I need help finding a long range RFID modules for cheap. I have already found a couple offered by places like Ali-express or Electrodragon, but all are shipped from china and therefore have high shipping costs and long shipping times. The ones I saw were 125khz and could achieve around 2-6 feet. They use a separate coil hooked up to the chip which is nice and big and where they get their range from. Does anyone know if Sparkfun offers anything like this for the same price? Or any other place that I can get decent shipping?
I am not sure if SparkFun will have an RFID reader that matches your needs here. The only reader we carry that can get the ranges you are looking for is the [SparkFun Simultaneous RFID Reader that uses the M6E Nano and UHF frequencies. You can get, in ideal circumstances (eg. little to no interference between the tag and reader) 1-2 feet from the PCB antenna and with an external antenna you can get up to 16 feet.
That said, there are some very important interference sources to factor into your range that we outline in [this section of the Hookup Guide. Namely, you need to have minimal interference (no metal, water, etc. in between the tag and antenna), proper tag alignment over open air and clean and powerful power supply to maximize your read distance. If you are interested in learning more about the Simultaneous RFID Reader to determine whether or not it will work for your project, I highly recommend reading through the full Hookup Guide as it will go over hardware, powering the board, Arduino examples and much more.](https://learn.sparkfun.com/tutorials/simultaneous-rfid-tag-reader-hookup-guide/example-10---range-test)](https://www.sparkfun.com/products/14066)
