If you wanted to send me a monetary tip for my excellent Mastodon posts, which platform would you prefer to use?

@revk @Edent I am not spending £1 per message to find out.

@davidgerard @duncanlock @tante @steve ah, I misread their developer documentation.
I don't know which merchant my greengrocer uses, but they're able to charge less than a quid.

Of course, that's card-present. Looks like online payments still have a fixed fee overhead.

Thanks!

@dan @Edent By, for example, monzo to monzo, allows utf8 messages even on 1p transaction, and no fee.

@Edent The "traditional" card terminal providers like Barclaycard, Dojo, Worldpay and so on will have fee structures that incorporate a fixed "authorisation fee" and then a percentage of the payment which are likely to be different for each class of card (matrix of credit, debit, domestic, international, special case for Amex); they will happily process transactions that cost the merchant more than the transaction amount. They tend to pay out gross daily and then invoice fees monthly.

@Edent SumUp and Square pay out net daily. Stripe is the worst of both worlds; they pay out net daily but do have a flat fee plus percentage fee structure so it's possible for a small transaction to be completely eaten by fees.

(That's why, although Stripe have the best designed API for integration with POS systems, I don't support them in my POS system yet!)

@revk @Edent My problem with "open forms" like that is the possible abuse factor. I have heard of PayPal and UK bank accounts being frozen for silly messages such as "For drugs".

@Edent the only two I've actually used - because when I looked into them they didn't have some aspect that bothered me - are LiberaPay and Kofi.

@dan you can always bounce £1 between each other as a way to send a message

@revk @Edent

@steve @Edent @duncanlock yeah, lotta corner shops round here still say minimum £5. Even the ones that don't, i keep coins in my pocket so i can buy a drink or whatever without their share being eaten in card fees.

@Edent I have the app installed and played with the demo provider.
It is not widely supported yet but there are some places were it is used: https://www.taler.net/de/news/2025-04.html

First pass at some visually consistent SVG banners - all using the official brand logos.

Thoughts?

@Edent I've never used Ko-Wis Donen col. Are they any good?

@Edent Naively, looking at them cold, it might be useful if all of them had some kind of unifying common way to indicate that they are a way to tip/pay. This would allow users to get oriented quickly, even if they had never seen the platform that the person placing the badges has selected.

@Edent @Floppy Ideally it could be something in activity pub, connecting with an open kinda backend. I think it could also be useful to have paid for "followers" to see more content, as to get people in substack with a good way out.

@Edent (I am guessing.) Your home made copies of corp branding for a project?
The multinationals (none consumer facing) I have worked for are very vigilant of their brand use. Not just look and feel, but were and how it is used. IME better ask them first.

@Edent honestly I assume nobody else here would want this, but Apple Pay or Shop would be the least friction for me. I would press the button a lot. I guess it is not possible tho!

@knotnicky you're not the first to say it.
I've no idea how to integrate with them though

@tychotithonus yup. The idea they would be in a visually distinct box saying "pay me using…"
