Reader types
Desktop/USB readers encode and personalize cards at a workstation. Fixed readers with external antennas cover doorways, conveyors and shelves for hands-free reads. Handheld (often Android) readers suit mobile inventory and field work.
Frequency and range
Match the reader to the tag: LF and HF readers for short-range cards and tickets; UHF readers for metres of range and bulk reads. Antenna count and placement largely determine real-world coverage.
Interfaces and integration
Readers connect over USB, RS232/RS485, Wi-Fi, Ethernet/PoE or Bluetooth. For software integration, look for a documented SDK and demo apps so the reader feeds your WMS/ERP or access system cleanly.
Modules and terminals
Beyond standalone readers, embeddable modules, barcode scan engines and IoT DTU/RTU terminals let you build RFID into kiosks, gates, vending and remote monitoring.

Frequently asked questions
Do your readers come with an SDK?
Yes — readers ship with an SDK and demo software so you can integrate with your own application and back-end systems.
Which reader do I need to encode cards?
A desktop USB HF/UHF reader/writer is used to encode and personalize cards at a workstation.
Can one reader handle LF, HF and UHF?
Most readers target one band. For multiple frequencies you typically use separate readers or a multi-frequency model where available.
