The new X1+ Card offers unique lounge benefits, solid travel insurance and a reasonable annual fee

On the heels of the public release of no-annual-fee X1 credit card last year, the fintech startup X1 has unveiled a new rewards credit card – the X1+ Card.

The X1+ will utilize the same rewards program and smart technology as the X1 Card. But the X1+ features enhanced travel insurance, lounge access when your flight is delayed and expanded redemption options to go along with a $75 annual fee.

This card has some interesting benefits and unique security features that aren't common with other credit cards. However, its rewards program is limited because you can only redeem points for maximum value at specific merchants. So you may find more value with a card with more flexible redemption options.

The new X1+ isn't publicly available, but there is a waitlist you can sign up for.

One standout feature of the X1+ Card standout is its disposable virtual card numbers. You can create one-time use virtual card numbers or card numbers that are auto-canceled after 24 hours, which is ideal for free trials because you won't accidentally be charged after the trial period ends. For additional security, you can opt for a card with no visible card number or security information on it.

An X1+ Card holder's credit limit is based heavily on current and future income. Because X1 places a lesser emphasis on credit score, you may be able to get approved with a lower credit score than you'd expect and possibly have access to a larger amount of credit.

The X1+ Card is a part of the same rewards program as the no-annual-fee X1 Card, with a few additional earning and redemption options. You can earn unlimited rewards on every single purchase at the following rates:

• 2X points per $1
• 3X points every time you spend $1,000 in a month
• 4X points at Expedia, Hotels.com and VRBO
• 4X, 5X and even 10X points per $1 for up to a month when you successfully refer someone to the card
• Up to 10X points when cardholders shop through the X1 app

You can earn bonus rewards when you refer someone and they get the card, but it's not a simple bonus. Instead, you'll earn at least 4X points on all purchases for up to 30 days per referral. The referral program is also a bit of a lottery — sometimes the referral will unlock 5X or even 10X points.

The points you earn with the X1 or X1+ Card are worth 0.7 cents each for cash back and one cent each as a statement credit for purchases with over 50 brands, including Airbnb, Apple, Best Buy, Amazon, Etsy and many more. X1+ cardholders have additional redemption options that include:

• Four Seasons Hotels and Resorts
• Intercontinental Hotels and Resorts
• Westin Hotels and Resorts
• Emirates
• Hawaiian Airlines
• JSX

For frequent travelers, the X1+ Card has built-in protections, such as primary rental car insurance, lost and delayed baggage coverage and trip cancellation protection. The card also has purchase protection, extended warranty coverage and cell phone insurance.

One of the most unique features of the X1+ Card is its lounge access benefits. Instead of getting a specific lounge membership with the card, the cardholder and up to four additional passengers will get complimentary lounge access if a flight is delayed by one hour or more.

CNBC Select was told the lounge access benefit applies to more than 1,000 locations worldwide, including most lounges available through the Priority Pass network, but won't apply to Priority Pass restaurant partners. If your flight isn't delayed, you'll have the option of purchasing lounge access.

The X1+ Card has a $75 annual fee.

The X1+ Card is an affordable option for anyone looking for a card with good insurance benefits and a solid earnings rate. It also has a number of unique benefits that could be useful depending on your spending and travel habits, like virtual card numbers and lounge access when your flight is delayed.

The main drawbacks of the card are the limits of its rewards program and the fact that it doesn't currently have a welcome bonus. You may find that a card or rewards program with flexible redemption options provides more value.

For example, the Chase Sapphire Preferred® Card allows you to transfer your points to 14 travel partners, redeem points for one cent each as cash back and pay for travel booked through Chase Travel℠ at a rate of 1.25 cents per point. It also has a welcome offer of 75,000 bonus points after spending $4,000 on purchases within the first three months of account opening and only a $95 annual fee.
