NFC ACR122U Contactless IC Card Reader Writer/USB + SDK + IC Card

Arrived quick, no problems scanning my cards. Used with NFC Tools on PC.

One step closer to finishing my mech

I use this specifically for Dance Dance Revolution and it works perfectly.

Device detected on USB but reader interface never initializes. PC/SC repeatedly fails with LIBUSB timeouts. Unable to use device despite resets and power cycling. Likely defective. Would not recommend.

Shipped to the Netherlands. Went smoothly. Product works fine (we use it to create Skylander NFS on mifare cards.

This thing's been wonderful, bought it to write RFID tags for my 3D printing spools, works awesome. Only thing is I need to find a program that works with it so that I can write tags for other things such as luggage tags and things like that

Works great

Okay, so the product DOES work despite all the terrible reviews. BUT yes the software a bit cryptic alongside the directions. Since there are many different files & whatnot. One of the PDF’s contains the most amount of info that helps the most at explaining what needs to be done. When I set mine up I found that when you connect, choosing “Shared” “T1” allowed me to write to NFC technology (that’s my sole use case). When looking at the directions I tried to ‘quick search’ the differences between T1 T0… no docs explained them nor for Shared or the other options which I am drawing blank as we speak. I am personally calling this product cryptic maybe because I do not fully understand its other use cases which makes me more ignorant than helpful but as I said, my sole use is for NFC & it works for NFC. Once you get it to work fully it’s easier to repeat for additional use. Overall, it’s not a bad product but they should provide video tutorials for the slower customers who are new at this (me). I’d agree for value for money since it’s one of the cheaper options & it reads cards very well. NOTE!! The 3 cards they send are NOT NFC.. I think they are just PVC which contains no technology so when you read the comments saying it’s doesn’t read, they are trying their own. I know this for sure because iPhone App Store has a NFC card read/writer app that I used which has been able to read every nfc piece of tech I have until those blank cards they send. Word of advice: DO NOT SEND THOSE BLANK CARDS!!!

Super qualité

Plugged into PC, installed NFC TOOLS write all 3 of the cards with a URL and tested all phones read them straight away. Bought some little sticker disks and they also all worked! Perfect! Having said that I did not know that my pixel 9 pro also writes cards and tags but it's nice to have a PC option.

Ich nutze den Lianshi kontaktlosen IC-Kartenleser NFC ACR122U gezielt zum Erstellen und Beschreiben eigener RFID-Tags für meinen 3D-Drucker und bin damit sehr zufrieden. Der Leser wird per USB sofort erkannt und arbeitet zuverlässig. Das Auslesen und Beschreiben der Tags funktioniert sauber und reproduzierbar, was gerade beim Anlegen eigener Filament- oder Material-Tags extrem wichtig ist. In Kombination mit dem mitgelieferten SDK lassen sich die benötigten Daten problemlos schreiben und testen. Die Verarbeitung ist hochwertig, nichts wirkt billig, und die Reichweite ist für diese Anwendung völlig ausreichend. Praktisch ist auch, dass direkt eine IC-Karte beiliegt – ideal zum Testen oder für erste Experimente, bevor man eigene Tags nutzt. Fazit: Für alle, die eigene RFID-Tags für ihren 3D-Drucker erstellen oder anpassen möchten, ist dieser Kartenleser eine sehr gute und zuverlässige Lösung. Macht genau das, was er soll – klare 5 Sterne.

Works terrifically for skylanders
