RFID vs Barcode

Advantages of the RFID system as opposed to a barcode

desplaza el contenido
BARCODE RFID
Reading method Visual reading. By radio frequency. No visibility required.
Simultaneous reading Individual reading. Simultaneous reading Up to 1000 labels at a time.
Reading speed Manual reading. One per second. Automatic reading. One thousand per second.
Durability Subject to surface damage that makes the label useless. Possibility of protection with plastic substrates.
Storage of data UPC. Identification of a generic item. EPC. Permits individual identification.
Flexibility of information Does not allow rewriting. Permits rewriting.
Falsifications Easily reproducible. No puede duplicarse con facilidad.

FALSIFICATIONS
Barcode RFID
Easily reproducible. It cannot be duplicated easily.
  • The barcode reading method is visual (requires laser vision), while the RFID does not require visibility.
  • An RFID system can read the inside of boxes without the need to open.
  • The barcode requires individual reads, while the RFID can perform simultaneous reads.
  • An RFID system can read up to 1000 tags at a time with the resulting saving of time.
  • Reading the barcode is slow and sometimes a rough surface or dirt on the label can make it even more difficult to read. Instead, RFID is a fast, automatic read.
  • The barcode label is superficial for its visual reading method, is difficult to protect, and can be damaged. In contrast, the RFID tag can be protected with plastic substrates or foam.
  • The typical barcodes only identify one product (such as EAN). The Electronic Product Code (EPC) is the information transmitted using RFID technology. It is a unique alphanumeric code identifying each item unambiguously from other items.
  • The information printed on a bar code is fixed and cannot be changed. However, the electronic information encoded on the RFID tag can be recoded and, therefore, can be rewritten as often as needed.
  • The barcode is a visual and easily reproducible technology while the RFID information is easier to hide and is encrypted.
