RFID Technology Identification and Compatibility Assessment
Every card, key fob or UHF tag is identified before any next step is proposed. We read the frequency band, the chip family and the physical format, then record what the credential is and how it is used.
The assessment is non-destructive and is carried out only for credentials linked to authorized access requirements. Where an encrypted enterprise system cannot be serviced, we say so plainly.
Diagnostic procedure: photograph the credential, identify the frequency band, confirm the chip architecture, then assess compatibility with the existing reader.
Identification steps
1. Record the card format, markings and physical condition.
2. Identify the operating frequency and chip family.
3. Test compatibility against the existing access point.
Frequency guide
Low-frequency, high-frequency and long-range credentials
Each band suits different access equipment. Knowing the band is the first step in any compatibility assessment.
Low frequency (125 kHz)
Common in older residential proximity cards and fobs. Short read range, simple architecture and widely deployed at building entrances.
High frequency (13.56 MHz)
Used in many contemporary access systems. Supports more advanced chip architectures, where compatibility depends on the specific reader and encryption layer.
Long range (UHF)
Passive UHF tags for windshields and headlamps, read at distance by community gate equipment. Placement and vehicle type affect read performance.
