The Production Process of Smart Cards: A Complete Guide

Smart cards, also known as integrated circuit cards (ICC), are portable devices embedded with microchips, antennas, or magnetic strips. They are widely used in identification, payment, access control, transportation, healthcare, and telecommunications. Below is a standard industrial production process for contact/contactless smart cards, from raw materials to finished products.

The base material determines the card’s durability, printability, and lamination performance. Common materials include:

• PVC: Most widely used for ID cards, bank cards, and membership cards.
• PET / PET-G: Eco-friendly, heat-resistant, suitable for digital printing and high-temperature environments.
• ABS: High mechanical strength, used in heavy-duty access control cards.

Standard sheet thickness is usually 0.15mm–0.8mm, prepared in large sheets for printing and lamination.

Card surfaces are printed with graphics, barcodes, QR codes, personal data, and brand identity.

• HP Indigo & other digital presses: Suitable for on-demand, variable-data printing.
• Offset printing: Used for large-volume, high-resolution full-color jobs.
• Printable coated sheets ensure strong ink adhesion and clear image quality.

Contactless cards rely on RFID/NFC technology:

• An etching or printing antenna is placed on the inlay sheet.
• A microchip module is bonded or welded to the antenna circuit.
• The inlay is tested for frequency, signal strength, and chip function.

Contact cards use contact-based chip modules exposed on the card surface.

Multiple layers are fused into a single rigid card under high temperature and pressure:

• Top overlay film (protective, transparent)
• Printed outer layers
• Core layer with chip inlay
• Bottom overlay film

Lamination ensures waterproofing, bending resistance, and tamper protection.

The laminated large sheet is cut into standard ID-1 format cards:

• ISO 7810 standard size: 85.60 mm * 53.98 mm
• High-precision die-cutting machines ensure consistent dimension and edge smoothness.

Cards are programmed and customized for end users:

• Chip encoding: Write data, keys, and application files.
• Magnetic stripe encoding: For traditional magnetic stripe cards.
• Laser engraving: QR codes, serial numbers, portraits.
• UV printing / hot stamping: Security features and variable data.

Each batch undergoes strict inspection:

• Visual check: printing, lamination defects, scratches.
• Electrical test: chip reading, antenna signal, communication stability.
• Mechanical test: bending, torsion, temperature resistance.
• Security check: anti-counterfeiting features validation.

Qualified cards are packaged in anti-static bags or boxes, with protective separators to avoid scratching. They are then delivered to system integrators, governments, enterprises, or financial institutions.

Smart card production combines material science, precision printing, electronics, and security technology. High-quality base sheets, stable lamination, reliable chip implantation, and strict testing together determine the performance and service life of smart cards used in daily life.
