AsReader RFID readers smaller than a credit card

The ASR-P35U: UHF band Desktop” RFID reader will replace the former ASR-P30U Desktop” reader and is significantly smaller at roughly the footprint of a credit card.  Because it is powered via USB-C, it is battery-less as its use is generally static on a desktop or mounted to a wall with included mounts.  It can be used with Windows and Android out of the box.  Use with iOS devices is possible with a power adapter, like those available for high-end cameras.

ASR-P37U: Same as the P35U, but half-sized, with an external antenna port, instead of a built-in one. Small enough to use attached to a drone, there is a wide variety of antennas with this small device for many different use cases. It is currently in use as a scanner for self-check-out terminals in retail and grocery stores in Japan.
