Product overview / 01

RFID keyfobs for everyday charging access

An EV charging RFID keyfob carries the same kind of contactless credential as a card in a smaller form designed for a keyring. It is useful when drivers want the charging token attached to the vehicle key, when a fleet issues compact credentials, or when a programme offers card and fob choices under the same account model.

FSC wood gives a natural engraved finish, moulded ABS prioritises impact resistance, domed epoxy protects full-colour artwork, and transparent crystal acrylic makes the embedded antenna part of the visual design. Each construction changes thickness, edge behaviour and antenna geometry, so finished samples must be tested at the actual reader positions used across the charging estate.

Reader position

Check that the keyfob can be placed flat and close enough to readers recessed behind charger housings.

Construction choice

Select wood, ABS, domed epoxy or crystal acrylic according to branding, impact, scratch and presentation requirements.

Identifier workflow

Confirm the same UID or token format used for cards can be imported and managed for fobs.

Visible identification

Decide how support teams and drivers will distinguish, assign and replace small credentials.

Features and options / 02

What can be specified.

The body construction should be selected deliberately: each option creates a different balance of appearance, branding method, wear profile and reader geometry.

FSC wood

A slim laminated wooden body supports laser engraving and visible natural grain. Specify species, finish, edge sealing and expected moisture exposure.

Moulded ABS

An injection-moulded shell is the practical choice for high-volume daily handling, with pad print, laser marking and multiple mould colours available.

Domed epoxy

A clear resin dome protects a full-colour printed insert and creates a glossy, tactile branded surface. Check yellowing, scratching and edge adhesion in the approved sample.

Crystal acrylic

Transparent acrylic can reveal a fine embedded antenna and internal artwork for a premium technical look. The antenna remains functional, not merely decorative.

Reader-matched electronics

Each construction can use a compatible 13.56 MHz chip and antenna geometry, subject to available body space and finished-sample validation.

UID and visible references

Electronic identifiers, serials or QR references can be paired in a delivery file for activation, support and controlled replacement.

Technical fit / 03

Small format, full credential workflow

The keyfob is convenient for the driver, but its inlay, identifier and replacement controls need the same care as a card.

Read range is reader-dependent

A smaller antenna may behave differently on metal-fronted or deeply recessed readers. Do not approve from a desktop reader test alone.

The fob does not store charging history by default

Session and billing records normally live in the charging platform; the keyfob presents the credential used to find that account.

Security follows the reader capability

AES-authenticated 13.56 MHz credential features help only when the charging reader and authorization design actually use secure application authentication.

Visible numbering helps support

A human-readable reference allows helpdesk teams to suspend or replace a credential without asking a driver to read its electronic UID.

Test the attachment point

Keyring holes, inserts and body thickness should be evaluated for daily mechanical wear as part of sample approval.

Transparent does not mean unprotected

In a crystal-acrylic design, the visible antenna and chip should be fully encapsulated inside the body rather than exposed on the surface.

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.

Does an EV charging keyfob work like an RFID card?

Usually yes at the account level: the reader captures the credential identifier and the charging platform decides whether to authorize. The smaller antenna means the physical tap position should be tested separately.

Can the same account have both a card and a keyfob?

That is normally possible when the charging platform allows multiple tokens to be assigned to one customer or vehicle. The platform owner defines the account relationship; we supply the unique credential data needed for import.

Which chip is best for a charging keyfob?

Use the chip already supported by the target reader and backend. Confirm frequency, protocol, UID length and whether the system uses a simple identifier or secure application data.

Which RFID keyfob material should I choose?

Choose FSC wood for natural engraved presentation, moulded ABS for robust everyday use, domed epoxy for protected full-colour branding, or crystal acrylic when a transparent premium design and visible embedded antenna support the programme identity. Validate the selected construction on the real charger reader.

Are keyfobs weather resistant?

The selected body and finish can be designed for normal keyring and outdoor use, but no construction is immune to every combination of water, heat, chemicals and impact. State the service environment and test finished samples.

Can each keyfob be numbered?

Yes. A visible serial, QR code or account reference can be printed or engraved and paired with the electronic identifier in a delivery file.

What is required to test a keyfob?

Provide representative charger readers or models and the backend identifier rules. Test the finished fob at real reader positions and complete a live authorization before volume production.

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.
