Fobs solved the problem cards created: people forget badges but rarely forget keys. The 1346-style teardrop fob is a passive 125 kHz credential in a molded, weather-tolerant housing sized for a keyring, and it is programmed exactly like the cards on the same system — same facility code, same number sequence, same format. Because it is passive, there is no battery to die; because it is molded, it survives pockets, weather, and years of daily use. Read range on a fob is naturally shorter than on a full-size card (the antenna coil is smaller), which in practice means presenting it an inch or two closer to the reader. We supply unbranded, compatible-by-specification fobs programmed to your system's format and number range — order them alone or mixed with matching cards in one batch, with no dealer account required.

What is a 1346-style key fob?
A compact, battery-free 125 kHz proximity credential in a molded keyring housing. It carries the same programmed data as a proximity card on the same system — facility code and card number in your panel's format — just in a pocketable form.
What read range should I expect from a fob?
Slightly less than a card, because the internal antenna is smaller. On typical wall readers that means roughly an inch or two of presentation distance; long-range readers used for parking still read fobs at reduced range compared to cards. This is inherent to all fobs, ours and originals alike.
Can compatible fobs and existing cards run on the same system?
Yes — the panel only sees format data, not form factor. Facilities commonly issue cards to staff and fobs to tenants or contractors from the same number sequence. We program both from a single specification so the fleet stays consistent.
How do I order fobs that match my current cards?
Send your facility code and the next card-number range, or photos of a current card's printed numbers. We verify the format, program the fobs to continue your sequence, and ship them enrollment-ready.
