...without having to re-mortgage the house!
The cheaply available modules (125Khz 20-50 quid) only read about 150mm max.
The next step up seems to be 13.56Mhz long range reader for $500!
I only need to read the tags (writing is not necessary), and it needs serial output to an AVR (so no USB etc)
The budget is about $100 USD, but can go a little higher for the right product.
If anyone knows of anything that might do the job, please let me know.
Thanks in advance!
