About Access Card Protection

Workplace Security. Protecting 125 kHz Access from Cloning.

Your key card is your key to the building, the gym, the apartment, or the secure server room. It offers convenience, but it exposes a critical vulnerability: most access cards broadcast on the 125 kHz RFID band, a signal that criminals can quietly read and clone in seconds using portable skimmers. Access card cloning allows intruders to bypass physical security measures, putting staff, tenants, property, and sensitive corporate data at serious risk. Protection for this specific low-frequency threat requires a purpose-built, engineered solution.

The Risk: How Cloned Cards Become Master Keys

Silent Skimming:

Attackers use compatible 125 kHz RFID readers to instantly copy the card's code, often without the card ever leaving your wallet or lanyard.

Total Compromise:

The building's access control system cannot reliably distinguish between an original card and a cloned one. The cloned card effectively becomes an unlawful master key, granting physical access to secure premises.

Identity Exposure:

Any personal data stored on the card can be harvested, creating further risk for identity fraud or social engineering attacks against your workplace.

Every access card carries a unique code verified by a wall-mounted reader. The simplicity of the radio signal is the system's weak point.

Skimguard’s Countermeasure: The A-Lock

Skimguard's A-Lock is the world’s first cyber shield engineered specifically for 125 kHz access cards. It resolves the cloning risk with an automatic, maintenance-free solution.

Certified 125 kHz Shielding

Uses Skimguards patened eField technology to block 125 kHz frequencies, rendering your security access cards invisible to cloning devices.

Simple, Passive Defence

The protection is always-on—it requires no batteries, charging, or apps. Simply place you A-lock next to your security access card to keep your access safe.

Zero Maintenance

This is a set-and-forget solution. Its durability ensures reliable, 24/7 protection without any maintenance or complex upkeep.

Multi-Use Protection

A-lock is capable of protecting multiple security access cards at once via Skimguards powerful eField technology.

Where to Keep A-Lock

For best protection, store your access card next to A-Lock in your wallet, purse, or lanyard. When you need to enter a building, remove the card and tap as usual. A-Lock’s design means it protects both at rest (in your bag, pocket or on a lanyard) and lets you access doors when you need to.

Practical Tips for Organisations and Individuals

Individuals:

Treat key cards like keys — keep them stored with A-Lock when not in use and report lost or stolen cards immediately.

Workplaces & Admins:

Consider card lifecycle policies (regular reissue, limited access windows) and combine physical protections like A-Lock with administrative controls (logging, two-factor for high-risk areas).

Travel & Shared Spaces:

If you carry an access card when travelling or in shared living spaces, use A-Lock to stop opportunistic skimming at events, co-working spaces or transit hubs.

Complementary Financial Defence:

Pair the A-Lock with the Global Protect Card in the same wallet to secure both your 125 kHz access card and your 13.56 MHz financial cards. Or add your A-lock to our Minimalist RFID Pod for a sleek, slimline protection solution.
