An IRMA card can communicate to computers via card readers or directly using the so-called NFC technology. From a small distance, say a few millimetres, a card and a mobile device can “talk” to each other. This technology makes it easy and fast to check whether you have certain credentials on your IRMA card.
This is how you can show at a hair dresser, for instance, that you are a student in order to get a discount. Note that you don’t reveal your name – you just show your photo and the attribute on the card proves that you are a student.
The three screens shown above describe:
- Stand-by: The verification device is waiting for a card;
- Verification: The device is communicating with the IRMA card for about 1-2 seconds;
- Result: If the card holds the necessary attribute, the verification device will approve it.
However, it is also possible that something goes wrong. It might be that a transaction error occurred, in this case you’ll be asked to try again. The other alternative is that your card does not contain the student attribute, and hence the verification will fail.
