We accept bank wire transfer (T/T), PayPal, and letters of credit for large orders. Standard terms are 30% deposit with balance before shipment. For established partners, we offer NET 30 payment terms.

Most EV charging credentials use 13.56 MHz contactless technology. Available options include UID-oriented credentials, legacy sector-memory credentials, AES-authenticated applications and NFC-enabled chips, plus selected 125 kHz or dual-frequency constructions for defined legacy requirements.

OCPP compliance alone does not determine card compatibility. The card does not speak OCPP: the reader obtains an identifier or authenticates a supported application, and the charge point sends the resulting token to its backend. We confirm the reader technology, identifier format and backend route, then validate finished samples on representative stations.

Common options include UID-oriented 13.56 MHz credentials, legacy sector-memory credentials, AES-authenticated multi-application credentials and NFC-enabled chips. The choice depends on reader support, identifier format, memory, provisioning and whether the system authenticates a protected application or reads only a public UID.

Service life depends on the card-body material, inlay, print method, coating, handling and exposure. We recommend a construction for the intended environment and confirm the applicable physical and RF tests in the approved sample specification rather than applying one lifetime claim to every card type.

RFID and ISO 15118 Plug and Charge are separate authorization paths that may coexist. RFID normally identifies a token or account through the station reader; Plug and Charge uses vehicle and charging-system certificates. Support depends on the station, vehicle, backend and operator configuration.

An AES-authenticated credential is useful when compatible readers can authenticate a protected application and the operator has secure key generation, diversification, provisioning and custody. If chargers read only a public UID, selecting a cryptographic chip does not by itself provide cryptographic card authentication; backend fraud controls remain essential.

13.56 MHz High Frequency (HF) cards comply with ISO 14443A/B and offer faster data transfer (up to 848 kbit/s), encryption capabilities, and anti-collision for reading multiple cards. This is the global standard for EV charging stations, payment systems, and modern access control. 125 kHz Low Frequency (LF) cards like EM4100 and 125 kHz proximity are read-only, have no encryption, and slower data rates — they're used in legacy access control systems. We manufacture both frequencies and can produce dual-frequency cards embedding both LF and HF chips in a single card body for backward compatibility.

The reader obtains the configured identifier or authenticates a supported protected application. The charge point then sends the token to its management system through the applicable OCPP authorization flow. The backend accepts or rejects the token according to its local, eMSP or roaming records. The card itself does not communicate with OCPP.

Our cards use precision-etched or wire-wound copper antennas tuned to the operating frequency. For 13.56 MHz cards, the antenna consists of 3-5 turns of copper wire or etched aluminum coil embedded between the card's lamination layers, connected to the RFID chip via a bonding process. The antenna design is optimized for the ISO 14443 communication range of up to 10 cm. For wooden cards, we use a precision-milled cavity in the wood substrate to embed the antenna and chip module, ensuring consistent read performance through the natural material. Each card undergoes RF testing to verify resonant frequency and read range meet specification.

ISO/IEC 7810 covers card dimensions and ISO/IEC 14443 covers short-range contactless communication at 13.56 MHz. OCPP links the charge point and its management system; OCPI and OICP support roaming-system exchanges. None of these protocols is a universal card-compatibility certificate, so the finished credential is tested with the intended reader, identifier format and backend flow.

A dual-frequency card contains two separate chip-and-antenna systems, commonly 125 kHz and 13.56 MHz. It can support a defined mix of legacy and newer readers, but available constructions are limited by antenna geometry and chip selection. Finished samples must be tested on representative readers; dual frequency does not guarantee estate-wide compatibility.

Cloning resistance is an end-to-end property. A protected AES application can support mutual authentication and diversified per-card keys, but those controls help only when the reader verifies that application and keys are securely managed. UID-only systems should treat the identifier as copyable and rely on revocation, anomaly detection, limits and account alerts.

ISO/IEC 14443 credentials are designed for short-range proximity operation. Actual read distance depends on the reader field, antenna tuning, card construction, nearby materials and installation. We validate the finished construction on the intended reader rather than promising a universal range.

Personalization may include recording a UID mapping, writing an agreed identifier, configuring protected files, loading application keys or formatting an NDEF record. The exact process depends on the selected chip and authorization design. Key material, access conditions, data format, audit trail and sample acceptance must be agreed before production.

Our manufacturing follows a 4-stage quality control process. Stage 1 — Incoming Inspection: all raw materials (PVC sheets, chip modules, antenna coils, wood veneers) are tested against specifications. Stage 2 — In-Process Checks: print registration, lamination bonding, chip embedding alignment, and antenna connection integrity are verified at each production step. Stage 3 — Final Inspection: every card is tested for RF performance (resonant frequency, read range, data integrity), visual quality (print alignment, surface defects), and dimensional accuracy (ISO 7810 compliance). Stage 4 — AQL Batch Sampling: statistical quality inspection of finished batches using Acceptable Quality Level protocols before packing and shipment.

Recycled content depends on the approved construction. The quotation and material declaration should identify the recycled percentage, whether it is post-consumer or post-industrial, and which card layers it covers. Durability and read performance are checked on the finished sample rather than assumed to be identical to another construction.

Yes. Our wooden RFID cards are manufactured from FSC-certified cherry wood or bamboo, ensuring the wood comes from responsibly managed forests. Each batch includes FSC chain-of-custody documentation for your sustainability reporting.

Yes. Our PPH Bio cards are crafted from renewable wood fiber and designed to naturally decompose at end of life under composting conditions. During their service life, they remain durable, moisture-resistant, and fully functional. This eliminates the long-term plastic waste associated with traditional PVC cards.

Environmental impact depends on the final construction, supplier records, transport and order scope. We can provide relevant material and sourcing documentation for recycled PVC, eligible FSC wood and bio-based options. Validate any environmental claim against the evidence available for the exact quoted product.

Yes. We offer full-color offset and digital printing on both sides of PVC and bio cards. Options include network logos, custom color schemes, QR codes, serial numbers, and variable data printing. Wooden cards support laser engraving and single-color print for branding.

Yes. We offer chip programming and encoding services including UID assignment, sector key configuration, application data writing, and NDEF formatting for NFC cards. We can program cards to your charging network's specifications for plug-and-play deployment.

Beyond standard CR80 cards, we manufacture RFID key fobs, wristbands, windshield tags (for fleet vehicles), and custom shapes. All form factors support the same RFID chip options and can be branded to your network identity.

Yes. We can define the identifier file, numbering and provisioning handoff for the operator's existing technical and commercial connections. The operator or platform owner remains responsible for activating tokens, roaming routes and authorization rules; the finished card is sample-tested before production.
