TripKey has identified the source of their on going TripKey problems as the endorsement in Rick Steves guidebook. 😁
As one of the many trying to use the process which I did learn about via RS info, I found the following email from TripKey ironic.
When success becomes a challenge....
The recommendation we received in Rick Steves's Europe, the top-selling guidebook about the Netherlands sold in North America, got us a sudden wave of customers. The demand for TripKey increased faster than we had expected. Some customers were unable to get a card. We sincerely apologise for the inconvenience.
Also, I had registered for TripKey before they stopped accepting registration and I was able to pick up the card in Amsterdam on May 1st. I haven't used it yet because when arriving at Schiphol and not knowing if I could actually get the card, I bought 3 day transit pass. I will use TripKey starting Friday.
