Value token with slug having rfid and electromagnetic detection features

摘要: Value tokens, e.g. gaming chips, are formed with a slug having an RFID microchip embedded or encapsulated inside and EM coil either wrapped around the periphery of slug. The is by injection molding two plastic halves spacing therebetween for accepting microchip. from weighted including fillers such as copper, brass and/or tungsten to add extra weight halves. placed on same radius antenna within chip at outside minimize interference between signals minimizing metal in field. For example, may be wound groove outer
