![]() ![]() We recommend QR Code & Barcode Scanner, which works quickly even when you’re some distance from a code and doesn’t require an internet connection. On older phones that run Android 7 (Nougat) or earlier, you’ll need to install a third-party app to scan QR codes. Alternatively, install the Google Lens app to add a shortcut to your home screen. Either long-press the Home button or say “Hey Google” to open Assistant, then tap the Google Lens icon. If your phone is running Android 8 (Oreo), you can scan QR codes with Google Lens via Google Assistant. How to scan a QR code on older Android phones You can also access the "Scan QR code" option by swiping down from the top of your screen to open the Quick Settings tray. On Samsung phones, which use their own technology for scanning QR codes, ensure that "Scan QR codes" is turned on in the Camera app’s settings. Go into your camera app’s settings and switch on Google Lens there. This is just a simple step-by-step guide for a way to achieve this, but this is just one of a few ways you could potentially achieve this.If nothing happens when you scan a QR code with your camera, you may need to activate Google Lens manually. ![]() Each QR code will have to be generated to have the cell range in the URL so that the PHP script can fetch the relevant information. The PHP page can then generate HTML content which is returned as the response to the request which will be viewed in the browser that is opened by the URL in the QR code. You can find the reference for Google spreadsheets here, and the value for setting and gettinv cell values here. Where $range is the range passed via URL. For example if you passed something like ?range=a1 in the URL you could take the parameter and call $response = $service->spreadsheets_values->get($spreadsheetId, $range) The script should be designed to take in a range in A1 notation (for example Taking this range, you can follow the PHP Quickstart tutorial to connect to the Google Sheets API and fetch values of cells or ranges of cells based on the ? parameters you passed in the URL. You can set up a php server-side script which can take ? parameters in URLs for the cell or cell range you want to be able to read. You can use this to your advantage to build a workaround to grap the data you're looking for. Most QR readers will automatically open a web browser when a QR code containing a URL is scanned, which is the extent you're really able to do though. QR codes are just a type of machine-readable barcode containing information, and by using one alone it isn't possible to run a script or program. This spreadsheet is a Google Spreadsheet i.e., an online document and should be updated as and when the QR codes are scanned.Īdditional challenge being, how do we select which row of the Scanned Info columns to place the information so that the column remains in the same order as the Name column (which is not arranged alphabetically). not bound any special apps) and get the data embedded in the form (in a specific column here- Scanned Info column). Would be nice to be able to use a regular android phone to scan the QR code (i.e. Now, If one were to scan these 3 QR codes, how could I extract the information of the QR codes (names in this case) and enter it under the scanned info column? As a sanity check, Scanned Info column should be identical to the Name column but scanned info is directly filled via QR code scans while for the sake or argument, other columns were manually entered. Then column "QR code" is generated by using the trick from here and the QR code simply encodes the Name info per row which represents 3 different people in this case. ![]() TimeStamp, Name, Age, Email, QR code, Scanned Info Lets see we have a simple spreadsheet that looks like this: ![]()
