The DLP-RFID2 is a low-cost, compact module for reading from and writing to HF RFID transponder tags via an internal or external antenna. It has the ability to both read and write data in addition to reading the unique identifier (UID).
I obtained a few of these units from a liquidating Silicon Valley lab.
PLEASE examine all the pics on this page.
Thanks for having a look.
This was in sealed packing, but I opened one for pics.
