How should I charge for this product? https://getmagiclink.com I have built a simple tool to create mobile wallet card in minutes. This can be used for events, offers, membership card etc. You can click to add to wallet via an ad on instagram or email or scanning a QR code. You can also see the metrics around how many users Option 1: $99 a month subscription Option 2: Pay per use - $1 per card saved to wallet. Any other options?
