Help : PAYMENT METHODS : PSP : Checkout is PostFinance's new PSP service

Checkout is PostFinance's new PSP (Payment Service Provider) service.
Open an account at checkout.postfinance.ch
When signing up for PostFinance Checkout as Shop Owner, you must acknowledge, at PostFinance, the agreement below:
I hereby acknowledge and agree that my data and the data of my shoppers will be stored by the software provider customweb GmbH, Winterthur in the data-cloud of Amazon Web Services EMEA SARL, Luxembourg (subsidiary of Amazon Web Service Inc., USA) on their servers in Ireland and checked by the firewall of Cloudflare Inc., USA. Abroad my data is no longer subject to the Swiss Data Protection Act and banking secrecy. I hereby undertake to inform my shoppers accordingly.
Checkout appears to be more than just a PSP. It resembles an ERP (Enterprise Resource Planning). At Checkout you can submit a customer's detailed purchase address, delivery address, each product's amount, name, quantity, sku, type, discounts, shipping and fees.
As your customer's data will be hosted outside Switzerland, which you may not prefer, three anonymous order options have been introduced by YourShop:

Purchase amount	YourShop sends Checkout only the purchase amount.
Name and Email	YourShop sends Checkout the customer's first name, last name, email address, and purchase amount.
Everything	YourShop sends Checkout everything.

1)	Fill the Checkout provided parameters User ID, Authentication Key, and Space ID into the YourShop BackOffice.
2)	Click all the logos for which you will take payment at Checkout. The YourShop FrontStore shows these logos.
3)	In the YourShop BackOffice, specify the currencies you handle at Checkout and specify the primary currency. YourShop takes the primary currency, if one of your shop currencies is not supported at Checkout.
4)	Click [Save] to accept payments via Checkout.
