Abstract: Embodiment methods, devices, non-transitory processor-readable storage media, and systems for conducting transactions based on proximity without sending secure information via short-range wireless signaling, comprising broadcasting, by a point-of-sale device, a short-range wireless message requesting a peripheral response, broadcasting, by a client device, a short-range wireless message indicating that the client device is available as a peripheral, receiving, at the point-of-sale device via an established short-range wireless connection, identifying data of the client device, transmitting, by the point-of-sale device to a server, a message including the received identifying data of the client device, transmitting, by the server to the point-of-sale device, an encrypted nonce, transmitting, by the point-of-sale device to the client device via the established connection, the encrypted nonce, decrypting, by the client device, the encrypted nonce, determining whether the decrypted nonce matches the unencrypted n
