An ID card and/or cell phone holder provides position identification, 2-way communication, and panic control features for emergency communication. Contemplated holders include those configured as a wallet, arm band, belt clip, or money clip, and can additionally or alternatively be adapted for use with a key ring, lanyard, or other carrying adapter. Position identification circuitry, the communication circuitry, and the panic control interface can be physically distributed between or among at least first and second cards or other components.
