In the past few years, we've seen a lot of new payment technologies deployed in the US. Just to name a few, there's Square, Google Wallet, Square Wallet, Bitcoin, Coin, Wallaby, and ISIS (the last 3 only being launched this week). Some of these are pretty worthwhile. Some of these are pretty terrible. Here's a quick rundown of what each is.
I swapped out my T-Mobile SIM card yesterday for one of their new Advanced Security SIMs, and WiFi calling suddenly stopped working. I poked around the Internet and found a lot of posts about REG09 and REG99, but not much on REG90 except one misinformed post where someone said that they had to return their phone.
A Creole coonass just trying to get by. I live in San Francisco and work as a digital plumber for the joint that runs this thing. (Square/Weebly) Thoughts are mine, not my company's.
