Printing Method
Here are 3 professional printing techniques to bring your designs to life.- Silkscreen Printing: ideal for printing logos and icons. The colors are pure and it is suitable for projects that require bright colors, large areas of solid color, and high-contrast patterns.
- UV Printing: Bright colors, scratch-resistant, suitable for complex patterns and multi-color printing.
- Offset Printing：High color reproduction accuracy, suitable for complex multi-color designs.
Surface Finishes
We provide the following surface finishes to cater to different branding styles.
- Glossy Finish: Surface is smooth and shiny, with rich and bright colors.
- Matte Finish: Soft and non-reflective, with a premium touch.
- Frosted Surface: Similar to frosted glass, it is anti-slip and anti-fingerprint.
- Spot UV: Glossy coating on selected areas for emphasis and visual contrast.
- Hot Stamping (Gold/Silver): Shiny metallic effect, enhancing card’s texture and brand equity.
Functional Add-ons
Improve usability with functional features to match your application needs.
- Magnetic Stripe: Commonly used for access control, membership, or payment systems.
- Signature Panel: Ideal for cards requiring a signature space, such as staff or banking cards.
- Scratch-off Panel: Covers PINs or promotional codes for privacy and marketing.
- Hole Punch: Allows easy attachment to lanyards or clips, useful for ID badges.
Security & Personalization
Enhance brand exclusivity and anti-counterfeiting features for premium applications.
- Variable QR Code / Barcode: Custom unique codes for access, tracking, marketing, loyalty programs, etc.
- Serial / Embossed Numbers: Unique serial number per card, variable data.
- Laser Engraving Number: Non-erasable, enhance anti-counterfeiting level.
- Hologram: Enhance brand trust and provide strong anti-counterfeiting protection.
Custom Size
Besides standard CR80 cards (85.5×54mm), we also allow you to customize the shapes, thickness (0.2 – 0.8mm), and dimensions according to project needs.Custom RFID Chip
Choose the RFID chips by protocol, capacity, and functionality. We have chip with LF (125KHz), HF (13.56MHz), and UHF (860–960MHz) frequencies. Other chips are also available upon request.
