There’s a very interesting section at the in the Apple Platform Security May 2022 document in the section covering transit and eMoney cards.
Adding transit and eMoney cards to a family member’s Apple Watch
Apple Platform Security May 2022 (p. 152)
In iOS 15 and watchOS 8, the organizer of an iCloud family can add transit and eMoney cards to their family members’ Apple Watch devices through their iPhone’s Watch app. When provisioning one of these cards to a family member’s Apple Watch, the watch is required to be nearby and connected to the organizer’s iPhone using Wi-Fi or Bluetooth. Family members are required to have two-factor authentication enabled for their Apple ID for this to occur. Family members can send a request to add money to a transit or eMoney card from their Apple Watch using iMessage. The content of the message is protected by end-to-end encryption, as described in iMessage security overview. Adding money to a card on a family member’s Apple Watch can be done remotely using a Wi-Fi or cellular connection. Proximity isn’t required.
Adding money, remote recharge, is a very handy function for stored value cards in a family setting, especially now that Apple Pay Suica • PASMO will support high school and junior high school school commuter passes from March 18.
Commuter passes (commute plans) are purchased in Suica or PASMO app and new versions are coming that support student ID certification. The student takes a picture of their school ID card in the app and uploads it along with a requested commute route. They can use student commuter passes on iPhone or Apple Watch, which is the only wearable option for Mobile Suica • PASMO. All other wearables, including Pixel Watch Suica, do not support commute plans, only regular Suica.
After the student ID is certified they complete the commute plan purchase. Here is where it gets interesting. If the student does not have a credit card, they can purchase it via the new ‘one time purchase’ option with a parent’s card. Most Tokyo high schoolers already seems to have a Mobile Suica or PASMO, but now that they don’t need the plastic card for going to school, they can buy a commute plan and toss the plastic. That means the Tokyo area HS set will finally be 100% mobile for payments and transit.
But what about the JHS set, especially the younger ones who might not have payments cards? This is where Apple Watch Family Sharing Suica via iMessage comes in handy:
“Hey ma, I need recharge!”
“I just gave you ¥5,000.”
“But that was Tuesday and I have to eat before going to the Juku, can’t study when I’m hungry”
Bing! The possibilities are endless.
