Medeiros 2 D Barcodes (cont.) n Data Matrix Data Matrix – matrix, up to 500 characters, error correction – scaleable down to.001 in square – marking small items – IC’s, single dose meds n Maxicode Maxicode – matrix, 93 characters, error correction – 1 inch square, locating bullseye – package sortation and tracking

12. The Marcus Department of Industrial and Manufacturing Engineering at Penn State Facility Layout and Material HandlingD. J. Medeiros Bar Code Readers n handheld or fixed mount n contact wands (pens) – slow, inexpensive n laser scanners – longer distance scanning – fixed or handheld – can read stacked bar codes n image scanners – fixed or handheld – can read stacked bar or matrix codes

13. The Marcus Department of Industrial and Manufacturing Engineering at Penn State Facility Layout and Material HandlingD. J. Medeiros Cards n magnetic stripe – low cost – low storage capacity – contact reader – can be rewritten – easily damaged (less easily for high coercivity stripes) n example: credit cards, bank cards

14. The Marcus Department of Industrial and Manufacturing Engineering at Penn State Facility Layout and Material HandlingD. J. Medeiros Cards (cont.) n “smart cards” – imbedded microchip n memory only – stored value cards n microprocessor – high storage capacity – can be rewritten – can execute programs n example: some credit cards

15. The Marcus Department of Industrial and Manufacturing Engineering at Penn State Facility Layout and Material HandlingD. J. Medeiros Radio Frequency Tags n transponder (tag) is programmed with information n reader has an antenna which sends radio signals to activate tag, read or write it n types of tags – active (has battery) n read and write – passive (activated by reader) – often read-only n noncontact, non line-of-sight

16. The Marcus Department of Industrial and Manufacturing Engineering at Penn State Facility Layout and Material HandlingD. J. Medeiros RFID Applications n railroad cars, commercial trucks n automobiles on assembly lines n parts carriers in hazardous environments n toll collection on highways n theft prevention in retail

17. The Marcus Department of Industrial and Manufacturing Engineering at Penn State Facility Layout and Material HandlingD. J. Medeiros Why RFID? n tags can be used in harsh conditions – usually housed in protective packaging n tags can be read over distances greater than 90 feet n tags can be read through snow, grime, cutting fluid, paint, etc. n tags can be read at high speed n more costly than bar code n lack of standardization between manufacturers

18. The Marcus Department of Industrial and Manufacturing Engineering at Penn State Facility Layout and Material HandlingD. J. Medeiros Contact Memory n a memory chip in a stainless steel case that resembles a button battery n read by touching the case with a probe n read only or read-write n license plate or portable database n additional capabilities can be built in – real-time clock – temperature sensor – cryptography

19. The Marcus Department of Industrial and Manufacturing Engineering at Penn State Facility Layout and Material HandlingD. J. Medeiros Use of Contact Memory n asset tracking n access control n digital cash n maintenance records n store manufacturing history for products
