Polycarbonate eID Card

Seven fused layers, a dual-interface chip and twenty security features on front and reverse.

How the IDMETRIX polycarbonate eID card is built: the layers it is laminated from, the printed design before and after personalization, the inks and what they do under UV, IR and NIR light, the antenna inside, and every security feature on both sides — each rated by the level of inspection needed to check it.

Card Construction

Seven Layers, One Monolithic Body

Around an opaque white inlay — the antenna core between two white cover sheets — the card is built outwards to both faces: a clear printed sheet, a laser-sensitive sheet and a clear overlay on each side. The printed sheets are transparent — the card only turns opaque once they are laminated onto the white inlay. No adhesive is used: the layers fuse into a single piece that cannot be split without destroying it.

Step 1 of 13 · The antenna core

Inlay core with antenna. The centre of the card: a copper-wire antenna and the chip module embedded in PC. The inlay is built as a separate product and fused into one opaque white sheet.

Fused, not glued

Delamination to swap the photo or data tears the printed and engraved layers apart.

Data inside the body

Laser engraving blackens the PC below the surface. It cannot be scratched off or overwritten.

Window in the inlay

The white inlay is cut out at the see-through window, so only clear PC remains there.

Inspection Levels

One Card, Four Levels of Inspection

Every feature is rated by the level of inspection needed to check it, so a glance at the counter, a simple tool and a lab each have their own checks.

1Level 1

Everyone, no tools

No equipment required to verify authenticity. Look, feel, tilt, hold against the light.

2Level 2

Simple device

A simple device is required — magnifier, UV lamp, IR viewer, NIR pen or document reader.

3Level 3

Forensic lab

Forensic equipment and specialist knowledge are required to verify authenticity.

4Level 4

Manufacturer only

Authenticity can only be verified by the manufacturer, using undisclosed reference data.

Print Design & Invisible Light

The Same Card Under Five Kinds of Light

The security printing as it leaves the press, the finished card, and what appears under ultraviolet, infrared and near-infrared light. The card body is made UV-dull, so under a 365 nm lamp only the intended inks light up.

eID card specimen, front, daylight

The finished card

Portrait, CLI and personal data engraved into the laser layer, the DOVID inside the card, over the portrait edge.

Relief you can feel

Tactile laser relief

The card number, raised by the laser foaming the polycarbonate under it, so it can be felt. Braille can be added the same way.

Debossed structure

A globe and waves of microtext pressed into the overlay by the laminating rollers or plates.

CLI lens field

Lenticular lenses over the laser image; the relief is the optical element.

Dual-Interface Antenna

One Chip, Two Ways to Talk to It

A single secure chip module is wired both to a gold contact plate and to a copper antenna embedded in the inlay. Terminals can read it by contact or wirelessly — the same applications and keys answer on both interfaces.

Front view

Coil & module under the OVI cover

Five turns of copper wire run around the card edge and end at the chip module, which sits beneath the optically variable emblem on the front.

Reverse view

Contact plate on the reverse

The module’s gold contacts come to the surface on the reverse. Antenna and plate share the same chip, so the card behaves identically in a slot or on a pad.

Contactless

ISO/IEC 14443 · 13.56 MHz

Border e-gates, mobile readers, smartphones via NFC.

Contact

ISO/IEC 7816

Card readers at desks, kiosks and for PIN-based e-signature.

Protected inside

Embedded, not printed

Coil and module are laminated between the cores — invisible, and destroyed by tampering.

Colours & Inks

Ten Inks on the Front, Six on the Reverse

Each colour is a separate spot ink, not a CMYK mix. Iris inks blend into each other without a dot screen; UV and IR inks add behaviour no office printer can reproduce. The optically variable ink is not among them: it is screen-printed onto the laminated card.

Swatches are screen approximations of the spot inks. Inks tagged UV are visible colours with an added UV pigment; they glow under a 365 nm lamp.

Security Features

Twenty Features on Front and Reverse

Twelve printed and embedded features protect the front and eight the reverse. They are layered so that every level of inspection has its own checks, and no single forgery technique can reproduce them all.

Features 1–12 · Front

eID card specimen, front, with feature markers

Point at a number to find the feature.

  1. 1

    Anti-Stokes feature

    NIR laser 980 nmLevel 2

    A covert up-converting pigment in the red “ID” logo turns invisible near-infrared light into visible green — the reverse of normal fluorescence. Invisible in daylight and under UV.

    Why it matters. Up-converting pigments are controlled security materials; a scan, print or copy stays dark under the laser.

  2. 2

    IR drop-out

    IR 850–950 nmLevel 2

    The design is printed in IR-transparent inks, so under infrared almost all colour vanishes. Only the title “IDENTITY CARD” in IR-absorbing black and the laser-engraved data stay dark.

    Why it matters. CMYK and inkjet copies react to IR uniformly. Document readers use the IR image for automatic checks.

  3. 3

    Tactile laser relief

    Touch · oblique lightLevel 1

    At personalization the laser foams the polycarbonate under the card number: the material swells and the digits stand up from the face, so they can be felt with a fingertip as well as read. Braille for blind holders can be added the same way.

    Why it matters. Relief cannot be printed, and it is formed inside the card body: skimming or relaminating the surface to change the number flattens it.

  4. 4

    Microprinted letter field

    Magnifier 8–10×Level 2

    Rows of red capitals scattered over a grid on the right of the face. Seen from arm’s length they read as a texture; under a loupe they are the letters of UTOPIA, set with irregular gaps.

    Why it matters. The fine letters and their spacing blur into shapes in any scan or copy, and are hard to reset by hand.

  5. 5

    Optically variable ink (OVI)

    TiltLevel 1

    The globe emblem is screen-printed onto the laminated card in ink with interference flakes that shift from magenta to green with the viewing angle.

    Why it matters. Scanners and printers capture one angle, so a copy shows one static colour. OVI pigment is sold only to security printers.

  6. 6

    Changeable laser image (CLI)

    Tilt left–rightLevel 1

    Laser engraving under lenticular lenses in the card surface: one angle shows the holder’s portrait, the other the year of birth.

    Why it matters. Personal data is written inside the card body at personalization. It needs a lenticular card and special laser optics, and cannot be altered without destroying the lenses.

  7. 7

    Guilloches with variable line width

    MagnifierLevel 2

    Contour-like lines that swell and thin, running around the title and the right edge of the face, printed so that colours blend without a dot screen.

    Why it matters. Continuous fine lines and seamless colour transitions break into CMYK dots in any reproduction.

  8. 8

    Fluorescent blue ink

    UV 365 nmLevel 2

    The octagon lattice on the right is printed in visible light blue with an added UV pigment that glows bright blue.

    Why it matters. The card body is UV-dull, so only intended elements light up. Common plastics and papers glow all over or not at all.

  9. 9

    Positive microtext

    Magnifier 8–10×Level 2

    The dotted blue line that waves across the face is a line of microtext about 0.25 mm high.

    Why it matters. Below copier resolution: a reproduction turns it into a dotted or solid line.

  10. 10

    Hot-stamped DOVID

    TiltLevel 1

    A diffractive optically variable image: a transparent holographic foil hot-stamped onto the laser-sensitive PC layer and laminated under the clear overlay, overlapping the portrait.

    Why it matters. Its moving, colour-changing effects cannot be printed. Covering the photo edge blocks photo substitution.

  11. 11

    Fluorescent red & yellow inks

    UV 365 nmLevel 2

    The red guilloche arcs and the pale yellow emblem behind the personal data carry UV pigments: under UV the arcs glow red and the emblem yellow-green.

    Why it matters. Two UV colours in register with the visible print are hard to match; a single-ink copy cannot reproduce both.

  12. 12

    See-through window

    Transmitted lightLevel 1

    A clear area in the opaque polycarbonate body, fused during lamination, with the logo printed inside it and visible from both sides.

    Why it matters. Cannot be imitated on an opaque substrate; splitting the layers destroys it.

Features 13–20 · Reverse

Point at a number to find the feature.

  1. 13

    Fluorescent red ink

    UV 365 nmLevel 2

    The red line bands at the top and right of the reverse glow red under UV.

    Why it matters. Only intended elements light up on the UV-dull body; ordinary inks and toners do not fluoresce in controlled colours.

  2. 14

    Radial guilloche fan

    MagnifierLevel 1

    A fan of fine lines radiating from the centre of the reverse, whose width swells and thins in steps.

    Why it matters. Seamless line-width modulation breaks into dots in any scan or reprint.

  3. 15

    See-through window

    Transmitted lightLevel 1

    The clear window from the front seen from the reverse — the logo printed inside it shows through, mirrored.

    Why it matters. Cannot be imitated on an opaque substrate; splitting the layers destroys it.

  4. 16

    Contour-line pattern

    MagnifierLevel 2

    Fine contour lines, like a relief map, run under the data at the top of the reverse; each line keeps its course without breaks.

    Why it matters. Scans break the hair-thin lines into dots and steps; they cannot be rebuilt by hand.

  5. 17

    Machine readable zone (MRZ)

    Reader · IRLevel 1–2

    Three lines of 30 OCR-B characters (ICAO 9303, TD1) with check digits, laser-engraved and readable in IR.

    Why it matters. Readers verify check digits and compare the MRZ with the chip and printed data.

  6. 18

    Irregular complex background

    MagnifierLevel 1

    A non-repeating crackle network in iris print fills the lower half of the reverse; no two cells are alike.

    Why it matters. It cannot be tiled or rebuilt from a scan; any copy loses line continuity.

  7. 19

    Fluorescent blue cell network

    UV 365 nmLevel 2

    The blue cell network on the left of the reverse is printed with a UV pigment and glows blue under UV.

    Why it matters. A second UV colour in its own register; a single-ink copy cannot match both.

  8. 20

    QR code

    Smartphone · readerLevel 2

    Laser-engraved 2D code that can carry a digitally signed extract of the holder data.

    Why it matters. Offline check: the signed data must match what is printed and stored in the chip.
