Yoco card machines uses very little data to process a payment
One transaction uses approximately 50 - 100 KB of data.
This means you can run 10 - 20 transactions per MB, or 10 000 - 20 000 transactions per GB.
IMPORTANT: The amount of time it takes to process your transaction is dependent on your Internet speed, whether using WIFI or mobile data. We suggest using 3G internet speed or faster.
