room cards used for long-term accommodation, a "time limit" can be added (such as automatic invalidation after expiration) to further enhance security.

- Design "Guest-Centered": Good-looking and More Functional

· Room number: Place it in a prominent position on the card (such as the upper right corner/middle), with a font size of ≥8pt (so that both the elderly and children can see clearly); 

· Material texture: Avoid materials with excessive reflection (which make it hard to see at night), and the card edges can be rounded (to prevent scratching hands when inserting the card); 

· Additional information: Practical information such as the hotel service phone number and WiFi password can be reserved (printed in an inconspicuous place on the back, so that guests can check it at any time when needed).
