Product overview / 01

A custom credential starts with the system brief

Custom EV charging credentials are built when a standard CR80 card and simple UID handoff do not cover the programme. The requirement may involve a compact form factor, dual-frequency operation, protected chip applications, unusual personalization, direct fulfilment or a defined interface to an existing credential database.

The most efficient starting point is an existing card, reader model or authorization-flow description. From that evidence we can separate mandatory electronic requirements from choices such as material, shape, artwork and packaging, then build a sample that can be tested before production tooling or volume is committed.

System boundary

Identify the readers, charging stations, backend, access controllers and other systems the credential must serve.

Data and security

Define UID, token, memory, key ownership, application data and file-handoff requirements.

Physical workflow

Explain how drivers carry, present, replace and return the credential in daily operation.

Rollout model

Provide pilot quantity, annual forecast, destinations, packing and any direct-to-driver fulfilment requirement.

Features and options / 02

What can be specified.

Customisation can cover the physical token, the electronic inlay and the operational delivery process—not only the printed artwork.

Custom form factors

Cards, compact tags, keyfobs and other shapes can be developed around reader position and handling needs.

HF, LF or combined inlays

Single- or dual-frequency configurations can bridge EV charging and an approved legacy access requirement.

Secure application provisioning

AES-authenticated 13.56 MHz credential applications, file structures and keys can be loaded under an agreed, controlled provisioning process.

Identifier engineering

UID representation, prefixes, visible numbering and backend mapping can be structured for the target platform.

Programme presentation

Materials, print, engraving, packaging and mailer components can be developed as one coherent credential pack.

Pilot and repeat production

Prototype samples, approval records and controlled master data reduce risk when the programme scales or reorders.

Technical fit / 03

Turn unknowns into testable decisions

Custom work is successful when every requirement has an owner, an approval method and an output that can be repeated.

Start from physical evidence where possible

Reading an existing credential or testing the target hardware is more reliable than choosing a chip from a generic list.

Separate public identifiers from protected data

A UID-only flow, an NDEF record and a secure AES-authenticated 13.56 MHz credential application require different provisioning and reader behaviour.

Dual frequency needs layout validation

Two antennas in one body affect space, coupling and read performance; both target systems must be tested on finished samples.

Key handling must be agreed before production

Ownership, transfer, diversification, access rights and deletion rules should be documented before secure personalization begins.

The pilot should mirror production

Use the intended material, inlay, encoding, artwork and data file so approval proves the complete workflow rather than one isolated component.

Separate the physical card from its credential data.

Request Samples

Physical

Materials: Recycled PVC, wood-based, bio-fibre and programme-specific constructions
Form Factors: CR80 cards, keyfobs, compact tags and approved custom shapes

Technical

RFID Options: 13.56 MHz HF, selected 125 kHz LF or dual-frequency after reader validation
Branding: Print, engraving, variable data and custom packaging
Prototypes: Production-representative samples required for new constructions

Ordering

Support: Specification, data-format review and sample test planning
MOQ: Defined by form factor, material, chip and tooling
Lead Time: Confirmed after the technical brief and prototype scope

Production route / 05

Approve the complete workflow before volume.

The sample should prove construction, print, electronic behavior and data handling together. That approved reference then controls production and reorders.

Frequently asked / 06

Questions buyers ask before ordering.

Answers are based on the physical credential and production scope. Your charging platform remains responsible for account, tariff and authorization rules.

What makes an EV charging RFID project custom?

Any requirement beyond a standard card with standard printing can make it custom: a different shape, dual frequency, secure applications, unusual data structures, special materials, packaging or an integrated fulfilment process.

Can you copy our existing charging credential?

We can inspect an existing credential and reproduce approved physical and electronic requirements where you own or are authorized to use them. Protected keys or proprietary applications require documented access and cooperation from the system owner.

Can one credential work for charging and building access?

Potentially. The two systems may use the same technology, separate applications on one secure chip, or different frequencies. Both reader estates and the security owners must be included in the specification and test plan.

How are cryptographic keys handled?

The process is defined per project and should cover key ownership, secure transfer, diversification, authorized personnel, provisioning evidence and deletion. Do not send production keys through ordinary email.

Do custom projects require prototypes?

Yes for any new construction, antenna, chip configuration, artwork method or data workflow. A production-representative sample is the approval reference for functionality and appearance.

What should we send for an initial review?

Send the current card or tag, reader and platform details, required functions, estimated quantity, launch date, artwork expectations and any known chip, UID or security requirements.

Build the brief with evidence.

Use the technical guide, programme examples and glossary to align procurement, engineering and operations before requesting samples.

Included with every order

Every order ships with a data contract and acceptance pack.

Before production starts, we fix the identifier format with your backend team: byte length, representation, byte order, leading-zero policy. The order then ships with a machine-readable data contract and acceptance vectors your engineers can test against before the first card arrives.
