Data Matrix

Data Matrix, nke akpọrọ Data code, bụ nke International Data Matrix (ID Matrix) chepụtara na 1989. Enwere ike kewaa data Matrix na ECC000-140 na ECC200, ECC200 na-ejikarị eme ihe. Data Matrix na-akwado mkpụrụedemede ASCII na mkpụrụedemede ASCII sara mbara. a na-ejikarị eme ihe maka njirimara ọnụọgụ nọmba ngwaahịa obere olu.

Grid Matrix

Grid Matrix, nke a na-akpọ koodu GM, bụ koodu 2d square. Ihe eserese koodu ahụ bụ modul macro square, na modul macro ọ bụla nwere nkeji 6 × 6 square.

Koodu 2d ekpokọtara / ahịrị

A na-akpọkwa koodu mmanya 2d stacking / ahịrị-yiri stacking 2d bar koodu ma ọ bụ oyiri-parallel 2d bar code. Ụkpụrụ nzuzo ya dabere na koodu mmanya 1d, nke etinyere n'ime ahịrị abụọ ma ọ bụ karịa ka ọ dị mkpa. Ọ na-eketa ụfọdụ njirimara nke koodu mmanya 1d na nhazi koodu, ụkpụrụ nkwenye na ọnọdụ ọgụgụ.
