BlindSquare QR's. What happens when you don't have WIFI/Cellular-data when scanning a QR?
If you have scanned the QR previously, you always have text information available through Cacheing.
1. If No signal – Then QR info is spoken from previous scan,
2. If QR messaging has been updated since last scan and there is no signal, the previous messaging is read.
3. If internet access IS available, new data will be updated and the cache refreshed.
For QR's that connect to other cloud-based information products (ie, websites, surveys, streaming YouTube videos), this information is not cached to reduce storage requirements on the device.
