Printed RFID Cards

What are custom printed RFID cards?

Custom printed RFID cards are contactless cards that carry your artwork, finish and per-card data around the chip your readers already use. They are ordered by system integrators, distributors and card issuers for access control, membership, hotel, loyalty, transport and campus schemes, where every card must look consistent and read reliably. The selection rule is simple: choose the chip for the reader first, then the material, then the print method and finish that suit your artwork and quantity.

Printing and chip choice are independent decisions. The same design can be printed on a 125 kHz card, a 13.56 MHz MIFARE or NTAG card or a UHF card (UHF card availability is confirmed in the quotation), as long as the chip matches the system that will read it. Custom printed NFC cards use the same process with an NTAG chip and can be encoded with your URL or vCard so a phone opens it on tap. The sections below explain print methods, finishes, variable data, artwork preparation, proofing and how printed numbers are matched to encoded chip data.

Which print method suits your card artwork?

Most printed RFID cards combine two or more processes, for example an offset CMYK background with a silkscreen spot colour and a digitally printed number. The method is chosen per project from the artwork, the colour requirement and the quantity.

Gloss, matte or frosted: which finish should you choose?

• Gloss gives the most saturated colour and the classic credit-card look. It shows fingerprints and fine scratches more readily.
• Matte reduces glare, feels smoother and hides handling marks; colours appear slightly softer than on gloss.
• Frosted has a fine satin texture and is often chosen for semi-transparent or premium cards.
• Combined finishes such as a matte card with UV spot gloss on the logo are possible; mark the spot areas on a separate artwork layer.

If the cards will be personalised later on a desktop card printer, tell us the printer model. The surface must be compatible with that printer, and a thermal-printable finish differs from an inkjet-receptive one such as the coated surface of an inkjet PVC card.

What variable data can be printed on each card?

Variable data turns a batch of identical cards into individually identifiable credentials. Supply the data as an Excel, CSV or XML file with one row per card and a column for each field.

• Sequential numbering: printed or laser-engraved on suitable materials, with the start number, prefix, font and position you specify.
• Barcodes: common symbologies such as Code 128, Code 39 or EAN-13, printed to your data. Place them on a light background with a quiet zone either side so scanners read them reliably.
• QR codes: static links or per-card codes. Size them for the scanning distance and check them on the proof with the phones or scanners you will use.
• Photo personalisation and names: per-card photos and text from your image files and data list, for staff, student or member ID cards.
• Magnetic stripe: HiCo or LoCo, encoded to your track data where the system still needs it.
• Signature and scratch-off panels: for signed membership cards or cards that hide an activation code.

How should artwork be prepared for RFID card printing?

Clean artwork avoids delays at proofing. Use the checklist below and ask for the card template for your chosen size, because bleed, safe margin and keep-out positions are confirmed on that template.

Keep-out zones matter more on RFID cards than on plain plastic cards. On contact and dual-interface cards the chip module sits in a milled cavity in the position defined by ISO/IEC 7816-2, so artwork in that area is removed and should not carry text or logo detail. On contactless cards, avoid placing photos, fine text or later desktop-printed fields directly over the embedded chip position shown on the template, because the chip can leave a slight surface bump that causes print voids. The antenna also runs inside the card, so a slot punch, hole or embossed text must be agreed before production so the inlay can be laid out clear of it. Do not add a punch to a finished card, because it can cut the antenna.

How are colours proofed and approved?

Each order starts with a digital proof showing layout, trim, keep-out zones, variable data positions and a sample of the numbering or barcode. The digital proof confirms content and placement, but a screen cannot show printed colour accurately.

• For brand-critical colours, give the Pantone reference and ask for a physical printed sample before production.
• Colours print differently on white PVC, natural wood, paper and PLA, so judge the colour on the material you are ordering.
• Metallic, pearlescent, foil and frosted effects should always be approved on a physical sample.
• Production starts only after written approval of the proof and, where agreed, the pre-production sample. Changes after approval normally require a new proof.

How do printed numbers match the encoded chip data?

Many systems need the visible card number and the chip data to agree, so staff can issue a card by its printed number and the reader recognises the same card. There are two common approaches, and both should be defined before production.

• Print what the chip already holds: the factory UID, or a number derived from it, is read from each card and printed on that card, often in a decimal or hexadecimal format your software expects.
• Encode what the card shows: a printed sequence, such as 000001 to 010000, is written into the chip memory, a MIFARE sector, an NDEF record or a UHF EPC to match each printed number. This needs a writable chip, such as a T5577 or EM4305 programmed with an EM4100-format ID, or writable HF or UHF memory. Read-only EM4200 IDs and factory UIDs cannot be changed, so for those chips the printed number is taken from the chip, and a reader that checks only the UID ignores any encoded sector.
• When we write to the chip, each card is read again once encoding is done and the order ships with a data report. Either way, numbered cards come with a list of every printed number beside its UID (TID or EPC on a UHF card), in the same file formats we accept for variable data, ready to import into your system.

Tell us the number format, byte order and any conversion your system applies to the UID, because the same chip ID can appear in different formats on different readers. The RFID encoding service explains UID reports, sector encoding, NDEF, keys and EPC data in detail, including how protected keys are handled.

Which chip should go inside a printed card?

Choose the chip from the reader, lock or software, not from the artwork. If you are replacing existing cards, send a working card or the reader model so the chip and data format can be matched.

For systems built around branded credential formats, specify the chip and data format your system provider accepts and confirm compatibility with that provider before ordering.

Which card materials can be printed?

Wooden cards are offered in cherry, sapele, bamboo, beech, birch, black walnut, basswood and maple. Each species takes laser engraving and UV printing differently, and wood grain varies from card to card, so approve the species and print on a sample. Wood cards are usually thicker than a 0.76 mm plastic card; thickness is confirmed per build, so check it against insertion locks, dispensers and encoder slots. Wooden cards can be encoded for hotel locking systems whose locks accept the chip; for lock-specific designs see hotel key cards.

How do samples, proof approval and lead time work?

Standard product samples are free, so you can check the chip, card body and finish against your readers before paying for custom work. Customised printed samples carry a setup fee, because they need their own artwork preparation and production setup. The fee and the sample quantity are confirmed in the quotation. A sample pack is a quick way to compare materials and finishes before you commit to artwork.

• Test a standard sample with your reader, lock or phone to confirm the chip and data format.
• Approve the digital proof for layout, keep-out zones and variable data positions.
• Approve a printed pre-production sample where colour, special finishes or encoding must be checked.
• Production and encoding start after written approval of the proof and any pre-production sample.

Standard products generally have a lead time of 2 to 3 weeks. Custom printed cards are scheduled from the date the proof and any pre-production sample are approved, and the production time is confirmed in the quotation. Large orders are scheduled individually. Transit time and freight are confirmed for your destination.

What should you send for a quotation?

• Chip type, or the reader, lock or software model, plus a working sample card if you are replacing existing cards.
• Quantity, card material, size and thickness.
• Artwork or a design brief, the print method or effect you have in mind and the finish.
• Variable data: numbering format, barcode or QR content, photos and names, with a sample data file.
• Encoding needs: UID report, sector data, NDEF record or EPC, and how the printed number must match the chip.
• Delivery country and target date.
