| Summary | 0011755: Design decision: should zero payments be possible? -> allow for zero payments in IOS | ||||
| Description | In Android CHF 0 works, in iOS CHF 0 is not allowed by GUI. The same is valid for other currencies. | ||||
| Additional Information | Own opinion: for testing purposes against (live and production systems), w/o balance, zero payments useful. Also for people to see it works "in principle" (if wallets not yet funded). | ||||
| Tags | design-required, discussion-needed, wallet | ||||
| I'd say: Definitely yes, especially when we have tokens as well. | |
| OK, assigned to @MarcS as for iOS also to allow this; amt field is grayed out when zero. | |
| Paying with tokens, but without money is already possible. E.g. go to shop.TEST.taler.net, choose a chapter, instead of paying テ0.5 for the chapter buy 1 month of access for テ10 to receive a token, then try to buy another chapter. It will automatically get paid with the token. For people to see how it works "in principle", we have DEMO. For testing purposes, I will make zero payments available in dev-mode. | |
| v1.6.15 allows both pay-template and p2p to continue with amount:"0", when dev-mode is on. Pay-template succeeds, but p2p will result in wallet-core error (amount of zero not supported). | |
