| Card format | ISO/IEC 7810 ID-1 format | Usually available | Usually available | Usually available | Request confirmation that the finished card is 85.60 × 53.98 mm. |
| Standard card thickness | Approximately 0.76 mm for a standard payment-card-style format | Common stock option | Custom thickness possible | Broadest specification range | Check tolerance, printer clearance, and reader performance. |
| Contactless technology | High-frequency contactless technology compliant with the required system | Limited configurations | Several standard configurations | Multiple chip and inlay configurations | Do not approve from appearance alone; validate the chip, antenna, and encoding profile. |
| Typical operating frequency | 13.56 MHz for many modern contactless smart-card platforms | Typically one frequency option | Commonly supports 13.56 MHz options | Can source multiple frequency families | Match the frequency and protocol specified by the hotel access-control deployment. |
| Material options | PVC, PET/PETG, paper-based composite, or biodegradable polymer subject to performance testing | PVC is most common | PVC, PET, and selected recycled-content options | Widest material and finish selection | Compare durability, recyclability, moisture resistance, and disposal requirements. |
| Printing capability | Offset, digital, or dye-sublimation-compatible surface | Standard one- or two-sided printing | Full-color customized printing | Advanced finishes, variable data, and security printing | Request color proofing, print-registration tolerance, and surface-finish samples. |
| Encoding and personalization | Encoding must follow the access-control provider’s approved data structure | Usually blank cards or basic numbering | Optional numbering and basic encoding | Advanced encoding, UID handling, and variable data services may be available | Use a written encoding specification and conduct live reader tests before mass production. |
| Minimum order quantity | Varies by stock, customization, chip type, and printing method | Lowest for standard stock items | Moderate for customized orders | Often higher for fully customized production | Compare total landed cost at the actual order quantity, not only the unit price. |
| Sample and approval process | Physical sample plus functional reader test | Fast sample availability | Printed pre-production sample commonly available | Formal proof, prototype, and quality approval process | Require written approval against artwork, dimensions, chip data, and test results. |
| Quality-control documents | Material specification, inspection report, and batch traceability | Basic inspection documentation | Batch inspection and production records | More structured quality-management documentation | Ask for measurable acceptance criteria rather than generic quality claims. |
| Lead-time profile | Stock orders are generally faster than custom production | Fastest for standard cards | Balanced production and delivery time | Longer planning cycle for complex customization | Request separate timelines for sampling, production, inspection, and shipping. |
| Compliance and sustainability | Applicable product, packaging, chemical, and environmental requirements | Basic compliance support | More documentation for export shipments | Broader documentation and material declarations | Verify destination-country requirements and request current declarations for materials and packaging. |
| Best fit for | The right supplier depends on volume, customization, compatibility, and delivery risk | Urgent replenishment and small standard orders | Regional hotel groups and medium-volume programs | Large-scale, multi-country, or highly customized programs | Select using a weighted scorecard covering compatibility, quality, total cost, lead time, and support. |
