It's time to use EventFlows to make the check-in process easy!​ EventFlows is an app to help event holders by providing fast and easy ways for participants to hold an event check-in. Three ways to check in your participants: 1. Bar-code Check-in You can print bar-codes on participants' tickets, record these codes in this app, and then scan the code on the tickets when checking participants in. 2. NFC Check-in If your device supports the NFC feature (please refer to the Apple Website for your device capabilities,) you can embed NFC chips (those compatible with CoreNFC framework) in participants' tickets, and use the supported devices and this app to check your participants in with NFC! Make sure to select the NFC method and enter the NFC chip ID ahead of time if you want to try out this feature. 3. App Check-in You will enter a list of the participants' email addresses. Participants will download this app and register for the app. At the time of the event, you will display a QR code to let participants scan the code on their phone to check-in. If the participants don't have the device or the app at the time of check-in, they can manually verify and enter their information on your screen.

Grade.IQ uses advanced AI to analyse your Pokémon cards and estimate professional grades before you submit — saving you time and money. PHOTO-BASED GRADING Simply photograph your card and our AI analyses centring, corners, edges, and surface condition to give you an estimated grade in seconds. MULTIPLE GRADING STANDARDS Get estimated grades for PSA, Beckett (BGS), ACE Grading, CGC, and TAG — built around each company's published standards, all in one scan. CLAHE ENHANCEMENT FILTERS Grade.IQ doesn't just look at your photo. It applies professional CLAHE imaging filters (adaptive histogram equalisation) to reveal micro-scratches, edge whitening, and surface texture invisible to the naked eye — for a sharper, more accurate grade. REAL MARKET VALUES See actual eBay sold prices for graded copies of your card, so you know exactly what it's worth at every grade level — and which company gives you the best return. TCG ADVISOR Chat with your own AI card expert for instant answers on values, grades, deals, and whether a card is worth submitting. DEEP GRADE MODE Capture up to 16 photos including close-ups of all 4 corners for the most accurate AI assessment possible. BULK GRADING Grade up to 20 cards at once — perfect for sorting through a collection quickly. CROSSOVER GRADING Already own a graded slab? Estimate how it could score with a different grading company before you cross it over. JAPANESE CARD SUPPORT Full support for Japanese sets with Cardmarket EU pricing. Whether you're a collector, trader, or serious grader, Grade.IQ gives you the edge before your cards go in the post. BUILT BY THE COMMUNITY, FOR THE COMMUNITY I'm a solo developer and a collector just like you — and this is the very first app I've ever built. I made Grade.IQ for our community because it's something I wanted myself. As a one-person team you may run into the odd bug, but I'm fully committed to fixing them quickly and making the app better with every update. Your feedback means everything — thank you for giving Grade.IQ a try.
