How long will it typically take to scan a card?

This is heavily influenced by your own data connectivity at the time of checking the card. However, it should typically take no more than 2-3 seconds.

It may take a couple of minutes when scanning on site for the first time, but after that it will only take a few seconds. When you open the RIW App for the first time, it will take a few moments to synchronise the site data.
