Kim Gilmore asked 3 years ago I'm working on a project that requires a sound-alert feature when pinged by an RFID signal. It needs to be durable, weather-resistant and no larger than a poker chip, and if power is required, it would need to use a watch battery or the equivalent. Do you have any suggestions?

Kim,
I am unaware of such a device, but if any of our readers know of something that would fit the bill, they are invited to please let me know. I will then pass that information on to you.
