This may be a US and non-US market thing. Here is a related article. It looks like this applies only to the IONITY charging network in Europe:

More than 5,000 new fast charging points by 2025: Massive expansion by IONITY strengthens Audi’s charging offering

A well-developed charging infrastructure forms the very backbone of electrified mobility. That is why IONITY is investing around 700 million euros to install more than 5,000 additional fast-charging points by 2025. As such, the joint venture – in which Volkswagen, with its Porsche and Audi...

Thanks, certainly seems so. Much appreciated.

"Plug & Charge: Audi makes charging possible without an RFID card or app
Starting in December 2021, Audi will be offering a particularly premium form of charging exclusively on the IONITY network known as “Plug & Charge” (PnC). This refers to the ability to easily and securely charge an EV without an RFID (radio frequency identification) card or even an app. The authentication process takes place automatically at compatible charging stations via encrypted communication as soon as the charging cable is connected to the vehicle. Then the charging process also starts. And finally, billing is handled automatically on the basis of a contract on file. To use this system, drivers must have a PnC-capable Audi e-tron model (a new model with production date after calendar week 48/2021) and an active e-tron Charging Service contract. Users only need to activate the PnC feature in the myAudi app and in the MMI of their Audi e-tron."

Brand new car and eCS subscription required. Shame. With the app update I thought this was an "OTA" update for existing models.

 

After a free introductory year, the e-tron charging service becomes something like £18 per month. While it does give good reductions in the per kWh rate on Ionity chargers, we weren't using them anywhere near enough to make it worthwhile. That said, on the few times we travelled distances in that year, the e-tron charging card (RFID) was excellent.
