#173635 - 500mm Read Range Responding to: ???'s previous message |
At 125KHz you need quite a large magnetic field to energise tags at 500mm distance.
It's much more than just putting a RFID IC on a board, it requires LF RF design and tuning. Do you have this experince? If your customer just wants 1 reader - then there are plenty of RFID readers and tags on the market. ===> Why reinvent the wheel? <===== Consider - designing external physical enclosures that can reduce the read range requirement much less than 50CM. Consider - RFID Anticollision is tricky business and with RF you may get miss reads. Is the customer expecting 100% RFID reader reliability autonomously (without human intervention). Consider that Wallmart and Metro RFID systems are not 100% reliable (miss reads), even with the most sophisticated readers. Joe |
