RF-HDT-DVBE: Best Reader/Antenna/MCU to pair with HF tag

Part Number: RF-HDT-DVBE

Hello,

I was hoping to get some guidance on what products might be most applicable for my use case. 

I am designing a system that should be able to read a transponder at a distance of about 5-10 ft attached to the side of a crate (no special environmental characteristics). Because of this, and from what I have read, a 13.56 MHz transponder would be ideal for the distance required. Somewhat arbitrarily, I chose the RF-HDT-DVBE transponder (mostly because of its size). 

The reader, antenna and MCU I know less about, and was wondering if I could get a recommendation on what products would suit my transponder choice. Since all 13.56 MHz readers should work, is there an antenna that would pair well with the hardware? Likewise, is there an MCU that would be best?

Thanks in advance.

    Hello Brendan,

    For 5-10 feet, you aren't going to have much luck with HF RFID. Maybe if you bought some very expensive high power readers you could get a few feet but even those would struggle to manage 5-10 ft.

    LF RFID is an option, but you'll need a pretty big antenna and a good deal of output power to make that work.

    Your best option for that range is to use UHF RFID. TI doesn't make products for UHF RFID though. But if that's the read range you want, I'd encourage you to seek that approach as neither LF or HF RFID are intended to be used in such applications.
