'Tap to pay' is the standard for instant, seamless transactions. This is a massive step for mainstream adoption. Keep building!
A better user experience than QR codes is certainly needed, but is 'tap to pay' truly better than fiat? The key will be ensuring it's as fast, ubiquitous, and low-fee as existing credit/debit networks. Excited to see the launch!
Agreed. What technology is enabling the 'tap to pay' functionality here? Is it NFC, or something proprietary? Seamless payment is key, but the security layer is critical.
nfc + cashu
This is gonna change the game.
I ve been thinking on how people could use ecash tokens physically and securely in a doomsday scenario where internet and electricity is off and tap to pay seems to be the solution. How?
1. You have a doomsday app that lets people send in their ecash inexchange of an encrypted representation that token using public key cryptography.
2. The encrypted token is then loaded on to a card for use.
3. Marchants and other people have devices that can verify the authenticity of the token while the exchange them.
4. When internet is back, they can then redeem their ecash using the same doomsday app that gave them the encrypted tokens.
I don't really know if this is a good idea. But my problem was " how can we exchange ecash tokens physically for prolonged period of no internet while trusting the validity of the token without access to the mint?"
