The amount of data that can be stored in a QR code depends on the type of QR code and the encoding used. QR codes come in several versions, ranging from Version 1 to Version 40, with each version having different size limits and error correction capabilities. In general, the more data you try to store in a QR code, the larger the code will be and the more difficult it will be to scan. Here are some estimates of the maximum amount of data that can be stored in QR codes: Version 1 QR codes can store up to 25 alphanumeric characters. Version 40 QR codes can store up to 4,296 alphanumeric characters. However, these are theoretical maximums and in practice, the amount of data that can be stored in a QR code will depend on factors such as the quality of the code, the scanning device used, and the level of error correction used. It's worth noting that QR codes can also be designed to store specific types of data, such as URLs, phone numbers, or email addresses, and these may have differen...
