Scan n Gen vs Operational Amplifiers Pro

Scan n Gen is the fastest scanner for Barcode/QR, NFC reader and OCR/text reader. It can also create Barcode/QR code which can be saved and shared. This is an essential app for every iPhone & iPad device. Additionally, it has an OCR (Optical Character Recognition) function to recognize the characters from an image. You can also save the generated text and/or share it through multiple options. Scan n Gen is extremely easy to use: Steps: 1. To scan barcode simply point the rear camera of your device to scan the QR, barcode, or text that you want to decode. The app will automatically detect, scan, and display it. No needs to press any button, take photos, or adjust the zoom. 2. Create QR Codes and Barcodes and save them or share them through email, WhatsApp, Facebook, and more. Generate Codes from URLs, Text Messages, Phone Numbers and/or any free Text. 3. Read data from NFC chips by tapping your phone on a NFC chip. 4. OCR Real-Time Text Scanner scans and extracts text at very high reading speed with the highest accuracy. Features: Scan n Gen scans and read all types of QR/ barcode types (supports multiple formats). Using the app, you’ll be able to generate your own barcodes. With Scan n Gen, you can easily share your barcode with your friends. It also scans and reads NFC Tags. It even supports a Flashlight feature. OCR functionality - Scan and read the text from images stored in your phone or live using the rear camera. Easily convert images to texts so you can edit, save, and share them. Required Permission: Camera: Scan n Gen needs permission to use your camera to scan images/docs/QR/barcodes. Gallery: Scan n Gen needs permission to use your phone gallery so you can easily scan your saved images/docs. Our Scan n Gen App is available with full features as mentioned and it’s free. A must-have app for your iPhone & iPad! Download it now!! For any questions, or if you need assistance, please contact V Group’s Digital team at: digital@vgroupinc.com
