Vocalid® technology Technical Characteristics

Vocalid® smart card Thickness: 0.80 mm Length: 85.5 mm Width: 54 mm Magnetic stripe 7816 Synchronous protocol Chip: special circuit developed by Elva and manufactured by ATMEL

External Acoustic Module (EAM):

Thickness: 14 mm Length: 60 mm Width: 40 mm Weight : 30 g

The External Acoustic Module embeds a switch, a battery and a piezoelectric transducer
The switch: Simply push it to trigger the emission of an authentication sound sequence.
The battery: CR2016 type providing the power required by the system. The battery lasts for 10000 uses, or 2 to 3 years depending on the associated application.
Piezoelectric transducer: thin ceramic membrane supplied by Murata. Driven by the chip, it emits the authentication sound sequence.

The acoustic interface:
The identification data calculated in the chip are transmitted to the external acoustic module. the card is activated when the EAM switch is pushed. The process is designed for use over a computer microphone or telephone handset.
The authentication sequence is transmitted as a loop in FSK format (old modem standard).
In the field of acoustic authentication, the Vocalid^® solution offers the best performance (100% recognition within two seconds, under standard communication conditions and card usage).

The other interfaces: compliance with existing standards

• ISO contacts
  Vocalid^® works in a traditional chip reader: an ISO reader can read and process the data contained in the chip.
• Magnetic stripe
  Vocalid^® can be used in traditional payment methods because of its magnetic stripe. This transaction method is the one most widely used.
• Other types of reader
  The standard processes for printing and embossing cards can provide visual personalization

for the issuer and the user of the card. It is possible to use Vocalid^® in credit card imprinters, for example.
