Clamshell Card

A Clamshell Card (sometimes called a “clamshell proximity card” or “thick proximity card”) is a rugged and durable RFID access card typically used for long-term use in access control systems. The name “clamshell” comes from the manufacturing process: two plastic shells are fused together, enclosing the RFID chip and antenna inside, which makes the card thicker and more robust than standard PVC cards.

Typical characteristics of clamshell cards include:

Usually made of ABS, PET, or PVC with a thicker profile (e.g. ~1.8 mm to 3.0 mm or more)
Embedded RFID chip and antenna sealed within the card, protected from bending, moisture, abrasion
Often used in 125 kHz low-frequency (LF) proximity systems (such as EM, HID, etc.), though variants in other frequencies may exist
Typically non-printable or with limited printable surface (some have a writable area or slot for label)
Long lifespan, high durability, and good environmental resistance

Clamshell cards are a classic and reliable form of proximity card for physical access control systems, especially in scenarios that require stable performance over many years.

What are the applications of RFID cards?

Scenario	Use Case	Description
Physical Access Control	Office doors, gates, turnstiles	Cards are used to grant or deny entry based on ID and permissions
Employee ID / Badge	Staff identification	Often paired with printed visual ID or labels
Parking Access	Garage gates, parking lots	Cards control entry/exit permissions
Time & Attendance	Clock in / clock out systems	Cards used as staff tokens for attendance logging
Membership / Club Access	Gym, pool, clubhouse	Cards act as membership tokens tied to access privileges
Elevator Floor Control	Restricted floor access	Cards restrict elevator access to specific floors
Visitor & Temporary Access	Short-term access credentials	Cards can be issued to visitors or contractors
Integration with Multi-Technology Cards	Hybrid systems	Some clamshell designs can embed multiple technologies (e.g. proximity + biometric or magnetic stripe)

Why Choose Us To Custom Rfid Card

Why Choose Our Clamshell Card?

Strong Durability & Long Usage Life
We use high-grade materials and precision sealing so the card resists bending, moisture, and surface wear. This ensures stable, long-term performance in demanding environments.

Reliable Read Performance
Our clamshell cards are engineered for robust read consistency with mainstream proximity readers, reducing read failures and increasing system reliability.

Support for Multiple Protocols / Chip Variants
We can supply cards with EM, HID, or other 125 kHz proximity protocols (or even hybrid designs), optimized for compatibility with your access control system.

Custom Label / Overlay Options
Although full-color printing on thick clamshell bodies is often limited, we can provide custom overlays, label inserts, imprinting, numbering, barcode/QR, and laser etching options to suit visual ID needs.

Pre-Encoding & Testing
We can pre-program the card UID, write your access system credentials, test each card before shipping, and provide test reports to ensure you receive ready-to-use units.

OEM / ODM Flexibility
We can offer custom thickness, card dimensions, surface finishing, logo treatments, and packaging tailored to your brand or system requirements.

Cost-Effective for Bulk Orders
As an experienced manufacturer, we offer competitive factory-direct pricing, scalable production, and efficient logistics for large and repeat orders.

Quality Assurance & Warranty
Every card is subject to quality testing (electrical test, durability, environmental stress) before shipping. We also offer warranty support and replacement for legitimate defects.

Technical Support & Integration Assistance
We provide guidance on integration, reader compatibility, encoding setup, and troubleshooting to help you deploy smoothly.

FAQ

01. What frequency / chip types do your clamshell cards support?

Our standard clamshell cards support 125 kHz proximity (EM, HID-style) variants. If you require other frequencies or hybrid cards, we can discuss custom solutions.

02.Can you print custom visuals or logos on clamshell cards?

Because clamshell cards are thicker and encase electronic elements, full-body printing is limited. However, we can supply custom overlays, labels, UV printing on designated surfaces, numbering, or laser engraving.

03.What is the typical life expectancy of a clamshell card?

Under normal use, a well-manufactured clamshell card can last for many years (5–10+ years), depending on environmental conditions, handling, and reader alignment.

04.How much do you charge?

The price is depending on the quantities, printing crafts, etc. Please share your requirements then we can check the accurate price including freight for you.

05.What is the minimum order quantity (MOQ)?

Our MOQ depends on the specification (protocol, custom overlay, pre-encoding). For standard non-printed cards, the MOQ is relatively low (for example, 100 or 500 pieces). For customized prints and encoding, MOQ may be higher. Please contact us with your specifications.

06.What is the lead time for delivery?

For standard clamshell cards, the delivery time is typically 5–10 working days. For customized or printed/encoded cards, it might take 10–20 working days or more, depending on quantity and complexity.
