- Reviewed in the United Kingdom on 22 July 2020I bought this to use for a Raspberry Pi project. Plugged it in, ran the relevant code, it works. Bit pricey, but seems to be the best value for the job.
You could get the same reader writer from other sellers on here for ever so slightly less but this listing was recommended to me and now I’m happy to recommend it to others.
- Reviewed in the United Kingdom on 20 May 2019I tried a few NFC tags supplied with and seperate bought tags and have been using them to learn the ropes.
The bundled software isnt that helpful but there are 3rd party vendors who disribute their own software to practice on.
- Reviewed in the United Kingdom on 5 September 2018very satisfied with the product, just that, the problem is software :))
- Reviewed in the United Kingdom on 15 December 2018I have bough these readers few months back and I was surprised with their quality. I have done many modifications to the hardware, soldering, unsoldering and never had any problems. The buyer should be knowledgeable to install additional packages such as ccid, libnfc, pcsc-tools.
- Reviewed in the United Kingdom on 17 June 2021Works perfectly
- Reviewed in the United Kingdom on 25 February 2019Seems to work fine. Good range and works well with a friends xNT implant.
- Reviewed in the United Kingdom on 2 August 2019Never got it to work, binned it
- Reviewed in the United Kingdom on 2 February 2018Works as described, though the supplied MiFare tags are not readable on most devices.

5.0 out of 5 stars It just works!
Generous USB cable length. Solid USB-A connection. NTAG215 was detected at 60mm. Software comes on a Mini CD but I used “NFC Tools” on Windows 11 Pro 64 bit (available for all platforms) instead. Direct shipping from China to Canada (GMT -5) took 8 days.

Den fungerade som den skulle, egentligen, men kunde inte lägga in inläsningen som en textrad.
