I’m building my own system for the store where I work, including inventory and product pricing.

Right now this system can already be accessed through a phone and even use the camera to scan barcodes and check products. The problem is that this ends up not being very practical in day-to-day use.

The idea would be to have something attached to the employee’s belt or in their pocket where they can simply:
pull it out > scan > instantly see the price and stock.

Because on a phone you usually need to go through the whole process of:
opening the app, going to the products tab, opening the scan function, waiting for the camera to respond, trying to focus to read the barcode, and only then seeing the information.

The store is relatively small, but employees often need to check prices multiple times for a single customer, so I wanted to create something faster and more direct.

I did some research and noticed there’s basically no affordable portable barcode scanner with an integrated screen capable of showing price and maybe stock information.

So I started thinking about whether it would be possible to build one myself that would be portable, have a barcode scanner, and a small display just to show price and stock.

Literally like those supermarket price checkers mounted on walls, but portable.

I already have the system and the API, so theoretically the device would only need to scan the barcode and query the API to display the price/stock.

Does anyone know if something like this would actually be possible to build, or what the best way to make something like this would be?

I’m considering using an ESP32 for this project.

Estou montando um sistema próprio pra loja onde trabalho, e dentro desse sistema tem controle de estoque e preço dos produtos.

Atualmente esse sistema já pode ser acessado pelo celular e até usar a câmera pra ler código de barras e consultar os produtos. O problema é que isso acaba não sendo tão prático no dia a dia.

A ideia seria ter algo que ficasse ali preso na cintura ou no bolso do funcionário, onde ele simplesmente:
puxa > bipa > já vê o preço e estoque.

Porque no celular normalmente o celular precisa fazer todo o processo de abrir o app, abrir ir na aba de produtos, ir na função de leitura, esperar a câmera responder, tentar focar pra ler o código e só então ver as informações

A loja é relativamente pequena, mas muitas vezes os funcionários precisam consultar preço várias vezes pra um único cliente, então queria criar algo mais rápido e direto.

Pesquisei um pouco e vi que praticamente não existe um leitor de código de barras portátil com tela integrada pra mostrar preço e talvez estoque por um preço acessível.

Então comecei a pensar se seria possível montar um eu mesmo que fosse portátil, tivesse um leitor de código de barras e uma mini tela só pra mostrar preço e estoque

Literalmente como aqueles verificadores de preço de supermercado que ficam presos na parede, só que portátil.

Eu já tenho o sistema e a API, então teoricamente o dispositivo só precisaria ler o código e consultar a API pra mostrar o preço/estoque.

Alguém sabe me dizer se isso seria possível de fazer ou qual seria a melhor forma de montar algo assim?
