This is essentially a beta right now. If you try this and it does not work, I would appreciate if you could contact me with the type of phone and app settings you were using.

Rhombus uses the Squareup magnetic stripe card reading dongle to read any standard format magnetic stripe card. You can use it to see what information is on your credit cards, loyalty cards, driver's license, and more. When a credit/debit card is scanned, it attempts to determine the issuer. In the screenshot above, you can see a redacted result of scanning an expired visa card. One of the other screenshots shows a scan of a Main Event fun card.
Rhombus reads track 2 by default, but will read track 1 if the card is offset by a small shim.
Rhombus does not have internet permissions, so it cannot send out any information about cards you may scan.
