Tzone's 2G fleet tracker (the AVL19) with a built-in 2.4G RFID reader, temperature-tag support, and a relay cut-off · reads driver ID, cargo temperature, and position together, all decoded by Traxelio.
Data Points
Alerts
Vehicle Types
Fleets that need more than a dot on a map. Its 2.4G RFID reader logs which driver took each trip, 2.4G temperature tags watch a cold-chain load, and the relay output cuts the engine on a confirmed request. Position rides over 2G.
Yes · the RFID reader is built in, not an add-on dongle, and it pairs with Tzone's 2.4G wireless temperature tags. Traxelio surfaces the driver on each trip and the temperature trace next to the route.
Yes, over the Tzone protocol included through Traccar. Point the device at the Traxelio server with the standard configuration command and it reports position, RFID, temperature, and I/O without a firmware change.
For a cold-chain or shared-driver fleet, yes · 2G covers it across Senegal and the RFID plus temperature combo is genuinely useful. For plain location-only tracking it is more device than you need · a GT06 or TK303 is cheaper.
Overview
The Tzone TZ-AVL19 (often searched as just "AVL19") is a 2G vehicle GPS tracker built by Shenzhen Tzone Digital Technology around driver and cargo identification · a built-in 2.4G RFID reader, 2.4G temperature-tag support, and a camera connector sit alongside a cut-off relay. It reports over the Tzone protocol that Traxelio decodes, so a fleet gets who-drove, cold-chain temperature, and remote immobilization on one dashboard.

The 2.4G reader only pairs with matching 2.4G RFID tags · a 125 kHz or 13.56 MHz office badge will not register. Use the Tzone tags, and mount the reader where the driver naturally passes the tag.
The 2.4G temperature tags are wireless and range-limited · a tag deep in a metal reefer body can lose the link. Place the tag and the AVL19 so the signal path is not fully blocked by metal.
The Tzone protocol carries RFID, temperature, and I/O in extension fields · confirm the firmware has them enabled and that the server command requested the extended report, not position-only.
