    NFC Sentinel

    Posted by Luke Bellamy on 1st Apr 2021

    The sentinelX is great for me, as it fits in my phone case flip panel, so I do not even need to take the card out to re scan it every 4 hours. It would be nice if you could somehow extend the time to 8 hours for overnight, maybe by doing an in app task. Glad I got it on a free offer/

    SentinelX NFC

    Posted by Sander on 1st Apr 2021

    I am very pleased with my Sentinel NFC, the advantage over the old Sentinel BLE is that it is easy to carry in the case of my phone. In addition, it does not use a battery. In addition, the sharing option is a nice and desirable addition because it allows you to earn additional COIN.

    Great Tool

    Posted by Gianluca Sartoni on 31st Mar 2021

    I bought a sentinelX a few month ago, i use it every day when i walk but also at work in office. It’s a great boost for mining a lot of XYO token! It’s great

    It certainly helps earn COIN more easily

    Posted by Ron Brind on 31st Mar 2021

    This update really is worth having, it's easy to use, store and apply so what's stopping you getting yours? COIN is exchanged for XYO and the value is increasing big time! Thank you to all involved.

    Excellent addition

    Posted by Lennie Jarratt on 30th Mar 2021

    I bought my Sentinel NFC with coin. It took me 8 months to earn those Coin. Since buying it I have earned the it all back plus more in just over 2 months. It’s great. I should have bought it much sooner. It is worth it.

    Improved Earnings

    Posted by Ali on 30th Mar 2021

    The sentinel is nice. I like the improved earnings and that I can let others scan it and I get a little kickback. I keep mine on me in my wallet.

    Different than the Bluetooth Sentinel

    Posted by Jaime Gatwick on 19th Jan 2021

    I really like the fact that this doesn't require any battery. Don't get me wrong, the bluetooth one is good, but the fact that this doesn't require any battery is super cool imo.

    Longer Scans Please

    Posted by Ryan L. on 19th Jan 2021

    I just got the SentinelX, and it's really great for boosts BUT I want longer scans!!! Four hours is not enough for me, I have to put my phone away for work so I forget to scan it again sometimes. I had the Bluetooth one and it was pretty good but I really liked the no battery with this one. thinking I may get the subscription because I want to get 24 hour scans
