ERI reader not being part of the onboard ERI equipment

NOTE 1 An external ERI reader is fitted neither within nor on the outside of the vehicle.

NOTE 2 A distinction is made between proximity, short-range (DSRC), and remote external readers. A proximity reader can be a PCD (proximity coupling device) as specified in ISO/IEC 14443. A short-range external ERI reader may be a part of roadside equipment, handheld equipment, or mobile equipment. A remote external ERI reader may be part of the back office equipment (BOE).
