Hi All, I was in need of a barcode scanner for one of the apps I was building and know there has been a bit of discussion around the implementation of a barcode scanner on Thunkable X… anyway I know this isn’t quite a barcode scanner, and has its flaws, but seems to work okay for me, I have added screenshots and explanation below: As you can see you call the camera, and take a picture of the barcode, use the “Photo” output of the camera as the “Media” input of the MediaDB (cloudinary). You can then use this nifty little API Free OCR API to create your own API key. When you scan the barcode you won’t be actually scanning the barcode but the numbers beneath the barcode as this is an OCR reader. Once this is done you want to set your Web_API URL as https://api.ocr.space/parse/imageurl?apikey=YOURAPIKEY&url=mediaURL You need to use your own API that you have set on Free OCR API and your mediaURL output from the MediaDB Then you will call back the result of that API and parse it like you would with any JSON format so that you only receive the number of the barcode. I have also added a Alert, so that it confirms with me whether the number matches the barcode, this is because if you scan more than just the number on the barcode the OCR will attempt to read the text, [image] Let me know how you go, I’d still like a real barcode component though :slight_smile: Jacob

The thing is cloudinary has an OCR function. The problem with X is that after an upload we only get the MediaURL and not the entire JSON response back from Cloudinary. If we got the actual response, we can then use the OCR function within Cloudinary more efficiently. [image] What I have to do now, is a separate call to the admin api of cloudinary, to get a list of files uploaded, then search for the mediaURL, then I can find the public_id. After that I can do an UPDATE query and get the JSON response that had the OCR, even though all that information was in the original response. So here is the request. Please put a “response” option for the MediaDB (being Cloudinary)

Is there any way I get have a copy of this app to modify for a certain project I am doing?

Hey! Sure I’ll message you a remix link shortly!

pasenmelo porfa el remix para editarlo no me sale

Hi @ana_luisa_aguilar, which remix link is not working for you?

i try to do this tutorial but its not working… i want this remix please

Ah, ok. Take a look at our blog post that has an example of how to create a barcode scanner in a similar manner. The remix link is at the end: [image] Creating a QR Scanner App in Thunkable X Making a portable QR decoder using a RESTful API and no code at all! Reading time: 4 min read
