“Really easy to use”
I've sold so many photocards here that wouldn't sell in fan groups, so I'm happy to leave five stars! The interface is really simple and convenient, and the app keeps getting improved, so you can tell the team cares. Highly recommend, and my favorite feature is the Catalog!

“So convenient”
I thought it was a scam at first, but then I actually sold a card and got paid, and that's when I believed it. It really is convenient, and it's not as much hassle as setting up a shop on MyShip.

“Sellers ship really fast”
I've only bought photocards from two different sellers so far, but both shipped really fast and even surprised me with free homemade stickers as a little gift 🎁 They didn't charge any extra handling fees either. Such kind sellers!

Review from Google Play
Highly recommend. I used to buy photocards on Shopee, where prices were high and I couldn't tell if they were real or fake. Lately I've been buying here and found lots of cards I love. The audience is more focused, so cards sell more smoothly.

“Convenient”
The photocard categories are great. You can clearly label what you're selling or which card you want, and both sides are verified, so it feels safer.

Review from Google Play
I've been using it for a while. The team is very active in improving the app and the features keep getting more complete. Some cards that wouldn't sell in fan groups or on Shopee actually sold here, and I've also bought cards at great prices. Awesome, and I hope more users join!

PAYMENTS
Flexible payments, secure every way

Credit card
Taiwan users can pay by card directly, and credit card purchases are now open to Hong Kong and Macau users too.
Bank transfer
Each order gets its own virtual account number, so sellers never have to share a personal bank account, greatly reducing the risk of banks flagging third-party payments.
For digital goods like concert tickets and application codes, virtual delivery and the platform payout system protect in-person and overseas trades too.
