Simple Keyboard Input Device, and works with Linux!
This device works as a simple keyboard input device, and as such, works with Linux and any other operating system supplied with a simple keyboard USB input driver. GETTING SCANNED DATA Do not be deceived as I was, thinking I had to use "cat" on a device file or use some additional special program for reading the keyboard input data provided by this scanner! Simply open your favorite text editor, such as VI/VIM or even terminal, or if you must office word processor, and click the barcode scanner after connected with the supplied with the barcode scanner's supplied 2.4Ghz USB wireless device. USEFUL SETTINGS Some useful settings will be turning off the vibration notification, turning down the scanner's beep volume, adding or removing the carriage return terminator at the end of the scanned barcode. All these settings and more, can easily be switched using the barcode scanner's manual and scanning the setting's associated QR or bar code. Best to keep these settings on-hand and/or duplicated at your designated scanning areas. MAKING USE OF THE DATA TODO Although the text/ASCII alphanumeric characters are easily attained, doesn't seem to be any popular inventory database system for consumers, except Grocy and Gcstar. Both seem to have limitations, with Grocy being more easily adapted for inventorying anything. LINUX The USB wireless device is a 2.4Ghz(?) USB wireless device having a 0581:011C USB vendor/product code. The USB device will provide a /dev/input/event device file, linked to something similar as /dev/input/by-path/pci-0000:00:1a.0-usb-0:1.3:1.0-event-kbd device file. TODO: One will likely need to convert the binary serial data to text for use within a script? PROS Easily configured and utilized barcode scanner, operating system agnostic! CONS 1) The accuracy is likely slightly off sometimes, likely due to the scanner trying to read more than one barcode type at once. So likely best, if you're using consistently one type of barcode, use a scanner for that specific type of barcode rather than a multiple type barcode scanner. 2) Seems like a cheap grade of plastic is used for the exterior, or not as commercial/durable grade plastic used. 3) The plastic holder appears to be readily mountable or used on a desktop, however the plastic holder does not seem to be designed to be mounted to a wall! Or, if holder is mounted to a wall, it's going to haphazardly stick-out from the wall by nine or more inches! This is likely a significant oversight during engineering? 4) Made in China. On the flip, I rarely give good ratings for explicitly made Chinese products. This product, so far, just works with a few exceptions. 5) Not many barcode scanners can read all of the available types of barcodes on the market. Think this one of the very few on the market currently. 6) Performing a search for scripting or software making use of barcode data for database inventory for consumers seems to be significantly lacking. My guess, most are sitting back and waiting for the stores to implement a system of providing consumers already scanned barcodes, and automagically transferred to their private home inventory database. This would be by far much easier, than having to re-scan every item purchased again and again and again! Just send us consumers a list of the barcode scanned alphanumeric characters via Email, and have our home inventory database automatically read in the data. Then consumers only need to negate the item once they use or pull the item from their inventory.

Great for Amazon ASINs
I have been using this item for about a month and so far it has been great. I am a seller on Amazon and use it to scan the ASINs of the products that I ship in. It is quick and responsive. I know it has a lot of settings but for me it worked straight out of the box with the factory settings. I have literally scanned thousands of items. Also use it for barcode scanning. Happy to have a good product like this to help me.

It Does What I Wanted, Without Issues
This scanner just works, coming with all the features I needed. I will admit that I have some experience with wedge scanners, so maybe it was easier for me to use. Specifically, you configure it by scanning the barcodes in the manual, and there's a lot of options The only thing I wish I could do is have the ability to support USB Wireless and Bluetooth at the exact same time, instead of having to switch modes. But that may just be a limitation of the hardware itself, and if that's the worst there is, no issues from me. For the record, these kind of devices usually act like a keyboard, "typing" out the characters scanned. In the case of Bluetooth devices, this is done with the HID configuration

Works great. Tried Win10(usb), Raspbian(2.4g dongle), and Android with Bluetooth HID.
-1 Star for lacking basic directions. Over all great product. For those complaining about lost instructions and codes. Just download the manual and scan the codes off the monitor from te pdf file. I made a cheat sheet.jpg with just qr code settings for fast option changes. You can go wireless and upload the data when done, or upload/print in real time one at a time.

Disappointed – Stopped Working After Minimal Use
We purchased two (2) of these Tera Barcode Scanner Wireless 1D/2D/QR scanners in August 2024 for use in our Adult Day Program library. The intent was to support clients learning basic library and checkout skills, and having an on-site scanner was a great hands-on learning tool. Unfortunately, we used only one (1) scanner to log books into our Day Program library. Since that initial use, the device has not worked again. We have plugged it in multiple times, but it only shows a red light on top and will not scan. It is disappointing that a product with such limited use would stop functioning entirely. This was not heavy or commercial abuse—just light, structured use in an educational setting. The loss of functionality has shut down an activity that was both meaningful and instructional for our clients. We are very disappointed, especially given the potential this product had for skill-building and independence training. At this time, we cannot recommend it due to reliability concerns.

This is the best barcode scanner you can get up to $150
This is a great product and the price is even more insane. This product is very good. it scans fast and quick and I can't believe how low price this is. I mainly use it as Bluetooth wireless mode adding barcode using my laptop. very easy to setup, very easy to use.

Some Worked, "Support" Useless
We purchased 10 of these after upgrading our POS system to read QR codes. They come with a booklet full of barcodes to program each scanner to work for you (i.e. continuous scanning vs pulling the trigger for each scan). We had five changes we needed to make for each one so that they were "on" all the time, didn't need to pull the trigger, turned off the unnecessary light, didn't make noise and scanned all text in all caps. A couple of them worked immediately after scanning the correct programming barcodes from the user manual, about half of them worked after trying a few times, and most of them worked eventually. Two of the scanners we purchased absolutely would not save the programming we put in, no matter how many times we tried. I contacted the support and they only sent me a QR version of the barcodes we were already scanning (which still did not work). No matter what we do for those two scanners, after 5 minutes they reset back to the factory defaults. We are past the return window, so we now have two scanners that don't work how we need them to. Would not recommend if you want your barcode scanner to be always "on". If you pull the trigger every time you use it, these would work fine for you.

Klasse und extrem einfaches Setup
Super einfach zu bedienender Scanner. Zum einrichten einfach die QR Codes aus der Anleitung scannen, fertig. Besser geht es nicht.

It's ok
It does what it should, but it is not very accurate or prezise when Scanning. If multiple Bar Codes are near one another you have to Scan the Code multiple times and angle the Scanner multiple times differently to catch the correct Code.

scan multimode correct !
rien a redire sur la livraison parfaite amazon ultra rapide. petit prix pour un lecteur code barre usb filaire / sans fil 2.4ghz comme une souris avec un dongle usb ET Bluetooth. le câble usb se branche dans le manche, c'est un simple câble usb type imprimante de qualité tres moyenne qui n'est pas particulièrement souple ni de ressenti de qualité par rapport à des produits plus professionnels. Le mini dongle wifi générique se loge en bas du manche également et reste apparent, pas d'infos particulières dessus. je ne l'ai pas testé mais aucune raison d'avoir un soucis. ca fonctionne comme un clavier souris sans fil Testé directement en Bluetooth sans effectuer aucun paramétrage. il suffit d'appuyer sur la gâchette quelques secondes pour que le voyant se mette a clignoter et le scanner devient détectable sur votre pc / mac, le jumelage est très rapide. Le socle est en plastique rigide, pas très lourd, pas lesté, mais il est possible de le fixer avec trois vis Par défaut le scan des codes barre a fonctionné directement, attention si le clavier du pc est en minuscule il renvoie les signes alpha et non les chiffres sur un clavier fr. il faut modifier un paramètre avec un code barre pour lui dire de toujours scanner et envoyer les chiffres Je n'ai pas eu besoin de le charger pour l'utiliser. Pas de bouton marche arrêt. il se met en veille tous seul en quelques minutes et se réveille / reconnecte des l'appui sur la gâchette. Je vais l'utiliser a demeure sur son support , ce qui n'est pas pratique pour l'accès à la gâchette mais comme on peut voir en l'ouvrant il est très simple de monter un bonton poussoir externe à la place (par exemple un bumper au sol) ce qui permettra de le laisser à demeure sous tension en veille à l'atelier sans activer la fonction scan permanent. pas encore testé le scan des qr code ni la lecture sur écran Pour le prix je n'en attendais pas tant !
