Already know the application? Review hotel key cards, custom printed RFID cards or NFC business cards, or go to the quote checklist.
Choose the RFID card type by its job
An RFID card combines a chip and antenna with a card body. Its appearance does not identify the chip or tell you whether the intended system can issue and use it. Separate the application, the electronic specification and the printed design when comparing cards.
| Application | Product route | Information to establish first |
|---|---|---|
| Replacement or new cards for a hotel | Hotel key cards | Lock model, issuing software, encoder and current credential specification |
| Branded access badges, membership or event credentials | Custom printed RFID cards | Reader / issuing system, artwork versions, variable data and who will encode |
| Team profiles or contact sharing by phone | NFC business cards | Shared or individual links, profile ownership, printed names / QR codes and target phones |
For an existing property, use the hotel key-card compatibility checklist. For artwork-led orders, use the custom printed card specifications. For team sharing, use the NFC business-card planning page. These routes organize the purchase; they do not establish compatibility without the project details and sample checks.
If your team adds names or photos when issuing cards, also review RFID / NFC card options for printable blanks and identify the printer, consumables and encoder. A branded hotel card can involve both printing and issuing requirements, so include both in the same brief.
Match the existing reader and issuing system before choosing a chip
Record the exact lock or reader model, issuing software and encoder, then ask the system provider which credential specification it supports. Use an existing card's documented part number if available; a logo, card colour or broad chip-family name is not a complete specification.
- Reader and application: identify the equipment and the operation the card must complete, such as issuing a hotel stay, checking membership or opening a team profile.
- Credential: record the frequency, exact chip or approved part reference, data format and any enrolment requirements. Mark unknown details for confirmation.
- Issuing responsibility: name who configures, encodes and enrols the cards, and who will run the sample test. An existing system may require its own approved issuing process.
- Mixed installations: list each different reader or issuing setup separately. Do not assume a sample accepted at one location covers another configuration.
For example, NXP specifies NTAG213/215/216 as NFC Forum Type 2 and ISO/IEC 14443 Type A chips. A chip specification is one part of the selection; the intended application must also support the proposed card and record. Use the RFID frequency comparison and chip-family comparison to understand the terminology, then confirm the actual part with the system provider.
For NFC sharing, record the intended phones and the action after a tap. Agree who owns and maintains the profile, website or redirect service, including any ongoing charges. Use the NFC phone-test checklist; a card order alone does not specify a hosted profile service.
Plan printing, encoding and issuing as separate tasks
Printing puts the artwork, name, number or QR code on the card. Encoding writes the agreed chip data. Issuing connects the card to the intended application where that system requires it. Assign each task to the factory, your team or the system provider before approving the order.
| Decision | Record in the brief |
|---|---|
| Fixed and variable artwork | Front/back design versions, quantity per design, names, numbers, QR codes and reserved areas for later printing |
| Card body and finish | Dimensions, thickness, material, surface finish and any printer or card-holder constraints |
| Chip data and mapping | Example field names, shared or individual records, encoding responsibility and the relation to printed identifiers |
| Delivery and issuing order | Packing groups, record order and how reprints or replacements will be reconciled |
Use the RFID card printing and data-mapping guide for artwork preparation and printable-card checks. Keep printed identifiers, QR content and chip records in separate fields; do not assume a printed number can replace the chip UID. Initial examples can use fictional records. Live cardholder data and access keys are not needed in the quote form.
Choose the material and finish alongside the actual use and printing process. Ask for the proposed construction, then check its appearance, handling and operation on the sample. The card-material comparison helps organize the options; material names alone do not establish a service life or environmental certification.
Approve the finished card and its intended workflow
Agree what the sample needs to prove before requesting it. A visual proof and a working physical card answer different questions. Use the following as a planning checklist, not a record of completed tests:
- Record the sample specification. Identify the chip, card construction, artwork revision and intended test equipment or phones.
- Review the visible result. Check both sides, variable fields, finish, dimensions and any areas reserved for later printing.
- Complete the real operation. Issue and use a hotel or access credential in the intended setup; for an NFC sharing card, follow the tap through to the agreed online action.
- Reconcile printed and encoded data. Compare the sample with the agreed example records and check QR links separately where included.
- Record approval and open points. Agree the batch inspection scope, packing and replacement process. Reassess the sample plan if the chip, construction, artwork or system changes.
For hotel projects, the hotel key-card planning kit records the lock and issuing setup. For printed-card projects, the printed-card planning kit helps organize artwork, quantities and data mapping. Use a separate record for materially different configurations.
Compare quotes against the same approved specification
Request a written quote that identifies the chip and card body, quantity by design, printing, variable data, encoding, packing and delivery destination. Check which services and costs are included, which remain open, and what changes require a revised quote.
Confirm the minimum order for the selected configuration, sample availability and charges, proof and sample stages, production timing, shipping, payment and warranty terms. Your requested quantity and arrival date are planning inputs until confirmed. Use the MOQ and sample arrangements guide and ordering steps to prepare those questions.
Prepare an RFID card quote or sample brief
Start with the details you know; leave unknown items open for discussion:
- Application, target quantity and quantity per artwork version.
- Reader / lock, issuing software and encoder, or target phones for NFC sharing.
- Current credential or chip reference if known, and who will encode or issue the cards.
- Card dimensions, material, print sides, finish and variable fields.
- Shared or individual records, printed-to-encoded mapping, and ownership of any online destination.
- Sample purpose and intended test setup, delivery country and required arrival date.
Choose the matching inquiry to open an editable project checklist:
For another card application, describe your card project. The form accepts text; agree how to share artwork or data files when the team replies. You can request sample planning in the same inquiry without knowing every technical detail.

Frequently asked questions
How do I choose an RFID card for an existing system?
Identify the lock or reader model, issuing software, encoder and supported credential specification. Record the current card part reference if known, assign encoding and issuing responsibilities, then agree a sample test in the intended setup.
Can I choose a replacement card by frequency alone?
Frequency is only one selection detail. Confirm the exact chip or approved credential, data format and issuing requirements with the system provider. A matching appearance or broad chip-family name does not establish compatibility.
Should I order printed RFID cards or printable blanks?
Choose finished printing when the artwork and quantities are ready before production. If your team adds names or photos at issue time, identify the printer, consumables, card construction and encoder, then test a suitable blank or partly printed sample.
Does an NFC business-card order include an online profile service?
Confirm this separately in the quote. Specify the destination, who owns and maintains it, update access and any ongoing charges. Test the intended phone-to-page action on the sample.
What are the minimum order, sample cost and production time?
These must be confirmed for the selected configuration. Send the quantity by design, chip or system requirements, printing, encoding and delivery needs, then agree the commercial terms and approval stages in writing.
Can I request a quote before I know the chip?
Yes. Describe the application and provide the reader or issuing-system details you know. Mark the chip as unknown so it can be resolved before sample approval; do not guess a compatible part.
