What is RFID? • Identification technology that uses RF • Tags come in all sizes and shapes • Two main types of tags • Active: own power source (60 -300 feet) ($10 -$80) • Passive: powered by reader (2 inches-30 feet) ($0. 20 -$3) • RFID tags are small radio transmitters and receivers • Mainly three frequency types • LF: 125 -134. 2 k. Hz • HF: 13. 56 MHz • UHF: 868 -928 MHz

RFID Tag Frequencies • Low Frequency • • good penetration of materials (including water) less susceptible to effect of metal • • supports anti-collision read tags lighter and cheaper than LF tags more memory capacity than LF tags maximum read range: 4 feet longer read range than HF maximum read range: 12 inches • High Frequency • Ultra-High Frequency • behave more like light waves than radio waves • perform poorly with water and metal • read range: 10+ feet

Factors Affecting Reader Choice • Read/Write range • Materials present in surroundings • Tag memory needed • Cost • Tag form (size, shape, etc. . ) • Host application and Communication Protocol • Power Consumption • Antenna size • Interference

Readers Used • Skyetek M 1 Reader (Storage Room) • Intensecomp Reader (Products Gate)

Tasks Completed • Achieved reader connectivity • Performed Single Read • Performed Anti-collision read • Found maximum tag read ranges • Testing in presence of water and metal • Ran sample codes • Skyetek M 1 reader: C, Java, C++, VB • Intensecomp reader: VB. NET, Java, VB, C

Skyetek M 1 Reader Tag Ranges • Maximum tag ranges 4 -5 cm 5 -7 cm 10 -12 cm

Skyetek M 1 Reader Tags • Larger the tag, greater the range • more signal reflection • More the tags, less the range • less power supplied per tag • Presence of water and metal • water and metals absorb HF waves • reduces range greatly

Skyetek M 1 Reader Problems • Hardware • Reader connectivity problem • power supply was not connected properly • No tags read problem • internal antenna was not connected • Read range problem • built own antenna • Software • Java programs not running • had to add Java comm. API classes

Skyetek M 1 Reader (Hardware) • Building the antenna Single Loop Antenna Copper Tape External Antenna

Skyetek M 1 Reader (Hardware) • Adjust C 3 and C 4 values to obtain maximum range

Skyetek M 1 Reader (Hardware) • Antenna built and test read was successful

Skyetek M 1 Reader (Hardware) • Reading range from antenna very poor • use copper tape for antenna material without antenna with antenna
