We match the credential to your system

Smart card manufacturer for integrators. Send the reader or lock model: we confirm the chip in writing, then encode and test every chip.

What decides compatibility

Three variables decide whether a card reads. Here they are in one place.

The frequency

125 kHz, 13.56 MHz or UHF. This one we can confirm from the reader or lock model alone, and it is the fastest of the three for us to settle.

The chip family

MIFARE Classic EV1 1K and DESFire EV3 share a frequency and are not substitutes. The reader decides, not the age of the chip, and the model usually tells us.

How the system was configured

This is the one that sometimes needs a card in a door rather than a document. Where that is the case we say so, instead of quoting it as settled.

What we send before you commit

A written chip confirmation, and a sample where the sheet is not enough.

Reorders

Specification on file

The approved specification kept on file for every reorder that follows.

What we hold as standard

Every chip is read-tested, 100%. Not listed? Send the part number.

13.56 MHz and NFC

MIFARE Classic EV1 1K and 4K, MIFARE Ultralight EV1, MIFARE DESFire EV2 and EV3, NTAG213, NTAG215 and NTAG216, and ICODE SLIX, in PVC and wood. Read and write depends on chip features and permissions.

125 kHz

EM4200 (read only) and T5577 (read and write), in cards and key fobs. This is what the legacy proximity readers, the door intercoms and the older access systems still in service are reading.

UHF, 860 to 960 MHz

Impinj Monza and Alien H3, in cards and wristbands. Not available in key fobs. At UHF the credential has to be a card or a wristband, read and written in enabled memory areas.

Where the material limits the chip

Wood takes contactless only. A contact module cannot be milled into it reliably, and a wood card is 1.20 to 1.30 mm against 0.76 mm in PVC, so the slot is what to check rather than the read.

Encoding, and who holds the keys

Encoded at the plant where the chip allows. What can be written depends on the keys.

Open or unencrypted systems

We encode to your specification and ship the credentials programmed. Sequential or non sequential numbering, and a UID list delivered with the order so your system has the population before the box arrives.

Encrypted systems

Where the keys belong to the system owner, we supply the correct chip and the credential itself is written by whoever controls those keys. That is usually you. We will not pretend otherwise to win a line on a quote.

We tell you which one you are in

Before you order, not after. It changes what you have to do on site, and finding out at delivery is the expensive way to learn it.

Systems we encode for

Send the system and its version. An upgrade can change the chip a site needs.

What we confirm

Frequency and chip family, from the reader or lock model, or from the credential in service today. Post us a card and we verify it here.

Where the limits are

We supply the correct chip on encrypted systems. Where the keys belong to the system owner, the credential is written by whoever holds them, which is usually you.

What comes back

A written quote the same working day. Ask for a free sample in the chip you specify, and test it on the installed base.

Lock encoding depends on the chip and on each system's technical requirements, keys and authorisation. All trademarks are the property of their respective owners. No affiliation or endorsement is implied.

How an order works

Four steps, the same for every order.

01

You send the job

Quantity, format and the reader or lock model, with firmware where known. Artwork can come later.

02

A written quote the same working day

The chip confirmed against your system and a price against that specification.

03

A free sample to test

Ask for a free sample and test it where it will be used.

04

Production and reorders

Standard production is 12 calendar days. The specification stays on file, so a reorder matches the first run.

One chip, three form factors

Card, fob or wristband on the same chip, so the reader treats all three alike.

Cards

CR80 as standard, in PVC, recycled PVC or wood, and cut to your outline where the credential has to do something a rectangle cannot.

Four ABS RFID key fobs in white, navy, grey and green, each on a split ring

Key fobs

Moulded ABS, 31 to 56 mm across twelve shapes, at 125 kHz and 13.56 MHz. The material that survives a keyring, which is the whole job.

Wristbands

Silicone, fabric, vinyl and Tyvek, chosen by how long the band stays on the wrist and whether it has to be tamper evident.

Questions we hear the most

Can you encode to my system before shipping?

Yes, on open or unencrypted systems, with a UID list delivered with the order and every chip read-tested before shipping. Where the keys belong to the system owner, we supply the correct chip and the credential is written by whoever holds those keys.

We only have the card, not the documentation. Is that enough?

Often. Send a physical card together with the reader or lock model, and the frequency and chip family are identified at the plant by reading the card itself. The chip and encoding are then confirmed in writing before production.

Can you supply UHF fobs?

No. Fobs are 125 kHz and 13.56 MHz only. At UHF the credential has to be a card or a wristband, and we make both, so the answer is a different form factor rather than a different supplier.

Can one order cover cards, fobs and wristbands?

Yes, with the same chip in all three, encoded the same way, so the reader does not know the difference. Quoted, produced and delivered together, and the specification stays on file so a reorder of any one of them matches.

Will a reorder read the same as the batch already installed?

Yes. The chip, the artwork, the colour references and the finish stay on file and the reorder is produced against them, so you are not re-testing a specification the site already accepted.

The client is changing lock system. Can you match both for a while?

Tell us both models. Where a single chip covers both we will say so, and where it does not we will say that instead, which is the more useful answer during a migration.

Do you make metal cards?

No. PVC, recycled PVC, wood and bamboo in cards, moulded ABS in fobs. If the specification calls for metal we are not the right supplier for it and would rather say so early.

Can a card carry a chip and a magnetic stripe?

On PVC, yes, on the same card. Send the encoder or the system that writes the stripe so the coercivity is matched rather than assumed. Wood cannot take a stripe at all.
