Wɔ 1999 mu no, ɔbenfo bi a ne ho akokwaw wɔ Massachusetts Institute of Technology de EPC Open Network ho adwene a wɔde adi dwuma kɛse wɔ International Barcode Organization (EAN.UCC), Procter & Gamble (P&G), Coca{2}}Cola, Wal-Mart, Fedex, Fedex, Nestle, British Telecom Sun, Philips, philocoms 83 Deigative 1 hyɛɛ aseɛ. Wɔ Ɔkɔtɔberɛ 2003 mu no, wɔde EPC Globle Global Organization no sii hɔ wɔ aman ahodoɔ so de hyɛɛ EPC ne Internet of Things a wɔde bedi dwuma no ho nkuran.

EPC mmara no yɛ awo ntoatoaso foforo a wɔde yɛ nneɛma a wɔde kyerɛw nsɛm a amanaman ntam barcode ahyehyɛde no de sii hɔ. Original product barcode no yɛ code a wɔde kyekyɛ nneɛma mu nkutoo. EPC ne sɛ wɔde wiase nyinaa code soronko bi bɛma ade biako biara. EPC code no fa 96-bit (binary) kwan so. coding nhyehyɛe.

RFID Electronic Label yɛ mfiridwuma a ɛho akokwaw, EPC Electronic Label yɛ wiase nyinaa biakoyɛ gyinapɛn, na ne bo yɛ mmerɛw yiye. Ɛlektrɔnik tag a wɔde RFID mfiridwuma di dwuma no yɛ ɛlɛtrɔnik chip a ɛyɛ ketewaa sen aburow a ɛyɛ 1/5 ne antenna a ɛyɛ mmerɛw. Ɛlektrɔnik tag no yɛ teateaa te sɛ krataa na wobetumi ayɛ no kɛse te sɛ postage stamp anaa ketewaa bi. Ɛdenam gyinapɛn ahorow a wɔaka abom, bo a ɛso tew kɛse, ne nsɛm a wɔde sesa wɔ Intanɛt so no su ahorow so no, EPC kɔmputa so nkyerɛwde ahorow no ama RFID kɔmputa so nkyerɛwde a wɔde di dwuma no akɔ soro. Wɔ afe 2006 mu no, wiase nyinaa kɔmputa so tag a wɔde di dwuma no duu ɔpepepem 60 kosi ɔpepepem 80 afe biara.

RFID radio frequency identification system no ka EPC electronic tags ne RFID akenkanfoɔ ho. EPC ɛlɛtrɔnik tags no yɛ nɔma soafoɔ. Ɛnam RFID akenkanfoɔ so no, wɔbɛtumi akenkan EPC ɛlɛtrɔnik tags no ho nsɛm, na wɔde nsɛm no akɔ Intanɛt so Middleware denam RFID akenkanfoɔ so.

EPC Information Network System no yɛ afã abiɛsa titiriw: EPC Information Service, EPC Middleware ne Discovery Service:

1. EPC Information Service (Software Support System of EPC System), a wɔde di dwuma de hu sɛnea EPC nsɛm a wɔn a wɔde di dwuma awiei no di nkitaho wɔ Intanɛt so nneɛma tebea mu no.

2. EPC Middleware yɛ nkitahodi a ɛda RFID akenkanfo ne nsɛm ho nhyehyɛe ntam.

3. Discovery dwumadie no nya EPC Data Access Channel ho nsɛm a egyina ɛlɛtrɔnik afiri mmara so. EPC nsɛm a wɔhwehwɛ no titiriw ne Object Name Resolution Service (ONS) ne nnwuma a ɛboa.

Ɛsɛ sɛ EPC Intanɛt so nneɛma ho nhyehyɛe yɛ EPC koodu, EPC tags ne RFID akenkanfo, mfinimfini nneɛma nhyehyɛe, nneɛma din ho nsusuwii (ONS) servers ne EPC nsɛm ho dwumadie titiriw na ama wiase nyinaa Intanɛt so Intanɛt abam.

EPC Mmara no wɔ tumi a ɛdɔɔso a wɔde kyerɛw nsɛm, efi nnipa dodow a wɔwɔ wiase nyinaa (bɛboro ɔpepepem 6) kosi aburow a ɛwɔ wiase nyinaa (a wobu akontaa sɛ ɛyɛ ɔpepem 100), na EPC mmara no wɔ baabi a ɛdɔɔso a wobetumi ahu nneɛma yi nyinaa. Sɛnea ɛbɛyɛ a EPC Mmara no bɛyɛ soronko no, EPC Global no nam aman ahorow a ɛwɔ wiase nyinaa mmara ahyehyɛde ahorow so kyekyɛ ɔman EPC Mmara no, na ɛde nhyehyɛe a ɛne no hyia a wɔde di dwuma no si hɔ.

EPC koodu no yɛ version nɔmba, product domain name management, product classification part ne serial number. Mprempren, coding ahorow a wɔde dii dwuma wɔ EPC nhyehyɛe no mu no titiriw ne 64-bit, 96-bit ne 256-bit.

EPC encoding no wɔ su ahorow a edidi so yi:

EPC coding gyinapɛn no ne EAN.UCC coding gyinapɛn a wɔde di dwuma mprempren no hyia. GTIN yɛ EPC coding nhyehyɛe no fã titiriw. Mprempren gtin, SSCC, GLN, ne nea ɛkeka ho a wɔde di dwuma kɛse no betumi adan EPC yiye.
