Union Smart manufactures premium, custom-printed NFC Audio Story Cards for toy brands, educational publishers, and B2B enterprises worldwide. These innovative tap-to-play RFID cards provide a magical, screen-free listening experience for children. By embedding a high-performance NFC chip (such as NTAG213 or NTAG215) inside a child-safe, durable card, kids can instantly trigger audiobooks, lullabies, or educational content on compatible smart speakers. Benefit from our factory-direct wholesale pricing, OEM custom illustration printing, and bulk chip encoding with an MOQ starting at 1,000 pcs.

As parents increasingly seek alternatives to tablet and phone screens, screen-free kids audio players have exploded in popularity. Our programmable NFC story cards act as the physical keys to this digital audio content. When tapped against a designated NFC reader or smart speaker, the embedded chip instantly communicates via 13.56MHz frequency to play the linked audio file.


As a direct B2B factory, Union Smart provides complete manufacturing solutions for your brand:

Please note: Union Smart is an OEM card manufacturer. We supply the physical, encoded smart cards. We do not manufacture the audio player hardware or provide the content management software.
Most screen-free audio players and custom smart speakers utilize the NXP NTAG213 or NTAG215 chips. These operate at 13.56MHz and offer the perfect memory capacity to store the specific numeric ID or URL that tells the speaker which audio track to download and play.
By default, NTAG chips are rewritable. However, for commercial toy and publishing applications, we highly recommend that we permanently lock (read-only) the chips during our factory encoding process so that consumers cannot accidentally overwrite the story data.
Yes. We use high-quality, non-toxic PVC or eco-friendly biodegradable PLA. We apply a durable lamination that makes the cards water-resistant and drool-proof, and we finish them with rounded corners to ensure there are no sharp edges.
Absolutely. If you are launching a "10-card story series," we can split your MOQ across the 10 different artwork designs and encode the corresponding 10 different audio trigger links.
Yes. Our factory-direct B2B model is designed to scale with your success. While our standard MOQ is 1,000 pieces, our unit cost drops significantly for high-volume mass production runs.
