Plug into USB port (I tried Win 10 and, Raspbian), open a text editor, scan a tag, it reads the tag ID and squirts it to the text editor. I followed instructions from another very kind reviewer: (Alex in Germany said: If you want to control the device under Linux e.g. a Raspberry Pi can intercept the input e.g. with the python “evdev” module with the command: dev = evdev.inputDevice (“/dev/input/by-ID/USB-hxgcoltd_27db-event-kbd”) ) Using this guidance it was straight forward to capture the read-events, send them into my python code and parse to reconstruct the preprogrammed tag number. That capture instruction from Alex should be made more widely available IMHO. It's about 6cm x 9.5cm, light and compact. I didn't subject it to intensive use, so can't talk about durability. Review: Works well, only downside is slightly cheap feeling - I plugged it in and it worked straight away. Only downside is the case is a little cheap feeling so I'll need to add some weight to it to use it in practice. ## Features - Small size, plug and play.

Only downside is the case is a little cheap feeling so I'll need to add some weight to it to use it in practice. ### ⭐⭐⭐⭐⭐ Just plug in and play *by F***Y on 9 January 2020* Can’t complain for the money. Plugged it in and it worked. Reads from a few centimetres away from the tag. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/48051749-usb-rfid-reader-125khz-em4100-tk4100-card-tag-id-reader](https://www.desertcart.pl/products/48051749-usb-rfid-reader-125khz-em4100-tk4100-card-tag-id-reader) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-24*
