A QR code is generated out of your digital card. Let someone scan your QR code and your contact gets directly your contact information. If you have added social profiles, they will be transmitted, too. If your contact hasn’t got the Nimple app, he can use an usual barcode reader to get your contact information.
Within the Nimple app you can scan other QR codes. You will get other digital cards with one step. The scanned contact information is saved in the Nimple app. You can use it at any time.
