Many people ask if Tarot works if you're not there with the reader in person. The answer to that question is yes, it does still work. I've read over the phone and over chat, and as long as the person at the other end is focused on the reading, there haven't been any problems.
That being said, there are certain things I can't do if you're not with me in person. I can't light my citrus-sage candle, you won't see that I have a Guatemalan coin in my pocket (not that you'd see that anyway) and an amethyst crystal (wand) at my right hand. It's difficult for me to let you see enough cards of the deck in order for you to really choose which deck you want, and I certainly can't have you hover your hand over each to determine which one speaks to you. There are ways around that, especially with internet, but it's still not quite the same.
I can't ask you to shuffle the deck yourself. There isn't the intimacy of the two of us sitting at my kitchen table. I can't offer you something to drink or some nibbles.
But there are also things I can do with technology that would be difficult to do in person. I can take a picture of your spread for you to keep. I can give you a link to where you can purchase any particular deck I use, if you really like the deck. My explanations, especially via chat, can be kept and reviewed later for greater insight. A lot of people bring note pads to a reading, which I encourage, in case they want to write things down, but that can also be cumbersome when you're writing and also supposed to be touching the cards and being spiritually present.
Every way of reading Tarot has its advantages and drawbacks. I enjoy creating peaceful space for people to have a reading, so in-person readings are probably my favorite, but I also really like being able to give someone something to keep from their reading. A lot of readers will record sessions and give a web link to access it to the person they are reading for. I have not started that practice yet, but probably will in the future.
I hope that answers that question for you, and I look forward to reading for you, in any medium, in the future.
