DESFire Tag
A contactless tag or key fob built on NXP MIFARE DESFire, offering AES cryptography and a multi-application file structure for access control, transit and cashless systems.
RFID key fobs and key tags for access-control integrators and distributors. Compare housings and materials with 125 kHz, MIFARE Classic, DESFire and other chip options, including proximity fobs. Start from the installed reader and credential format when specifying replacements, then test samples before ordering in volume.

Selection & ordering guide
For an integrator or distributor, a replacement fob needs to be identified precisely enough to reorder. Record the credential specification alongside the housing, colour and numbering; a similar-looking fob is not a sample approval.
Include the reader brand and model, the chip used in the current fob and any credential-format requirements. If you do not have the chip details, request a compatibility review before deciding on a replacement.
Compare the listed ABS, leather and other formats for the customer’s key ring, branding and daily handling. State any exposure to water, cleaning agents or outdoor use so the proposed construction can be checked.
Agree visible serial numbers, colours by site or user group, encoding responsibility and how the access-system operator will enrol new credentials. Keep an approved sample and specification for later batches.
Include what you know. If the chip or product is undecided, describe the application and current equipment so we can review the options with you.
