Inconsistent

It’s great to have a card identifier for collectors- but it doesn’t always get the card right. I have scanned fronts and backs and gotten different versions and prices. The prices seem to be overly high based on researching the card directly on the internet. If a company can harness true values - and be consistent with pulling the correct card scanned- sky is the limit. Great format, easy to use, and love the idea. Just not sure is pricing is accurate enough. Example- TCG player online has different prices for the card than what scanned on the app. How do you tell who is correct?
