Slim BLE Work Card Badge ID-BLE-S25 (AOA, 4.3 mm)

A slim BLE work card badge with AOA positioning

The ID-BLE-S25 is a white Bluetooth Low Energy badge the size of an ID card, 85.55 × 53.95 mm, only 4.3 mm thick and 20 g. Staff wear it on a lanyard like an ordinary employee card while it broadcasts iBeacon and Eddystone frames on the licence-exempt 2.4 GHz band (2400–2483.5 MHz), up to 100 m in open space.

It is one of the AOA-capable models, so with ID-AOA-GW25 anchors the wearer can be located to within a metre.

Two ways to locate the wearer

• Room or zone: ID-BGW-02 gateways hear the badge and report its signal strength (RSSI) over Ethernet, Wi-Fi or 4G; comparing readings across gateways places it to about 10 m. A phone running a BLE scanning app also sees it.
• Sub-metre: ID-AOA-GW25 AOA anchors measure the angle the signal arrives from and fix the badge to 0.1–1 m. One anchor covers a radius of up to about twice its mounting height.

You can start with gateways and add anchors only where precision matters; the badges stay the same.

Power, protection and options

The 850 mAh Li-Po (3.7 V) is rechargeable; its 3-year rating applies at 0 dBm with a 500 ms broadcast interval. The card is IP67 and works from −20 °C to +65 °C. An accelerometer is available as an option, and broadcast settings are changed from the Identium Connect app.

ID-BLE-S25 or ID-BLE-C08?

Pick the S25 when a thin, light, IP67 badge matters most and RFID is not needed. The ID-BLE-C08 adds RFID tag support in a 7 mm, 42 g card that is life-waterproof rather than IP67, with a 1500 mAh battery. Both support AOA. See the full range under BLE wearables and work cards.
