How do I know if my A12 is wireless charging compatible 

[JAMES4578]

Pretty sure the A12 does not support Wireless charging ,  does support Fast Charging.   From Manual  :

Wired charging:
Connect the USB cable to the USB power adaptor and plug the cable into the device’s
multipurpose jack to charge the battery. After fully charging, disconnect the charger from the
device.

Quick Charging 
Launch the Settings app, tap Device care → Battery → Charging, and then activate the
feature you want.
• Fast charging: To use the fast charging feature, use a battery charger that supports
Adaptive fast charging.
• While charging, you cannot activate or deactivate this feature.
• You can charge the battery more quickly while the device or its screen is turned off.  

Wireless charging not mentioned in Manual and this Samsung response says not compatible with A series  https://www.samsung.com/us/support/Wireless Charging

You're right, @JAMES4578. I just double checked this and can confirm that the Galaxy A12 does not support wireless charging, but does support 15W Fast Charging with the official charger and cable.

I'M TYPING IN ALL CAPS BECAUSE I WANT EVERYONE THAT HAS A GALAXY A12, like me, TO SEE MY RESPONSE. YES!! THE A12 DOES SUPPORT WIRELESS CHARGING!! You must take your case off, & purchase a compatible CHARGER in order for it to work properly. Buy it from SAMSUNG!
