I ordered the Greenlight cards for our children. Only one is a minor (and she uses a regular debit card) but two are special needs adults who are more vulnerable to financial scams or misjudgments. I also got one for a sibling with some similar issues though that is certainly not the Greenlight market.
So far it’s been a mixed experience. The Greenlight site has suprisingly poor documentation — basically some simplistic FAQs. They don’t document where the cards don’t work but from customer support I got:
Since our cards are meant for children, there are certain places that our cards will not work. Liquor stores, gambling websites or establishments, money orders, MoneySend and wire transfers are some examples of things that our cards will not work for. Since we are a prepaid debit card, we have also had families experience some trouble when attempting to use our cards to pay bills. We recommend not transferring funds to the Greenlight card that need to be used for utilities or other bills.
That seems reasonably, but it’s not the complete list. They don’t work for Patreon for example — my son wanted to donate there. Greenlight won’t provide a full list.
There’s also a problem with Greenlight.app behavior on one child’s phone. Again, this is undocumented, but I think there are two paths it should follow on launch. One path should enable access to card balance, the other is for requesting a card. On his phone it goes down the wrong path. Hard to sort out since, again, there’s no documentation.
The vibe I get from Greenlight is that is a venture funded effort that didn’t scale quickly enough …
