Product Description
13.56 MHz key fob for ISO14443A-based access control installs — programmable per-chip, ABS body, keyring form factor.
Spec relevant on site: it operates at 13.56 MHz and targets ISO14443A NFC systems, which covers the great majority of current-generation door controllers and NFC-capable readers rather than legacy 125 kHz EM/HID proximity gear. Confirm reader protocol before ordering in bulk for a mixed-generation estate.
Key specs
- Frequency: 13.56 MHz
- Protocol: ISO14443A (NFC)
- Programming: programmable RFID tag; writable memory depends on the chip fitted
- Housing: ABS plastic, water-resistant, rated for indoor and outdoor use
- Form factor: compact keychain fob
- Also listed as: GR-ACM-KEYFOB-13.56MHZ-LN
Deployment notes
Each fob transmits an ID string to the reader on presentation; the controller or access software then grants or denies access against the programmed permission set. That means enrolment happens in your software or door controller, not on the fob itself — plan admin time accordingly for large user counts.
Typical install contexts: office and residential door access, staff attendance logging, parking access and general security access control where a contactless credential is preferred over a card. The waterproof ABS shell suits external readers on gates, barriers and outbuilding doors as well as internal door sets.
Stock the fob against controllers or readers already confirmed as ISO14443A/13.56 MHz — it is not described as compatible with 125 kHz proximity systems.

Frequently Asked Questions
What frequency and protocol does this fob use?
It operates at 13.56 MHz and is designed for compatibility with ISO14443A RFID/NFC systems.
Can it be programmed with custom data?
Yes, it is a programmable RFID tag; the writable memory available depends on the specific chip fitted.
Is it suitable for outdoor readers, e.g. on a gate?
The housing is water-resistant ABS plastic, described as suitable for both indoor and outdoor access control use.
Will it work with older 125 kHz proximity readers?
The source specification lists ISO14443A/13.56 MHz compatibility only, so it is not confirmed to work with 125 kHz proximity systems.
