Barclaycard is teaming up with Uber to issue a credit card called the Uber Visa Card. While technically co-branded with the ride share company, there are almost no Uber related benefits, which is kind of confusing. Nevertheless this card, which will earn rewards in the form of cash back, has impressive cash back rates that (in most ways) beat other cash back cards.

You can't apply for the Uber Visa quite yet.

Get a $10 discount the next time you use Uber and pay via the Android Pay application. The promotion is applicable for only one trip within the United States, and you have until 7 PM ET on May 31, 2016 to use it.
How to Get the $10 Discount
Download Android Pay in the Play Store. Sorry iPhone users, I don't think you are eligible for this $10.

Facebook Messenger now allows you to book an Uber ride directly from a conversation.

To celebrate, you can get your first Uber ride booked through messenger for free, up to a $20 ride.
For a limited time, you’ll get a free ride the first time you use this feature (up to $20 value) with Uber. All you have to do to claim your free ride is link your existing Uber account or set up a new account within Messenger and request a ride.

What do 110 strangers think of me? Now I know, since I checked my Uber Rider rating in the app. Here's how:

1. Select the silhouette in a circle in the top left of the Uber home screen to bring up the menu.

2. Select "HELP."

3. Select "Account."

Select "I'd like to know my rating."

5. Select "Submit."

Your rating will appear. Mine is 4.8 stars out of 5.

I'm happy with 4.8. The rating is displayed when drivers are deciding whether to accept a ride, but I imagine most won't reject you unless your rating is terrible.

The Citi ThankYou® Premier Card changed its 3x categories to gas and travel on April 19. I covered just how broad those categories are in this post at the time.

Gas and travel purchases that earn 3 ThankYou Points per dollar include:

airlines
hotels
car rental agencies
travel agencies
gas stations
commuter transportation
taxi/limousines
passenger railways
cruise lines
bridge and road tolls
parking lots/garages
campgrounds and trailer parks
time shares
bus lines
motor home/RV Rental and boat rentals

At the time of the change, I hoped that Uber fell into the taxi/limousines category.

Uber is now offering one free ride up to a massive $30 to new users who sign up through a referral link. This limited time bump in the sign up bonus will only last for two weeks.

Uber is the world’s best taxi service because it has clean, courteous drivers and the easiest ride-ordering app imaginable. Tap, tap, tap, and a car whose progress you can track towards you is on its way.

New Uber users can get $30 for a free ride when they sign up through my referral link.

(I get $30 for a free ride too.
