Secondly, the legal aspect. Will this be considered as a wallet?
Anyways, loved to see it implemented by someone.
Since Small Transfers doesn't store customers' funds or allow them to withdraw a balance, the platform is not considered an e-money institution or a "wallet".
When the customers pay their balance, we immediately forward the funds to the merchants.
What happens when the charge attempt fails after initial preauth?
If a merchant successfully authorizes a charge, the amount is reserved for that merchant for a limited period. Trying to capture that amount (or less) during this period will succeed.

With Small Transfers:
- There is no wallet or funding for the account. Customers simply pay for what they owe, usually at the end of each month.
- There is a lower psychological barrier, since there is no subscription or prepay commitment. Customers who dislike recurring payments are more willing to try something new that avoids this.
- Merchants need to introduce customers to just one extra service, Small Transfers.
Some customers of Unattach (a service I built) are happily paying for the service via Small Transfers, and early feedback shows that they really appreciate this pricing model. It's worth noting that Unattach also supports the classic subscription model.As more merchants adopt Small Transfers, customers will still only need one account, making micro-billing even more convenient.
