The National Radio Systems Committee has introduced a unique Radio Data System Program Identification code for US FM translators. One type of metadata transmitted by RDS subcarrier is the PI code, which is used by the receiver to uniquely identify the audio program being broadcast by the FM station.
When triggered by an electromagnetic interrogation pulse from a nearby RFID reader device, the tag transmits digital data, usually an identifying inventory number, back to the reader. This number can be used to track inventory goods. [1] Passive tags are powered by energy from the RFID reader's interrogating radio waves. Active tags are powered ...
The PI code allows the radio to identify the station across different broadcast relay stations. This in turn allows listeners to stay tuned to a network whilst travelling across the service area of multiple transmitters. The PI code is a 4-digit hexadecimal number. For example BBC Radio 1 has PI code C201. (The number itself is usually not ...

A label or tag containing the encoded data is attached to the item that is to be identified. Machine reader or scanner.
The QSA code and QRK code are interrelated and complementary signal reporting codes for use in wireless telegraphy . They replaced the earlier QSJ code. They replaced the earlier QSJ code. Currently, the QSA and QRK codes are officially defined in the ITU Radio Regulations 1990, Appendix 13: Miscellaneous Abbreviations and Signals to Be Used in ...
The only abbreviation recommended to indicate a Maidenhead reference in Morse code and radio teleprinter transmission was LOC, as in LOC KN28LH. [1] John Morris G4ANB originally devised the system and it was adopted at a meeting of the IARU VHF Working Group in Maidenhead, England in 1980. [2]
A Radio code is any code that is commonly used over a telecommunication system such as Morse code, brevity codes and procedure words. Brevity code
ISO/IEC 15693, is an ISO/IEC standard for vicinity cards, i.e. cards which can be read from a greater distance as compared with proximity cards.Such cards can normally be read out by a reader without being powered themselves, as the reader will supply the necessary power to the card over the air (wireless).
