RFID Frequency Translator

An RFID-based system and method is disclosed which translates discrepant frequencies and protocols, for seamless communication across disparate devices. Any legal frequency is accepted, information transmitted in that frequency is translated then saved in allocated memory accessible to the other side, which receives and processes the information with an appropriate reader-equipped device such as cellphone, handheld device, or computer. HF for Near-Field Communication may be used as one frequency protocol, but is not limiting. A unique aspect is ability to power the translator at short range using the reader's field, eliminating a battery. A plurality of microcontrollers/memory modules is used. Microcontrollers receive information from one frequency interface by reading shared memory, then communicate to the other frequency interface by writing to its shared memory and signaling the presence of data. Microcontrollers monitor new data, await a response from the signaled interface, facilitating communication between two sides not otherwise in communication.
